It was built by Moerman in the same time period as when they built Toc-Toc (S&S design 1674) but this one is 3 feet longer and the interior is completely different. The general structure of the two is very close though..
It's unclear as to whether she is actually an S&S design or one that Moerman made "in house" based on S&S drawings they had. Records were not quite as good back then... Either way she is an amazing boat. If anyone has any information on Moerman boats I'd love to get in touch.
