You first have to set a what you want out of a boat list?
ie: fishing, overnighting, skiing, tow toys, diving and all the other things we do on water.
An example is my boat 27' deep vee for speed, with sleeping for 2 or 3, cooker, fridge, wc and other niceties, tows toys easily and makes a lovely family boat but all those cruising bits compromise the fishing space. I had to choose a boat this way to justify the expense to Mrs Burt.
Every boat is a compromise some are more so than others.
Make your list and narrow your choice then go looking
