A real small builder. I don't know if they keep up with demand but 4 boats sounded like they were buried in work.
I heard plans may be in the works for an owner built model. There aren't that many people that buy sailboats new, especially today. That may be why many small builders are doing fine, they only supply so many. The "old" mass produced boats of decades ago had to be built in bigger numbers to make any financial sense.
In clean warm swimmable shoal water like your sailing grounds, a boat like the Presto would be hard to beat for me. The idea you can get out and pull it around with you to shores and anchorages is appealing, not to mention they fly.
