The 25:1 Gear Advantage
How do you lift a 400 lb boat with one hand? Physics.
The heart of our Manual System is a custom-engineered worm gear reduction mechanism with a 25:1 ratio.
- What this means: For every 25 turns of the handle, the drum turns once. This multiplies your input force significantly.
- The Result: An average adult can safely hoist a fully loaded tender (dinghy + motor + fuel) from the water to the stowed position with minimal physical exertion.
- Safety: It features a self-braking mechanism that prevents the handle from spinning back, ensuring total control during launch and retrieval.
Why Choose the Manual System?
100% Reliable (No Power Needed)
Batteries fail. Hydraulics can leak. A gear system just works.
For captains who cruise to remote locations (Desolation Sound, The Bahamas) or sailors with limited battery banks, the Manual System offers ultimate peace of mind. It is always ready to launch.
Lightweight Design
Weight on the transom affects your boat’s trim and fuel economy.
- SeaWise Manual System Weight: ~100 lbs (45 kg).
- Compared to Hydraulics: It is nearly half the weight of a hydraulic setup, making it the perfect choice for weight-sensitive vessels or swim platforms with lower load ratings.
Premium Build Quality
Just like our electric models, the Manual System is built to outlast your boat.
- Case: Durable Bronze alloy.
- Gears: Hardened Steel and Bronze.
- Structure: Electro-polished 316L Stainless Steel.
- Cable: Marine-grade stainless steel aircraft cable.
