The Telstar is one of the more liveable boats out of the small folding trimarans. The corsairs are not liveable, until you get up to a Corsair F31, as you can't stand up inside one until that point, as they have less than five feet of head room, where the Telstar has six feet of head room.
It might be a bit tight for two people, as trimarans have less space than the same length monohulls. You might be better off with a catamaran, like the Gemini 105
, the TomCat 9.7
, or the Maine Cat 30
. These boats will present you with a lot more living space, and should prevent you and your wife from going psychotic from the limited room.
If you have any specific questions, drop me a PM. Most of the sailors on this site are monohullers. I am not.
If the marina has good facilities, then it might be possible to pull it off on a F31 or a Telstar 28...but I don't think the missus would be happy. She'd probably be happy with any of the cats I mentioned.
BTW, the Gemini 105 and the TomCat 9.7 are both about $150,000 new.
The Gemini is the narrowest of the boats, but the longest, with a beam of 14' and LOA of 33' 6". The MaineCat 30 is the shortest, but the widest, with a beam of 18' and LOA of 30', and the TomCat 9.7 is in the middle, with a beam of 16' and a LOA of 32'. The Gemini might fit in a single slip, where the other two are probably too wide to do so.
The draft on all three boats is fairly comparable, with the Gemini being the deepest at 5' 6" and 18" (board down and up) to the TomCat at 5' and 16", and the MaineCat at 5' and 2'.
Of the three I would recommend against the MaineCat as it is the most expensive, has the deepest board up draft, and is considerably wider than the others. It will probably have the worst sailing performance of the three, being wider and shorter than the other two. I don't see any particular advantage to this boat, over the other two that would make it worth the 16% price differential.
