We thought about shrink wrap when we got our boat, and thought about paying more and more each season as the price of oil (and therefore plastic) rose. We also considered the environmental implications of throwing away that much plastic each year. The setup we use for our J/36 - a wooden frame with canvas tarps- paid for itself (compared to the cost of a single shrink-wrap job) after two seasons . Our canvas does have some worn and torn spots after four years, but not worth taking to the local loft to fix yet. (Winds over 70kts were recorded in storms last winter alone.) We expect another 5-10 years from our tarps. (They''re NOT the blue plastic kind!) Ours is a decidedly low-key setup, but it works for us.
