Been covered on SA a lot on the front page and under multihull anarchy.
The 25' was at the Newport and Annapolis Boat Shows. I believe it's in Europe now doing a boat show tour there (Paris, Dusseldorf, etc).
I outfitted the boat with all of it's cordage (Marlow), so I saw the boat throughout production. The guys that built it (Warren Light Craft) are amazing boatbuilders. The carbon hulls and everything else about the boat are of the highest quality.
They are planning on building a few 25s early 2013, not sure on the timeframe on the 15'.
Very cool boat. The owner Pete is VERY enthusiastic and a great person to be promoting a boat like this. If your interested I would suggest dropping him a line, he's happy to chat about it.
