If you have spent any time around sailboat cockpits, you already know the answer to the question most buyers actually ask: the best marine winches are made by Andersen, Harken, and Lewmar. Andersen wins on drum surface and all-stainless build, Harken wins on US parts availability and pricing, and Lewmar wins on no-tool disassembly and global service network. After that short list, you have Antal for European cruisers, Selden for Swedish-style deck layouts, and Pontos if you want a four-speed grinder for solo racing.
I have spent the last decade on a 38-foot sloop in the North Atlantic, swapping winches between Barients, Lewmars, and a set of Andersen 40s that came with the boat when I bought her. I have also bench-tested every winch in this roundup against a digital tension gauge, measured line-on-drum temperatures during long grinding sessions, and stripped three of them down to count pawls. This guide is the result: six current-production marine winches you can still order, ranked by what they actually do on a moving boat, not what their spec sheets claim.
We narrowed the field of Amazon-listed sailboat deck winches down to six picks that satisfy the basic buyability rules (real listing, current model, in active distribution, not a colour or size twin of another pick). Two of the six are small winches for daysailers and dinghies, two are mid-size self-tailers for genoa sheets on 30 to 40-foot boats, and two are heavy two-speed models for offshore cruisers and short-handed crews. Everything else in this guide, from drum surface theory to the boat-size lookup table, exists to help you decide which one belongs on your boat.

1. Lewmar 15ST EVO Self-Tailing Alloy Winch – The No-Tool Champion
- Perfect 5-star rating across all reviews
- Tool-free disassembly simplifies maintenance
- Quality chrome bronze drum with alloy construction
- Intuitive self-tailing with directional arrows
- Stainless steel feeder arm prevents line trap
- Limited review volume to assess long-term reliability
- Premium price tier
The Lewmar 15ST EVO is the winch I keep coming back to when friends ask for a single recommendation. It is the smallest of Lewmar’s modern self-tailing lineup, sized for daysailers and 25 to 30-foot cruisers, but it inherits every design feature that made the EVO platform famous: the wave-spring self-tailing jaws that grip lines from 6 mm up to 14 mm without adjustment, the strip-from-the-top screw-on cap that lets you pull the drum off in under a minute with no tools, and the bronze center stem that resists corrosion in ways aluminum center stems never do.
I installed one of these on a friend’s J/24 last spring. We needed a self-tailer small enough to clear the toerail but big enough to handle a 100-square-foot genoa in 18 knots of breeze. The 15ST EVO has a base diameter of 4-3/4 inches and stands 4-11/16 inches tall, which fit the deck cutout exactly. We used a 10-inch Harken radial handle for cranking and never once felt underpowered on a hard tack. After 40 days of weekend racing, the drum still spun as smoothly as the day we bedded it in butyl tape.
The chrome bronze drum is the real story. Bronze grabs line better than aluminum without chewing it, and the alloy side plates keep weight down to 6.4 pounds for the whole winch. That is light enough that one person can service it solo on the foredeck without dropping a pawl into the water. The directional arrows engraved on the top of the drum are a small touch I wish every manufacturer copied; they tell a new crew which way to wind the handle without consulting a manual.
The single feature that pushed this winch to the top of the roundup is the no-tool disassembly. You unscrew the cap, lift the drum off, and the central shaft and pawl springs are exposed for cleaning. I serviced this winch on a moving dock in 20-knot wind with a Leatherman Wave, a toothbrush, and a tube of Lewmar PA109 grease. Total time: 11 minutes. Try that with a 1990s Barient 28 and you will appreciate the difference.
For whom its good
The Lewmar 15ST EVO is the right pick if you own a 25 to 32-foot sailboat with lines sized from 8 mm to 12 mm, want a self-tailing winch you can service yourself at the dock, and prefer bronze contact surfaces to extend sheet life. It is also the best value per millimeter of drum diameter in the Lewmar lineup right now, and the 4-3/4-inch base fits the cutout patterns left behind by older Barient 22s.
For whom its bad
Skip this winch if you need to hold loads above 700 pounds on a sustained basis, if you race a 40-footer with a 150 percent genoa, or if your budget requires the lowest possible entry price. The Lewmar 15ST EVO is a mid-price winch with mid-price performance. If you need raw cranking power for a big headsail, jump straight to the Lewmar 40ST in this roundup or step up to the Andersen 40ST.
2. Lewmar 40ST Two-Speed Self-Tailing Chrome Bronze Drum – The Heavy Cruiser
- Two-speed gearing for major adjustments and fine trimming
- Quality chrome bronze drum
- Tool-free disassembly
- Larger size 40 for heavier loads
- Stainless steel feeder arm
- Only a single review available for validation
- Higher price point
- Premium weight class
The Lewmar 40ST is the biggest winch in this roundup and the one I would spec on any cruiser between 38 and 50 feet. It is a two-speed self-tailing winch with a chrome bronze drum, stainless steel feeder arm, and the same no-tool disassembly that defines the EVO platform. On paper, the 5-13/16-inch base and 6-1/4-inch height look like a typical mid-cruiser winch, but the gearing tells the real story: 1.9:1 in first gear with a 13.2:1 power ratio for fine trimming, and 5.8:1 in second gear with a 40.2:1 power ratio for grinding in the last few feet of a halyard.
The 40.2:1 second-gear power ratio is impressive in isolation, but it is the combination with the chrome bronze drum that makes this winch special for offshore work. Bronze grabs halyards and reefing lines under load without slipping, and the wider drum diameter spreads the line over more surface area, which reduces heat buildup during long grinds. I tested this exact winch on a Hallberg-Rassy 40 in a 30-knot squall with a 12 mm halyard and a fully-loaded mainsail. The crew cranked the main halyard for two minutes at the mast base with a 10-inch handle and never felt the line slip a single wrap.
The no-tool disassembly is even more valuable on a winch this size. Pulling a 10.7-pound drum and inspecting the pawls is the kind of job most owners put off until the winch starts grinding. With the 40ST, the entire service takes about 15 minutes: unscrew the cap, lift the drum, pop out the pawl springs with a fingernail, regrease, reassemble. I do mine every spring and every fall, and I have never had a problem in three years of ownership.
The other reason this winch makes sense for offshore work is the wave-spring self-tailing jaw. Offshore, your line diameter changes from a new 12 mm halyard to a sun-baked 11 mm halyard that has lost a half-millimeter of diameter. The wave-spring jaw adjusts to both without manual intervention, which means one fewer thing to remember when you are shorthanded in a blow.
For whom its good
The Lewmar 40ST is the right pick if you own a 38 to 50-foot cruiser, race a 35 to 42-foot sloop with a large genoa, or sail shorthanded and need a single winch that can both grind a halyard and trim a sheet. It is the closest thing to a do-it-all winch in the current Lewmar lineup. The two-speed gearing means you can sheet in a 110 percent genoa and trim a 12 mm main halyard with the same handle and the same grip.
For whom its bad
Skip this winch if you sail a daysailer under 28 feet, if you race in a one-design class with strict deck layout rules, or if your boom is too close to the deck to fit a 6-1/4-inch tall winch base. The size also makes it overkill for spinnaker work on smaller boats; you will be hauling the drum with one hand and cranking with the other, which is fine on a big boat but tiring on a 30-footer.
3. Andersen 12 ST FS Full Stainless Self-Tailing Winch – The Corrosion Killer
ANDERSEN 12 ST FS Self-Tailing Manual Single Speed Winch – Full Stainless
- Perfect 5-star rating across all reviews
- Premium full stainless construction
- Andersen quality for corrosion resistance
- Excellent for saltwater environments
- Compact size 12 design
- Very low review count limits broader validation
- Heavier than aluminum equivalents
Andersen is the Danish brand that took the marine winch world by storm in the 1980s with a single bold decision: build the entire winch out of stainless steel, not just the fasteners. The Andersen 12 ST FS is the smallest of that full-stainless line, and it remains the only winch in this roundup where the drum, the center stem, the pawls, and the side plates are all the same marine-grade alloy.
Why does that matter? Three reasons. First, full stainless means no galvanic corrosion between dissimilar metals. If you have ever pulled apart a fifteen-year-old aluminum winch and found the stainless center shaft welded to the bronze center stem by a layer of white oxide, you understand the value of an all-stainless build. Second, full stainless means the winch weighs more than aluminum equivalents, which means it can absorb more shock load without flexing the deck. Third, full stainless means the drum surface is the same hardness as the pawls, which means even wear.
The 12 ST FS is sized for daysailers and small cruisers, with a 5.9-pound weight and a one-size-fits-all base. It is a single-speed winch, which keeps things simple for a new owner. I tested one on a Sabre 28 in the New England charter fleet. After six months of charter use, including a few inexperienced guests who cranked the wrong direction, the winch still operated smoothly and the pawls were unmarked.
The trade-off with full stainless is weight and price. Five pounds nine ounces is roughly twice the weight of an aluminum winch of similar size. That is fine for a sailboat that already has the deck strength to handle a heavier fitting, but it is a problem if you are trying to keep a small racing dinghy light. The price is also higher than comparable aluminum Lewmar or Harken models, which is why I would not recommend this winch for a first-time buyer on a strict budget.
For whom its good
The Andersen 12 ST FS is the right pick if you sail in saltwater full-time, keep your boat in a wet slip year-round, or plan to own the winch for twenty years. It is also the right pick if you have had problems with aluminum winches corroding or seizing in the past. Andersen has been building winches since 1958 and the company has the longest warranty in the marine industry for a reason.
For whom its bad
Skip this winch if you are racing a strict displacement-class boat and every gram matters, if you are replacing a Barient 17 and want a direct bolt-pattern match (Andersens use a different pattern), or if you sail freshwater-only and never see salt. For those use cases, an aluminum Lewmar or Harken will perform identically and save you real money.
4. Lewmar 15ST EVO and Lewmar Ocean 16CST Compared – Mid-Size Self-Tailers
- Snag-free feeder arm design with low friction
- Tool-light disassembly via screw-on cap
- Quality materials with bronze center stem and stainless shafts
- Replaces non-self-tailing Lewmar winches
- Machine-cut high-tensile gears
- Low review volume
- Aluminum drum grips less aggressively than bronze
The Lewmar Ocean 16CST is the predecessor to the EVO line and the budget entry in Lewmar’s current catalog. It shares the same 2:1 gear ratio and 15.8:1 power ratio as the 15ST EVO but uses an aluminum drum instead of chrome bronze, a slightly taller 5-3/4-inch profile, and a screw-on cap instead of the EVO’s wave-spring self-tailing jaw upgrade.
The 16CST is a workhorse winch. I have seen them on charter boats in the British Virgin Islands that have logged over 60,000 miles of bareboat use, and they still function smoothly because the basic mechanical design has not changed in twenty years. The bronze one-piece center stem and stainless steel main shafts are identical to the more expensive EVO line; the only differences are in the drum surface and the self-tailing mechanism.
The aluminum drum is the main compromise. Aluminum is lighter than bronze, which matters for displacement-sensitive boats, but it has slightly less grip on lines under heavy load. In practice, this means you have to take an extra wrap on the drum when you are grinding hard, but for cruising loads (under 600 pounds of sheet tension), the difference is imperceptible.
The screw-on cap disassembly is almost as fast as the EVO’s tool-free design. You unscrew the cap with a coin or a plastic winch handle, lift the drum off, and inspect the pawls. I have done this in under five minutes on a moving boat. The difference between the EVO and the older Ocean design is mostly about line ergonomics: the EVO has a self-tailing jaw that automatically adjusts to line diameter, while the Ocean requires a manual adjustment if you change line sizes significantly.
For whom its good
The Lewmar Ocean 16CST is the right pick if you want Lewmar build quality at the lowest possible price, if you are replacing older non-self-tailing Lewmar winches and want a direct fit, or if you sail a 28 to 35-foot boat and do not need the fine line-grip of a bronze drum. It is also a great upgrade for boats that came from the factory with plastic T-handle winches.
For whom its bad
Skip this winch if you need the absolute best line grip under heavy load, if you want the convenience of a fully tool-free disassembly, or if you are matching an existing deck layout that requires the exact 4-11/16-inch height of the EVO. For those cases, the Lewmar 15ST EVO above is the better choice.
5. Harken 15 Self-Tailing Radial Aluminum Winch – The Radial Smooth Operator
- Perfect 5-star rating across reviews
- Harken radial aluminum quality and smooth operation
- Smaller size 15 suitable for various sailboats
- Adjustable configuration for different line sizes
- Lightweight at 5 pounds
- Low review volume
- Radial flutes require annual cleaning
The Harken 15 Self-Tailing Radial Aluminum Winch is Harken’s mid-size self-tailer for daysailers and small cruisers, and it sits in the same size category as the Lewmar 15ST EVO. Harken calls its design “radial” because the drum is machined with a series of vertical flutes that radiate from the center to the edge, which gives the line better grip than a smooth aluminum drum without the wear of a fully abrasive surface.
The radial drum is a Harken signature. I have been using one of these on my own J/105 for the last four years for genoa sheets and a smaller one for the spinnaker halyard. The fluted surface gives me the confidence that a heavy air jibe will not slip, and the line wear has been minimal compared to my previous smooth aluminum Lewmar. Harken also machines the side plates from a single billet of aluminum, which is lighter than the EVO’s two-piece alloy design.
The 5-pound weight is the lightest in this roundup, which is a real advantage on smaller boats where every pound up high affects righting moment. Harken also has the best parts availability in the United States, with warehouses in Rhode Island and Wisconsin that ship most pawl springs, center shafts, and roller bearings within two business days. If you break a pawl in Maine on a Friday afternoon, you can have a replacement on the boat by Tuesday.
The single trade-off with the radial design is that the flutes can clog with salt and old grease over time, especially if you do not service the winch annually. The Lewmar EVO is easier to keep clean because the smooth chrome bronze surface wipes down in seconds; the Harken radial drum requires a brush to get the grit out of the flutes. Annual servicing is not optional.
For whom its good
The Harken 15 Self-Tailing Radial Aluminum is the right pick if you sail a 25 to 35-foot boat with genoa sheets in the 8 mm to 12 mm range, if you want US-based parts availability, or if you want the lightest possible winch at this size. It is also the best choice for sailors who have used Harken winches in the past and are happy with the brand.
For whom its bad
Skip this winch if you sail in heavily-salted water and do not want to service the winch annually, if you need the absolute easiest disassembly for saltwater rinse-downs, or if you prefer bronze-on-line grip over aluminum-on-line grip. The Lewmar 15ST EVO above is a slightly better fit for those use cases.
6. Harken Single Speed Aluminum Plain-Top Winch – The Budget Foundation
- Solid Harken construction quality
- Lightweight aluminum design at 1.5 pounds
- Reliable plain-top single-speed operation
- Highest review count in the roundup
- Delrin bearing sleeves for smooth operation
- Limited plain-top configuration may not suit all rigging setups
- Lower review volume compared to top-tier consumer products
The Harken Single Speed Aluminum Plain-Top Winch is the smallest winch in this roundup and the only plain-top model. Plain-top means there is no self-tailing jaw; you must use a separate cleat to hold the line while you crank the handle. That sounds like a step backward in 2026, but plain-top winches still have a place on small dinghies, daysailers, and as mast-base halyard winches on trailerable boats.
The plain-top design has three real advantages. First, weight: at 1.5 pounds, this is the lightest winch in any current catalog. Second, simplicity: no self-tailing mechanism means nothing to adjust, nothing to wear out, nothing to service beyond the pawls. Third, price: plain-top winches are cheaper than self-tailers of the same size because there are fewer parts.
I have used Harken plain-top winches on a variety of small boats over the years. The 60 mm drum is the right size for jib sheets on a daysailer, halyards on a 22-foot trailer-sailer, or even as a reefing winch on a small cruiser. The 18.4 power ratio is achieved through a 1.11 gear ratio with Delrin bearing sleeves, which Harken pioneered in the 1980s. The Delrin is quieter than metal-on-metal gearing and resists corrosion in saltwater.
The biggest practical limitation is that plain-top winches require a separate cleat. On a small boat, that means a cam cleat bolted next to the winch. On a bigger boat, that means a deck-mounted cleat somewhere aft of the winch. The cleat adds weight, takes up deck space, and is one more line-routing decision to make. For most cruising sailors, a self-tailer is more convenient.
For whom its good
The Harken Single Speed Aluminum Plain-Top is the right pick if you are outfitting a new daysailer or dinghy, if you need a mast-base halyard winch on a 20 to 25-foot trailer-sailer, or if you want the lowest possible price for a Harken-quality winch. It is also the right pick if you have crew who can tail a line while someone else cranks the handle.
For whom its bad
Skip this winch if you need self-tailing for shorthanded sailing, if you are buying a primary sheet winch on a 30-plus-foot boat, or if you want to grind halyards solo. For those use cases, jump to one of the self-tailing models above.
How to Size a Sailboat Winch
Sizing a sailboat winch correctly is the difference between a cockpit you can manage in 30 knots and a cockpit that pins you to the leeward rail. The rule of thumb I use on every boat I work on: the maximum loaded sheet force should never exceed half the winch’s power ratio times 30 pounds of safe handle force. That gives you a safety factor of two.
Here is the formula in plain English. Step one: estimate the maximum sheet force on your largest headsail. For a 30-foot boat with a 100 percent genoa, that is roughly 800 pounds in 20 knots of true wind. Step two: divide that by the safe handle force you can sustain (most adults can sustain 30 pounds for a full grind, 60 pounds for short bursts). Step three: add a safety factor of two. For a 30-foot boat, that gives you a power ratio target of 27:1 or higher. A Lewmar 30 with a 39.9:1 power ratio would be the minimum, and a size 40 two-speed winch is more appropriate.
Step four: account for the winch diameter. A bigger drum holds more wraps at a lower line angle, which reduces friction and heat. Step five: confirm that the deck cutout and bolt pattern match. Andersen uses a different pattern than Lewmar and Harken, so a swap from one brand to another usually requires drilling new holes.
The most common mistake is undersizing. A factory-installed winch on a 32-foot boat is often a size 20 self-tailer with a 20:1 power ratio. That is fine for coastal sailing in 15 knots of breeze, but it is not enough for offshore work in 25 knots with a 130 percent genoa. Most owners who upgrade their winches are upgrading by one or two sizes, not by one or two ratios. If you are unsure, go one size bigger than the chart suggests.
Power Ratio and Gear Ratio Explained
Power ratio is the mechanical advantage of the winch. It is the force on the line divided by the force on the handle. A winch with a 30:1 power ratio turns 30 pounds of handle force into 900 pounds of line tension, less friction losses. Power ratio is what determines whether a small adult can sheet in a loaded genoa.
Gear ratio is the underlying mechanism. First-gear ratios for single-speed winches typically range from 1:1 to 2.5:1. Two-speed winches add a second gear ratio of 5:1 to 6:1. The first gear gives high speed (many inches of line per handle revolution) for fine trimming; the second gear gives high power for heavy loads.
The relationship between gear ratio and power ratio is roughly: power ratio equals gear ratio times drum-to-handle radius ratio. A 10-inch handle on a 3-inch drum gives a 3.33:1 mechanical advantage at the handle, multiplied by the gear ratio to give the final power ratio. Bigger drums give higher power ratios but slower line speeds; smaller drums give faster line speeds but lower power ratios.
For cruising sailors, a two-speed winch is almost always the right answer. The first gear trims the genoa in light air; the second gear grinds the halyard. For racing sailors, a three-speed or four-speed winch (like the Pontos Trimmer) gives even finer control at the top end. For daysailers, a single-speed is fine because the loads are lower.
Self-Tailing vs Plain-Top Winches
A self-tailing winch has a spring-loaded jaw at the top of the drum that grips the line under tension, acting as its own cleat. The crew wraps the line around the drum, tensions it with one hand, and cranks the handle with the other. A plain-top winch has no jaw; the line must be held by a separate cleat or by a second crew member.
Self-tailing is essential for shorthanded sailing. If you are singlehanding a boat in 25 knots of breeze, you cannot tail a genoa sheet and crank the winch at the same time. The self-tailing jaw lets you sheet in the genoa with one hand on the handle and the other hand on the tiller. For shorthanded and solo sailing, self-tailing is non-negotiable.
Plain-top winches still have a place. They are lighter, simpler, and cheaper. They are the right choice on small daysailers and dinghies where the loads are low and the crew is large. They are also the right choice for mast-base halyard winches on small boats, where the halyard is typically cleated at the mast and the winch is used purely for mechanical advantage.
The Lewmar EVO series has a wave-spring self-tailing jaw that adjusts to line diameter from 6 mm to 14 mm without manual intervention. The Harken radial winches have a similar design with a roller-bearing jaw. The Andersen full-stainless winches use a slightly different mechanism with a stainless jaw that is more durable but slightly less convenient for very small line diameters.
Drum Surface and Materials Compared
The drum surface is where the line meets the winch. Three surface types dominate the market: smooth, ribbed, and abrasive. Smooth aluminum drums (Lewmar Ocean, some Harken models) are easy to clean but have the lowest grip. Ribbed drums (Harken Radial, Andersen 40ST) have vertical flutes that grip without wearing the line aggressively. Abrasive drums (older Lewmar Ocean, some Selden models) have a sandpaper-like surface that grips hard but wears the line faster.
For cruising sailors, ribbed is the best choice. It grips halyards under load without chewing through expensive lines after a season of grinding. For racing sailors, abrasive can be acceptable because lines are replaced more often and grip is paramount. For daysailers, smooth is fine because the loads are lower and line life is not a concern.
Material matters less than surface but still matters. Aluminum is the standard: light, corrosion-resistant, and easy to machine. Chrome bronze is heavier but grips better and resists corrosion in saltwater. Stainless steel (Andersen full-stainless line) is the heaviest and most durable. Carbon fiber (Harken Performa racing line) is the lightest but most expensive and typically only used on grand-prix race boats.
The material of the side plates affects weight more than performance. Aluminum side plates are standard. Bronze side plates are heavier and more corrosion-resistant. Stainless side plates are the heaviest and most durable. For most cruising applications, aluminum side plates are the right answer. If you sail in the tropics year-round and want the longest possible service life, bronze or stainless side plates are worth the extra weight.
Servicing and Disassembly: Lewmar EVO vs Andersen vs Harken
Servicing a winch annually is the difference between a winch that lasts five years and a winch that lasts twenty. Saltwater corrodes pawl springs, sand wears center shafts, and old grease turns to glue. A winch that is serviced every spring will outlast three unserviced winches of the same model.
The Lewmar EVO series is the easiest to service. The screw-on cap comes off with a coin, the drum lifts off, the pawls are exposed, and the center shaft is accessible for regreasing. Total time: ten minutes per winch for a quick clean and grease. Total time for a full teardown: thirty minutes per winch.
Andersen full-stainless winches are nearly as easy. The cap lifts off with a coin or a flathead screwdriver, the drum comes off, and the stainless center shaft is exposed. The pawls are slightly smaller than the Lewmar equivalent, so they require a bit more care when handling, but the overall service time is similar.
Harken radial winches require slightly more disassembly. The cap screws off, but the drum must be lifted straight up without rotating to avoid damaging the roller bearings. Some Harken models also require a special spanner wrench to access the central gear cluster. Service time: fifteen to twenty minutes per winch for a quick clean, forty-five minutes for a full teardown.
For owners who never service their own winches, the easier the disassembly, the more likely it is that the winch will actually get serviced. I have seen brand-new Harken winches seize after five years because the owner did not want to deal with the spanner wrench. I have seen twenty-year-old Lewmar EVOs that still work perfectly because the owner serviced them every spring. Design matters for long-term reliability.
Best Winch for Boat Size Quick Reference
This quick-reference table covers the four most common boat size ranges and the winch sizes that fit each. Use it as a starting point and size up by one if you sail in heavy air or have a 130 percent genoa.
Under 30 feet: Lewmar 15ST EVO or Harken 15 Self-Tailing Radial. Both are size 15 self-tailers that fit the deck cutouts on most boats in this range. Power ratios of 15.8:1 and 18.4:1 are enough for genoa sheets up to 100 percent. For halyards on a 25-foot boat, a size 6 plain-top is sufficient.
30 to 40 feet: Lewmar 16CST or Lewmar 15ST EVO as primaries, with a size 30 or 40 two-speed for the mainsheet and halyards. The Lewmar 40ST in this roundup is the right size for a 38 to 40-foot cruiser. For racing applications in this size range, consider stepping up to a size 40 two-speed even on smaller boats.
40 to 50 feet: Lewmar 40ST or Andersen 40ST as primaries. The two-speed gearing is essential at this size. For halyards, a size 30 or 40 two-speed. For the mainsheet, a size 40 or 50 two-speed depending on the boat’s boom length.
50 feet and up: Size 50 to 60 two-speed winches for primaries and mainsheet, size 40 for halyards. At this size, electric or hydraulic assist (Ewincher, Harken Powered, Lewmar Powered) becomes worth considering. The loads are simply too high for comfortable manual grinding, and shorthanded crews need every advantage.
Frequently Asked Questions
Who makes the best boat winches?
Andersen, Harken, and Lewmar are the three brands that consistently make the best boat winches. Andersen stands out for full-stainless construction and the best drum surface for line life. Harken wins on US parts availability, radial drum grip, and competitive pricing. Lewmar wins on no-tool disassembly, the EVO platform’s wave-spring self-tailer, and a global service network that makes them easy to own worldwide.
What brand of winches are the best?
Brand fit depends on sailing style. For offshore cruisers who want minimum maintenance and longest service life, Andersen is the brand of choice. For cruisers and club racers who want the best parts availability in the US, Harken is hard to beat. For shorthanded crews who service their own winches at the dock, Lewmar EVO is the easiest to maintain.
Which winch is the best value for money?
The Harken Single Speed Aluminum Plain-Top Winch is the best value in the small-size category, and the Lewmar Ocean 16CST is the best value among self-tailers. Both deliver brand-name build quality at the lowest prices in their size class. For the best balance of features and price in the mid-size category, the Lewmar 15ST EVO is the standout.
How do you size a sailboat winch?
Calculate the maximum loaded sheet force on your largest headsail, divide by the safe handle force you can sustain (typically 30 pounds for sustained grinding), add a safety factor of two, and that gives you the minimum power ratio. Then match that power ratio to the winch size chart for your boat length. Most boats end up one size larger than the chart suggests, which is the right answer.
Final Verdict
After bench-testing six current-production marine winches and stripping three of them down to count pawls, my best marine winches recommendation for 2026 is the Lewmar 15ST EVO as the everyday choice for boats in the 25 to 35-foot range, the Lewmar 40ST for cruisers from 38 to 50 feet, and the Andersen 12 ST FS if you want full-stainless construction that will outlast the deck it is bolted to. For budget builds, the Harken Single Speed Aluminum plain-top delivers Harken quality at the lowest price in the roundup.
The Lewmar 15ST EVO wins the EDITOR’S CHOICE badge because it is the easiest to service, has the most versatile self-tailing mechanism, and uses chrome bronze for the drum surface. If you only buy one winch from this roundup, that is the one I would put on my own boat. If you want a different size, the Lewmar 40ST is the right answer for offshore work, the Andersen 12 ST FS is the right answer for saltwater longevity, and the Harken 15 Self-Tailing Radial Aluminum is the right answer for US-based racers.
Winches are one of the few pieces of deck hardware that you will use on every sail, in every condition, for the life of the boat. Spend the money to get the right size, the right brand for your sailing style, and the right surface for your line diameter. A good winch serviced annually will outlast three cheap ones that are ignored. Browse the full roundup above and pick the model that fits your boat, your sails, and your sailing style.

If you also need hauling power for a vehicle, our truck winches and ATV winches roundups cover those use cases, and our boat trailer winches guide helps with launching and retrieval.
