What do you sail now? There are 3 boats in your sig. What other boats have you sailed that you appreciate their performance? Sounds like you want a boat that can plane, and most planers aren't going to have much room below.
That is probably the best way to answer the question. I have sailed a Tartan 10, which for a big boat, I remember sailing very well speed wise. Truthfully, the only thing preventing me from looking seriously at one is the 9+ foot width and the permanent keel. Its bigger than I need, but could really be OK if it was trailerable. I also sailed in a Mac, I think it was ~25 footer. I remember it being kind of slow.
I guess, my descriptions are coming in halfway through the story. The absolute needs are:
Cabin with head - I have digestive issues that can require an immediate solution, no time to sail back to a shore.
The speed and family friendly go somewhat hand in hand. The rest of the family is not as patient is I. The desire for a cabin is more height than over all space, as one does need to live down there, but you need to be able to nearly stand up to get your clothes/suit back on after using the head. I get into a delicate balance of desires here, as the DW has perceptions about what she would be willing to spend money on - spend a bunch of money and can't even sit up in the cabin? - that may not go over very well.
I would view the Beneteua 210 or 235 look almost - maybe - kind of marginally OK. They are rated to do 6.5 knots in a 10 knot breeze. The problem is then comparing to other boats. The PHRF is between 190 and 210. So how much slower is a boat that is rated between 240 and 250? Will I notice that much difference?
The Hobie was great speed wise, but was a little small for 4 people, and not porta-potty ready. I don't sail it any more, one of the pontoons was damaged and repaired by someone else and it no longer sails right. The repair added a bunch of weight. So it is just a yard ornament. The phantom is a project boat, with hopes to be used for a 100 acre lake and to tow behind my motorcycle.
There have been some suggestions here, but it is difficult to compare, as I could not find any ratings for most of the boats given.
