Anodized aluminum is the lightest and least expensive sailboat winch body; bronze and chrome-plated bronze run 35-45% heavier at the same size but wear and age differently over decades of use. MAURIPRO stocks the same Antal Plain Top winch in all three finishes, so you can size the body material to your deck load and your maintenance tolerance, not just the brand.
Most winch shopping starts and ends with size and speed — Size 16 or Size 30, one-speed or two-speed — and the body finish gets picked on looks alone. That's a mistake on two fronts: the finish changes the weight sitting up on your coachroof or coaming, and it changes how much polishing, re-anodizing, or plating touch-up the winch will need ten and twenty years from now.
This guide is for the mid-size cruiser (roughly 30-45 ft) choosing new primary or secondary winches, or replacing an aging winch and deciding whether to match the original finish or switch. We pulled real weights, prices, and gear specs for the exact same Antal winch body sold in aluminum, chrome, and bronze so the comparison is apples-to-apples, not brand-to-brand.

Why does winch body material matter?
The winch mechanism inside — pawls, gears, drum bearing — is generally the same regardless of the outer body finish; what changes is weight, corrosion behavior, and how the finish ages. On a mid-size cruiser running two or three primaries plus a mainsheet winch, the cumulative weight difference between finishes adds up in exactly the place you don't want it: high and outboard, on the coachroof or cockpit coaming, working against stability. Below decks or dockside, that same weight difference is irrelevant — which is why the "right" material depends on where the winch sits and how much you care about shaving pounds versus keeping a classic look.
How much heavier is a bronze winch than the same aluminum winch?
At Size 16, Antal's bronze and chrome-plated-bronze bodies both weigh 6.39 lb (2.90 kg) against 4.41 lb (2.00 kg) for the anodized aluminum body — a 45% weight increase for the same winch, same gear ratios (1:1 and 2.1:1), and same 7.3/14.5 power rating. The gap holds at larger sizes too: Antal's Size 30 bronze body weighs 8.37 lb (3.80 kg) against 6.17 lb (2.80 kg) for aluminum, a 36% increase. Multiply that across three or four winches on deck and the aluminum-vs-bronze choice becomes a real, if modest, stability and windage consideration, not just an aesthetic one.
Why do chrome and bronze winches of the same size weigh exactly the same?
Because a "chrome" sailboat winch is, mechanically, a bronze winch — chrome is a thin plating applied over the same solid bronze casting, not a separate lightweight alloy. That's confirmed directly in Antal's own Size 16 specifications: the chrome and bronze versions share the identical 6.39 lb (2.90 kg) weight, the same gear ratios, and the same power rating. The only real difference is the surface: bare polished bronze develops a green patina if left unpolished, while chrome plating stays bright with far less upkeep — until the plating itself chips or wears through at a high-friction point, which exposes the bronze underneath and can eventually need re-chroming.
Which material resists saltwater corrosion best?
Bronze is the traditional standard for marine hardware because it resists the pitting and crevice corrosion that can affect stainless steel in a stagnant, oxygen-starved saltwater film — the same reason bronze shows up in propellers, seacocks, and older deck hardware that's still serviceable decades later. Anodized aluminum also resists saltwater corrosion well as long as the anodized layer stays intact; once that layer wears through at a contact point or gets scratched to bare metal, the exposed aluminum is more prone to oxidizing than bronze would be in the same spot. In practice, all three finishes are marine-grade choices sold specifically for this use — the differentiator is long-term appearance and touch-up maintenance, not whether the winch will survive a saltwater environment.
How do you maintain each finish?
Bare bronze wants regular polishing if you want to keep the bright look; skip it and the winch develops a green-tinged patina that's cosmetic, not structural, and doesn't need to be treated as a problem. Chrome-plated bronze holds its shine longer with less routine polishing, but a chipped or worn plating spot should be watched — it won't spread on its own, but it's the one place on a chrome winch that can eventually need professional re-chroming. Anodized aluminum needs the least routine polishing of the three; its main maintenance point is avoiding abrasive cleaners that can dull or wear through the anodized layer faster than normal handling would.
Which should you choose for your boat?
If you're outfitting or re-sizing winches on a performance-minded cruiser and weight aloft or on deck genuinely matters to you, anodized aluminum gives you the same mechanism at the lowest weight and the lowest price of the three. If you're restoring or matching hardware on a traditional or classic-styled yacht, bronze or chrome-plated bronze keeps the period-correct look and the long service life bronze is known for, at a real but modest weight and cost premium. There's no wrong answer between chrome and bare bronze specifically — that choice is purely about how much polishing you're willing to do versus how much shine you want to maintain.
Expert notes
From our rigging bench: we see more sailors regret going all-aluminum for pure weight savings and then miss the classic look on an older boat than the reverse — if your boat already has bronze deck hardware, cleats, or portlights, matching new winches to that finish usually reads better than introducing black anodized bodies alongside older bronze fittings.
We also point out that "chrome" and "bronze" versions of the same winch are functionally identical below the surface — if you're deciding purely on mechanism, gearing, or power rating, that decision is already made for you at a given size; only the finish is left to choose.
Common mistakes
- Assuming a chrome winch is a different alloy from a bronze one. It's the same bronze casting, plated — weight and gearing are identical to the bare bronze version at the same size.
- Picking finish by boat color scheme alone. Weight aloft and long-term maintenance (polishing versus re-anodizing versus re-chroming) matter more than matching trim.
- Ignoring the cumulative weight of multiple winches. A 35-45% per-winch weight difference is minor for one winch and real for four.
- Treating bronze patina as a defect. An unpolished bronze winch turning green is cosmetic aging, not corrosion damage or a functional problem.
Frequently asked questions
Is a bronze sailboat winch heavier than the same winch in aluminum?
Yes. At Size 16, Antal's bronze and chrome-plated-bronze bodies weigh 6.39 lb (2.90 kg) versus 4.41 lb (2.00 kg) for the anodized aluminum version of the same winch — a 45% increase. The gap is similar (36%) at Size 30.
What's the difference between a chrome and a bronze sailboat winch?
Mechanically, nothing — a chrome winch is a bronze winch with a thin chrome plating over the same casting, confirmed by identical weight and gear specs between the two finishes at the same size. The difference is purely cosmetic and in long-term upkeep: chrome stays bright longer with less polishing, while bare bronze develops a patina if left unpolished.
Does chrome plating wear off a sailboat winch?
It can, at high-friction contact points over years of use, which exposes the bronze underneath. That's a cosmetic and touch-up issue, not a functional failure, and heavily worn plating can be re-chromed.
Which sailboat winch material resists saltwater corrosion best?
Bronze, chrome-plated bronze, and anodized aluminum are all sold as marine-grade finishes for this exact use and all resist saltwater corrosion well under normal service. Bronze is the traditional standard for long-term marine hardware; anodized aluminum depends on the anodized layer staying intact at contact points.
