What I don't understand is why you're going through all of this when you're not even sure the boat is worth buying.
That is exactly what I am trying to do. If my sails will last me a few years i can get nice, new more efficient ones. If my hull actually does need to be re-caulked, then i will take that into consideration. If during the survey, i find out that more than just a couple planks need replacing, then i wont buy the boat. All these threads are here in hopes of figuring it out.
