With care and some tape you can re-use the shrink wrap the next year. I once got 3 years out of one.
I had a 34 trawler and reused the shrink wrap for years. Was able to put it on myself but it is a lot of work. Can lead to damage to the boat if you don't secure it correctly and repair the damage from year to year. I needed to constantly check on it. Would not recommend it unless you check your boat weekly and repair damage as it occurs.
