The Thistle was designed by Sandy Douglas in 1945 as a 17 foot, plumb bow, one design sailboat that could be raced by two or three, or day sailed comfortably by as many as six people. Thistles are very light because they are completely open, having no deck to add weight. This open design allows it to carry more people comfortably while making it extremely fast. Its round bottom hull makes it very responsive & exciting to sail.

Come join us in one of the most versatile, user-friendly sailboats on Geist. The Y-Flyer's flat hull shape and hard chines provide a stable sailboat that is easy for people of all ages and sizes to sail. The Y-Flyer is extremely fast and responsive due to the planing nature of its hull. The boat is usually raced with two people, but may be sailed single-handed in the lighter air.

The International Laser Class Association maintains very strict one-design rules, which enable the older well-maintained boats to remain competitive with newer boats.  ISC has several Lasers that qualified members are free to use for fun and racing.

Interlake Fleet 28 is made up of a diverse group of people who love to sail a boat that is a great racing boat and a family day-sailor.  Although the Interlake was designed in the early 1930’s, she is still a beautiful, comfortable and competitive boat for today’s sailors and their families.  She is easily handled by two people but appreciates a third for racing when the wind pipes up.
