The PS25 is a double-ender with an outboardrudder and does not have standing headroom (unless you happen to be 4 feet tall).
PS25 is designed after the East Coast Cod fishing boats of the 19th century.
Nonetheless, the PSC25 has done some great voyaging. Google "tiny bubbles" and you can find a couple 20somethings who took one all over creation. There is also a yahoo group dedicated to the 25.
I agree on the Orion. Nice boat. For some reason (perhaps that it is not a crealock boat) it is sort of the black sheep of the PSC family. I figure that just makes it more affordable (significantly cheaper than a Dana). I particularly like the dinette version.
