trailer loading

Last week I had a difficult time loading my 18 mag on to my trailor . I try to avoid submerging my trailor wheels as I back into the lake. This presents the problem of lifting the hull on to the rollers at the rear of the trailor then pulling the boat forward . Rolling the boat forward past the balance point is difficult so.......BRIGHT IDEA HITS ME.....why not spray silicone on to the surface of the rollers just before loading? Worked super! The hulls just slid over the rollers like skates on ice. PS If this presents a problem with your local environmentalists, maybe using a squirt bottle of "BIODEGRADABLE GREEN" liquid soap would be effective. Just a suggestion!!!!! dj
