Here's a pic of the loading ramp I built using an old 20ft. marine railway, a winch and 8 carpeted 2 by 6's bolts cross ways. At the front, the first 2 by 6, is has dock bumper plastic so that I can sail her up onto the ramp pretty effortlessly and safely.
I bought a dock wheel kit from ebay so that I can roll the whole affair out of the water for winter. I'll store the boat on top of my ramp on shore for the winter with a good poly trap cover.
Launching is a snap. I also secure her with a heavy chain/lock to deter theives. 2 jet ski trailering straps at the stern are atttached to protect her from a bad storm. Had her blow off this ramp during a bad storm last year.
