I just bought a Revolution for my wife to pedal and sail. It's great to be part of the Hobie family again. For ease of sailing I realy wanted to have roller furling on the boat however, the friction was to high between the mast and the tube to allow this to work. I believe I found an easy solution to this problem. I wraped the the bottom of the mast and were the mast contacts the top of the mast tube with a layer of self adhesive telflon tape. Additionaly I put a layer of tape (note this tapeis not the same as plumbing teflon tape) at the top of the mast tube. Then sprayed both peices with Mclube Sailkote. Between the lube and application of the teflon the friction was reduced enough to allow easy furling and unfurling of the sail
