Fred, comments on a few of your items: Fuel seems really high. Using .75 gal/hour I just topped off with 7.1 gals since the beginning of the season and I'm sailing almost every weekend. Bottom paint: unless you pay someone to do it would run 300-600 depending on quality and # of coats. Sail depreciation: unless you really abuse them should be half your #, and I think that's liberal. Routine engine: maybe 100 for filters, oil, impeller, etc. (again DIY) But non-routine repairs could be much larger. One thing you didn't mention is insurance. If financing you'll have to have it and many marina's require it as well. Good luck with you shopping.
