Manual Trailer Winches 15 to 1 Wide Body from Trojan redefine marine winching with a closed-top, wide-body design that delivers steady control and rugged dependability. The pinnacle of our manual winch lineup, the 15:1 winding option, is built to handle larger boats and heavier loads while maintaining smooth operation and long-term reliability in saltwater environments.

Designed for real-world use on the water, these winches combine a galvanised steel housing with high-grade stainless steel components. That combination delivers exceptional corrosion resistance and minimal maintenance, so you spend more time on the water and less time servicing your gear. Whether you prefer winch rope or winch wire, Trojans’ wide-body approach accommodates different setups, ensuring you get the right balance of strength, control, and ease of use.

Key features that make a difference

• Wide-body stability for better load control and effortless handling on trailers and docks.
• Marine-grade durability with galvanised housing and stainless steel parts to resist corrosion in harsh coastal environments.
• Flexible winding options available from 1:1 up to 15:1, including mixed ratios like 3:1 & 1:1 and 10:1 & 5:1, to match boat size and pulling needs.
• Choose your media with or without winch rope or wire, so you can tailor the setup to your boat and preference.
• Extensive spare parts and dedicated service kits keep downtime to a minimum and extend the life of the winch.
• Closed-top design protects internal components from the elements, contributing to longevity in marine use.

Why this matters for boaters and trailer setups

If you’re trailering larger vessels, docking in saltwater, or routinely launching and retrieving in challenging conditions, the 15:1 Wide Body wins with more controlled, powerful winsching and a longer, more forgiving rope/wire path. The wide-body design distributes load more evenly across the drum, reducing wear and helping you pull smoothly even when the boat weight sits near the maximum rating. The availability of both rope and wire configurations, plus the option to pair with different rope lengths and diameters, means you can fine-tune the system for your specific hull type, trailer geometry, and deployment environment.

Compared to lighter or narrower winch designs, this range offers higher maximum pulls (up to 1500 kg in the 15:1 configurations) and more versatile winding options, so you can choose the exact ratio that matches your boat’s weight, launch ramp incline, and desired control level. The combination of galvanised chassis, stainless steel components, and the closed-top construction minimizes maintenance while maximizing longevity on saltwater boats and trailers.

Practical tips for optimal performance

• Choose a winding option that provides a comfortable balance between speed and mechanical advantage for your boat’s weight and the trailer slope you commonly encounter.
• Inspect serviceable components with the included service kits periodically to prevent wear from turning into downtime.
• Store the winch in a dry, protected area when not in use to preserve the integrity of the rope or strap and the drum mechanism.
• Use the appropriate rope size or strap with the corresponding model to maintain safe pull loads and prevent slippage or overloading.

With Trojan’s 15:1 Wide Body Manual Trailer Winches, you’re choosing a marine-grade solution built to endure the rigors of regular trailer launches, salt spray, and heavy-duty loads—backed by a broad ecosystem of spare parts and service kits to keep you moving when it matters most.
