The newest version of the 31 has been
The Tartan 31 is one of the new line of performance cruising yachts from the venerable-and durable--Grand River, Ohio boatbuilder. In the last few years, Tartan Marine has come out with a range of new models, including the T-28, the 3500 and the 4600. A 41-footer is in the works. Both the 28 and the latest version of the 31 are part of the new Piper series, which are marketed in sailaway condition. Tartan has a reputation for solid construction and good workmanship and that's what the 31 is: solid and well put together. The hull is hand-laminated with alternating layers of chopped strand mat and unidirectional E glass. Behind the NPG/ISO gelcoat there's a layer of vinylester resin, which so far appears to provide the best osmotic blister protection available.
