One way to do it
Launching single handed requires some careful planning. Be sure the boat is ready when you back down the ramp. Be sure the center board is held up, ballast closed, docking pole, pfd, winch line unhooked, and a bow line of 50' or so tied to the tow vehicle. Back it down far enough to float it off of the trailer which may or may not need the extension depending on ramp slope. When it floats free, I board by jumping into my pickup bed, stepping off the tailgate onto the tongue/ladder and onto the bow. It's a stretch but can be done and don't forget to untie the line and take it with you. Start the motor and back it off. Manuevering with only the motor, no rudder, no keelboard, and no ballast is nasty.... so if you can head for some clear water where you can get everthing in place it's better. If you have to dock with only the motor, then take your time and use the pole and any help you can get at the dock. My biggest disasters so far:1. Not securing a bow line to the tow vehicle. Required some Olympic free style swimming.2. Not pulling center board up. Had to board fiddle for 1/2 hour to get the board cleared from the trailer. 3. Motor wouldn't run. I put the rudder down and paddled in. Sculling I think it is?If you have winds and currents it'd be worth hiring someone to help. If the ramp is very busy, then someone will help and move your vehicle just to get you out of there. I have boarded via the swim ladder in warm weather but the boat is 'free floating' whereas from the trailer ladder, it's held untill I actually climb aboard. It's possible to not even get your feet wet, believe it or not. The boat should be floating so a 5hp motor is plenty.... don't try to power off the trailer or all the bottom paint stays on the bunker boards.My topping lift is just tied at 'full down' position and throwing a loop or two around the boom will hold it up. The rope was never long enough to go down thru the boom to the little jam cleats but if you have the rope that works OK. It's inconvenient when removing the boom, though.KenS/V Wouff Hong
