I'm going to change out the centerboard uphaul on my '98 H240 before launch this spring. The only lift I have access to locally is stationary, and has straps that connect to a center block rather than on each side like a travelift. There are 2 blocks, one for each strap. Will this type of lift exert too much pressure on the rubrails or deck by pulling from the center? I asked the dealership about putting a long board across the deck at each strap to hold them off the rubrail, but they were not excited about that idea for safety reasons. Anyone used this type of lift with a 240 or 260?
