Yeah a couple boats had them at our old east coast club ramp..
Big bucks thu... way out of our pocket range
They are not light either with all the hydraulics and stuff.
Also CCA power requirement.. from memory was bigger than the battery in my old low duration SB chevy cranking 220lbs.. and bigger than our 150 V6 outboard.
Besides that apparently they cant be set up for keel trailers (??)
A question .. digres here.
Launching.. one unhooks the winch from the bow, and slides the boat off.. and someone holds a bow rope (painter ?). Go park up.. then pull the winch hook to rear of trailer ready for fast retrieve..
Have often thought about remove shackle, leave winch hook attached, and push the boat off.. it stops at the end of the winch rope, then drive forward a few meters pull boat into shallows , un hook winch and secure painter.. bow rope go park.
Anyone actually done this?
Why should it not be done?
Maybe have a 10mm x 500mm bungee section?
