SeaSense Hand Winches & Parts

SeaSense Hand Winches & Parts: Built for the Water's Edge

When it comes to loading and securing a boat on a trailer, the hand winch is often the most hands-on piece of equipment in a boater's toolkit. SeaSense has been engineering reliable marine and trailer products since 1984, and their approach to hand winches and winch parts reflects decades of real-world refinement. For boaters who want dependable, corrosion-resistant gear that holds up in harsh marine environments, SeaSense delivers purpose-built solutions across a range of capacities and configurations.

A Winch Lineup Built Around Capacity and Corrosion Resistance

SeaSense offers hand winches spanning a broad capacity range — from compact units suited for personal watercraft all the way up to heavy-duty models for larger boats. Their Zinc Plated PWC Trailer Winch is a standout entry-level option, featuring a 4.1:1 gear ratio and solid gear construction for smooth, controlled cranking. It includes a two-way ratchet with free spool and comes with a 2" x 12' strap with bow loop and hook — everything needed for a complete setup right out of the box.

Stepping up in capability, the SEACOAT line represents SeaSense's premium winch tier, featuring specialized coating technology designed to resist the corrosion that is inevitable in saltwater and humid marine environments. The SEACOAT Dual Drive Trailer Winch and SEACOAT Trailer Winch (rated up to 2,500 lbs) are engineered for boaters who regularly trailer in demanding conditions and need gear that won't degrade season after season. The lineup also includes a Trailer Winch with EZ Shift, which simplifies gear engagement for single-handed operation at the ramp.

Essential Winch Parts and Accessories

Beyond complete winch units, SeaSense recognizes that replacement parts and accessories are just as critical to a functional trailer setup. Their Replacement Winch Handle offers a universal fit — compatible with SeaSense winches and many other brands — and features a corrosion-resistant, ergonomic power-grip design with mounting hardware included. It's the kind of practical part that can rescue a launch day when an old handle finally gives out.

SeaSense also supplies a full range of winch straps to complement their winch units. Standard polyester webbing straps feature zinc-plated safety hooks and are available in multiple lengths (12', 15', and 20') with a working load rated up to 900 lbs. Heavy-duty versions step up to 8,000 lbs breaking strength and a 2,400 lb working load, sized for larger vessels and 2,500 lb winches. Winch covers made from ABS plastic round out the parts catalog, protecting gears from the elements and helping prevent accidental injuries when the winch is not in use.
