Dinger Boat Plan

Design 509 Brasil and Mackinac Classes

Originally designed for a group of South American yachtsmen and known as the Brasil Class, this was a very successful design. Notable is the winning of the first, second, fourth and fifth places in the Buenos Aires - Rio De Janeiro race of 1953.


The design was developed into a class for North America and called the Mackinac Class. Built by Fisher Boat Works of Chicago, eight initial boats were built just after the war and all named for Santa Claus reindeer. The boats were identical with the exception of sail area, Brasil being for heavy air and Mackinac for light air.

Here are the plans. I can tell without looking that K. Aage Nielsen is the draftsman.
