There's the Ocean Cats but they only made 10 or so and one just
sold,
Maine Cats and they are still in biz and there's a few on YW in
power and sail, The
Lagoon TPIs from the 1990s were made in the US and there's 2 on YW, A few Gunboats were made in the US but they had issues and the Alphas but they had issues too. Endeavor used to be aligned with
Manta and they made a few sail versions but they are mostly
power now I think.
It's only Gems and MCs now which is sad.
