My first tip? Don't do it. If you feel you have to, minimize damage to the ramp. If you have a bunk trailer, learn the speed you need coming into the trailer to get the nose close to the winch and stop. Crank the last foot. If you have a roller trailer you should use the winch. Don't be that guy with his motor at 1/3 throttle churning mud while he goes up to hook his strap. The blowhole power loading creates undermines the end of the ramp and tears off axles if you back past the end. My buddy rocked a prop badly backing away from the blowhole because of the shallow ridge of rocks just beyond the hole. I can't think of a single time that powerloading has been a good look for any boater at the landing. Kudos to all the ramp crews out there. Fixing concrete plank landings before the fishing season is cold work.
