Re: 1st boat shopping, ~$20k+-, potty, friend capacity, for eventual use in S.Fla - K
well, of course you want to get an OB. that's a given.
As for a cabin of any kind, considering Florida:
First, you don't have to have a cabin to have a head. And i don't think it's wise to have a cabin for the primary purpose of a head. May as well buy an open boat and carry along a portajon. So get those who are in the decision tree to take a look at their needs in this regard. Those who are the type who camp know how to work around these things. Also (and you figure out why) consider if you are doing day trips without docking, overnights at anchor, or trips to destinations (day or overnight) that have bathrooms. You can p anywhere.
Second, get a cabin if you are going to spend the night often on the boat. Otherwise, don't. Consider that you can always stay in the motel at the destination; you aren't usually saving a lot of money by buying a boat you can sleep in instead (neither do the RV people)*.
Third, a cabin divides your boat in half. During the day and while cruising, no one is in the cabin. How big is the rest of the boat for everyone? At night everyone is in the cabin. How big is the cabin for everyone? (you , your wife, the salesman and soemone else from the dealer should spend an hour together in the cuddy doing the paperwork. With the door closed. Feel free to use the head while you are in there. That will cure you.)
*It isn't saving money to buy a $100,000 RV that gets 4 mpg and costs $75 to park and hook up, instead of a $120 motel room and a $15,000 car that gets 30 mpg. You do it for other reasons.
