Rope launch or sling
You can rope launch it or have it put i with a sling. Rope launch involves getting it on the ramp chocking the wheels then unhooking from the tow. Securing a good line between the tow and trailer. Pull forward to apply tention. Set brakes then unchock and back down slowly. Be sure the ramp goes deep enough before it stops or drops off underwater. If you dont you will lose the trailer. try www.trailersailor.com
