My Seasport is sitting on the trailer and I have a high school kid sanding and doing the bottom paint. (I just had a disk removed, neck fused and a plate put in so I am out of commission.) I have four bunk rails areas that need to be done too. Can't put it in the water and move it over.... not enough room. So here is my thought: The flat edge of the bottom of the boat sits directly above the trailer frame. If I block it up with 7 1/2" of wood blocks it will be sitting on the trailer frame. So I should be able to lower one bunk rail at a time, sand, paint and put them back up where they belong. Anyone see anything wrong with that plan of attack?
