We have just had our yacht vinyl wrapped and we want to keep the topsides protected when hauling out with a travelift. Our topsides have a degree of tumblehome and as a result the slings press on to the hull above the waterline. As the slings take the weight they stretch and move across the vinyl and we have tears in the wrap which we have repaired but want to avoid this problem happening again. Has anyone tried placing fenders on the waterline bottom paint to pad out the slings so they dont contact the hull above the waterline? If so were inflatable fenders used ( our boat weighs 20 tons and we are concerned that inflatable fenders might burst with the side pressure form the slings)? Any other suggestions to protect the vinyl from the sling movement abrasion?
