Just what do you actually need?
From where I sit, the Jeanneau Tonic pretty much has all of the bases covered...
Admittedly the forward berth pictured doesn't really exist and, I'm sure, that it's only in the drawings because some clueless guy in a suit decided they couldn't sell a boat with just one dedicated double berth.
Still, it's a boat that a guy six foot five has plenty of room to be comfortable in, a well thought out galley, and, for a boat under 24 feet long, a head of more than ample size... A very livable design.
What's not to like?
