Buying Used Marine Gear

Chandlery Guide · Gear & Equipment

The cruising community runs a substantial parallel economy in used marine equipment, and for good reasons: marine gear is expensive, the chandleries charge full retail, and a significant portion of used gear is in perfectly serviceable condition — sold because someone upgraded, refitted to a different configuration, or is selling the boat. Understanding what is worth buying used, what requires new certification, and where the market actually operates gives you access to a genuine cost advantage on a cruising budget.

Where the Market Lives

The cruising community used gear market is distributed across several venues, each with different strengths. Facebook has become the dominant platform for marine used gear in recent years, with the Cruisers Forum Buy/Sell/Trade group, Women Who Sail B/S/T, and a proliferating network of regional groups (East Coast Sailing B/S/T, Pacific Cruisers, Caribbean Sailors, and similar) that offer locally-relevant listings. The advantage of these groups is the community context: sellers and buyers often have shared connections, reputation travels, and the specific-use commentary ("replaced this with a larger furler, was in good service for four seasons") is usually honest.

Craigslist, filtered to marina-adjacent zip codes, surfaces a different market: local sailors selling gear that may not have the bluewater-community audience. Boatyard listings, marina bulletin boards, and local sailing club classifieds are all worth checking in your home region. eBay Marine covers the longer tail of specific hardware — the discontinued Harken block size, the older Furuno instrument, the specific Autohelm tiller pilot — where the items are uncommon enough that national search reach matters. Boat Parts Market is a dedicated platform with a reasonable used marine catalog.

The best source for specific hardware is a boat being stripped, decommissioned, or sold out of a boatyard. Ask the yard manager directly: "Is there a boat coming out that I could approach the owner about buying hardware from?" Boats being cleared for sale, total-losses being parted out, or owners upgrading wholesale are all situations where good gear is available at steep discounts, often to whoever asks first. The informal boatyard network is the part of the used market that does not appear online.

What Is Excellent Used: Stainless Hardware

Stainless steel deck hardware — winches, blocks, clutches, clutch banks, chainplates, bow rollers, cleats, tracks, and traveler systems — is among the best used marine gear available. Stainless hardware has a long service life when properly maintained, the materials do not degrade invisibly with age, and a thorough inspection gives you genuine confidence in what you are buying. The inspection protocol for stainless hardware is straightforward: look for surface corrosion (brown rust staining that can indicate crevice corrosion developing beneath), physical deformation or cracking from overloading, worn bearing surfaces in blocks and blocks, and thread condition on fasteners and turnbuckles.

Minor surface rust on stainless hardware is often cosmetic — treatable with stainless polishing compound or oxalic acid — rather than structural. Crevice corrosion at joints, cracks in the metal, or visible deformation are disqualifying. Hardware that passes visual inspection should be priced at 30 to 50 percent of new for excellent condition; negotiate toward the lower end if there is any cosmetic work needed.

Anchors and chain are excellent used purchases when properly evaluated. A Delta, CQR, Rocna, or Mantus anchor in good condition — no significant corrosion, no bent flukes, no cracked shank — is as good as new. Chain requires a chain wear gauge test: lay the chain over the gauge appropriate to your chain size; if the chain has elongated beyond the wear limit, it should be retired regardless of apparent condition. Priced right, a lightly used chain and anchor combination is one of the better used gear deals available.

What Is Excellent Used: Instruments and Electronics

Marine electronics — chartplotters, VHF radios, depth sounders, wind instruments, AIS receivers, autopilot control heads — can be excellent used purchases if functionality is verified before buying. The key precaution is testing: any electronics purchase should come with a demonstration that the unit powers on, displays correctly, and communicates with other system components if network-dependent. A Garmin chartplotter that boots correctly and displays charts is the same device regardless of whether it is new or five years old; the maps can be updated, the software can be updated, and the hardware has no mechanical wear components that degrade in normal use.

The risks with used electronics are water damage (which may not be immediately apparent), missing mounts and cables (which can be more expensive to replace than they appear), and older units that are no longer supported by manufacturer software updates. For AIS transponders and VHF radios with DSC, verify that the MMSI programming can be reset to your vessel's number — some older units have MMSI locked in a way that prevents reassignment.

What to Never Buy Used: Safety Equipment

Life rafts, EPIRBs, PLBs, flares, and lifejacket inflation systems must be purchased new, with current certifications, from reputable retailers. This is not a conservative recommendation — it is the correct position when the tradeoff is weighed honestly.

Life rafts carry service requirements: inspection and re-certification at specified intervals (typically one to three years depending on manufacturer and service station), with hydrostatic release replacement and CO2 cylinder certification included. A used life raft without documented current service history has an unknown inflation system, unknown container condition, and unknown survival pack contents. The $500 saved on a used life raft is real; the risk of an uninflated raft in a sinking is not hypothetical. Buy new, from a reputable retailer, with the service interval documented, and service it on schedule.

Flares have mandatory expiry dates that are legal requirements in most jurisdictions — expired flares are not merely less reliable, they are non-compliant. EPIRBs and PLBs require current battery certification and registration — a used EPIRB that is not registered to your vessel, or whose battery is past service date, provides neither legal compliance nor reliable function. The cost of new flares and EPIRB battery service is not significant relative to the consequence of having non-functional safety equipment when it matters.

Lifejackets require inspection of the inflation mechanism, the oral inflation tube, the CO2 cylinder (verify weight against specification), and the arming pin and water-activated cartridge. Rearming kits are inexpensive and should be fitted whenever a lifejacket has been inflated or when the cartridge is past its service date. Used lifejackets in unknown service history should be treated as requiring full rearming before relying on them — factor that cost into the evaluation.

Evaluating Used Sails

Sails can be excellent used purchases or worthless, and the difference is visible with proper inspection. The first test is to hold the sail up to bright light and look through the fabric: woven dacron shows no significant light transmission in a strong sail and increasing light through areas where the fibers have fatigued and thinned. Laminate sails (mylar and composite constructions) should be checked for delamination — separation between the laminate layers that appears as cloudy bubbles or crinkling in the film.

UV degradation on the UV-protection strip along the leech and foot is a common and critical failure point for roller-furling headsails. Check the strip for brittleness, cracking, and color fade — a heavily degraded UV strip means the underlying sail fabric has likely received significant UV damage as well. Batten pockets should be inspected for reinforcing integrity, as torn pocket ends are where sail damage typically propagates. The headboard patches and clew reinforcing on older sails are worth examining; repair work on these areas is expensive relative to the sail's used value.

Sails with cosmetic staining, minor repairs, or minor wear at high-load points are usually worth buying at appropriate discounts if the base fabric is sound. Sails with structural delamination, multiple areas of light transmission, or failed UV strips are typically not worth the cost of repair unless the sail is extraordinarily large and expensive new.

The Winch Rebuild: Maximum Value in Used Hardware

The winch rebuild opportunity deserves specific attention because it is one of the clearest value propositions in used marine gear. A Lewmar 46 two-speed self-tailer that costs $600 to $800 new can be purchased used for $150 to $250 in unknown service condition, taken apart in an afternoon, inspected, fitted with a $30 pawl and spring kit, repacked with fresh grease, and reassembled with performance equal to new. The procedure is not technically demanding — both Lewmar and Harken publish illustrated service instructions — and the tools required are standard.

The inspection during disassembly reveals the actual condition: worn pawl springs are the most common issue and the cheapest fix; chipped pawls should be replaced; worn needle bearings show scoring and loss of roundness; drum bearing surfaces show galling or scoring in heavily worn winches. A winch that passes inspection with fresh pawl springs and grease will perform correctly. A winch with damaged drum surfaces or cracked housing is worth less than it appears.

Pricing Used Marine Gear

Used marine gear has no standard price guide equivalent to automotive blue books, which means both sides of a transaction are working from incomplete information. The practical approach is to look up the current new price from a chandlery, then offer 30 to 50 percent for excellent used condition, negotiating down from there based on the actual condition found in inspection. Excellent condition means: fully functional, no corrosion or damage, complete with all original components, clean and ready to install.

The "original box, never used" premium that sellers sometimes ask for is rarely justified at close to new prices. Marine gear sitting in a box for several years has potentially aged gaskets, seals, and lubricants — the assumption that uninstalled means unused-condition is not always correct. More importantly, the market for used marine gear is thin enough that patience rewards buyers: if the price is not right, the correct move is to wait, not to pay new-adjacent prices for used equipment.

The exception is when you need the specific item before a departure date that cannot move. In that case, the used market's timing benefit (available now, locally) justifies a price closer to new than patience would otherwise produce. Knowing the difference between a negotiating position and a genuine constraint is the more important skill.

Frequently Asked Questions

What safety equipment should never be purchased used? Life rafts, EPIRBs, PLBs, and flares should never be purchased used under any circumstances. Life raft serviceability cannot be verified without opening the canister — a procedure that destroys the gas seal and requires professional repacking at significant cost. EPIRBs and PLBs may carry a previous owner's registration, and the MMSI and vessel data embedded in a Category I EPIRB are not easily reset by a buyer; a rescue triggered by a previous owner's registration wastes Coast Guard resources and may not reach you. Flares have mandatory expiry dates enforced by law; a flare past its date provides no legal or practical value.

What is the correct price range for a used Lewmar 46 winch and what condition checks matter? A Lewmar 46 two-speed self-tailing winch sells new for $600–800; a used example in excellent condition should be priced at $150–250 — approximately 25–30% of new. The condition check involves removing the drum and inspecting the pawls and springs (the small ratchet mechanisms that lock the drum in one direction) for wear and corrosion. Broken or corroded pawls cause drum slippage under load. The self-tailing arm should grip wire firmly without slipping. A winch that passes these checks and turns smoothly is a sound purchase; one with sloppy bearings or broken pawls needs a rebuild kit before use.

What is the correct test for used anchor chain wear? Chain wear is measured with a chain wear gauge (available for under $20) that spans a set number of links and measures elongation. Standard proof coil and BBB chain wears at the pin-and-link contact points, elongating the chain as material is removed. A chain that measures 10% elongation is at end of life and should not be trusted for offshore anchoring. Alternatively, lay 12 links of the used chain alongside 12 links of known-new chain of the same size — visible elongation indicates wear. Heavily rusted chain that cannot be measured through corrosion is not trustworthy regardless of apparent remaining metal.

What is the practical discount range for used marine gear in excellent condition? The realistic price for used marine gear in genuinely excellent condition — lightly used, no corrosion, all original parts present — is 30–50% of the current new retail price. Heavily used but functional gear in good condition falls in the 15–25% range. Anything priced above 60% of new offers no meaningful saving over buying new with a warranty. The key caveat is that 'excellent condition' in a marine environment means inspected in person: photos cannot reveal internal corrosion, stripped threads, or UV-degraded plastics that look intact in images.

What concern should buyers have about used AIS transponders and MMSI numbers? An AIS Class B transponder carries a programmed MMSI number that is registered to the original owner's vessel. Using a transponder with someone else's MMSI means your vessel broadcasts the previous owner's vessel name and call sign to every ship in VHF range — a problem in a collision or distress situation where SAR assets respond to the wrong vessel description. Most AIS transponders can be reprogrammed by a marine electronics installer, but some manufacturers restrict MMSI changes to one-time programming. Verify the reprogramming procedure and cost before purchasing a used AIS unit.

What categories of used gear offer the best value for budget sailors? The best value categories for used marine gear are: mechanical hardware (winches, blocks, clutches, travellers — all inspectable and rebuildable), ground tackle (anchor and chain, chain testable with a wear gauge), non-electronic instruments (mechanical compasses, handbearing compasses, depth sounders with transducers), and canvas items in good condition (dodgers, biminis — inspectable visually for UV degradation and seam integrity). Electronics are riskier because internal failures are not visible, software may be outdated, and transducer compatibility must be verified. Structural items (chainplates, mast hardware) should only be purchased used with access to the full service history.
