The design is very thought-through, and shown by this article in Duckworks Magazine by their creator Nick Newland of Swallow Boats. I particularly appreciate the emphasis on ergonomics. Home boat designers tend to focus on the lines, aiming for the ultimately fast hull, but in my opinion you can get much more performance simply by making things comfortable for the rowers.
They are not being made any more, but Swallow boats has a hull in the mould that is informally for sale. And Mike Phillips in Wales has a second-hand one on the market.
Mike is a non-rowing angler, so the Teifi's long slim shape is really not suitable for him at all. And he uses an outboard jury-rigged on the stern (horror!).
So he's selling it, on its road trailer, with stretchers and rudder but no blades, for £2,250. If you are interested ring Mike on 01239 820 228 or email email@example.com.
