Re: Boat features list
TQA's suggestion to list ESSENTIAL DESIRABLE CONTRA INDICATIONS is ideal but don't be scared to look at boats that aren't what you thought you wanted. I "needed" at least 100 gals of water, no saildrive, no teak decks & 37-42' and wanted a center cockpit. Not one of those things is true of my boat and she's still perfect.
If you can find a well-equipped boat, it's often cheaper than adding the gear yourself. So you've got a good plan in figuring out what the boat would cost to buy and refit/outfit for your plans.
