Make a must have list, a nice to have list & a not fussy about list.
Stick to the lists & the potential models get whittled down very quickly.
Intend to drycamp? then you will need a large freshwater tank, say 80 gal minimum. Anything less than 80gal gets dropped from the potential list. Alot of them.
Want plenty of galley space? Won't be restauranting it much? Then you need an island or U shaped galley. That cuts out more.
Got a length or weight limit? Kerchop!
Got a build standard you must have? This one could eliminate a bunch of builders.
Doesn't take long. You will be down to a few models in no time.
