no excuse is worthy imo. when i was 15 i could park the boat, back the truck down the ramp, put the boat on the trailer and be out of the way in less than 10 minutes all by myself (also the first year i owned the thing). as long as u have a little common sense it shouldn't be a major ordeal..... but if u throw a bunch of kids into the equation, then i'll have to admit that i'm unexperienced lol
