I'm needing to replace the carpet on my bunks. Can anyone tell me how to raise the boat safely off the bunks? I have a 17'6" Express with a 50 hp motor. Not sure of weight with 12 gal. fuel cell and 4 batteries. I need to get the boat up at least 4" off the bunks.I thought about taking it to the lake, launching, and doing it in the parking lot if nothing else.Also, where would be the best and cheapest place to get carpet for the boat?My bunks are about 6' long and are 2x6's.
