MORE BOAT PHOTOS

Manson High School Ag/shop program held their semi-annual cardboard boat races recently at Manson Bay Park. Every few years’ students in Kevin Amsden shop class spend about two weeks creating a boat entirely out of cardboard and duct tape. Before they begin to construct their boat, they must first learn the science, physics and buoyance in creating their card board boats.

A few of the key principals they learn are: center of buoyance, center of gravity, displacement, draft, hydrodynamics, keel, and design process. They begin by make small prototypes of their boat and floating them in a small pool as they add golf balls to simulate weight. They also learn the positive and negative design features of each boat. They then go full scale, which culminates in races at Manson Bay.

A big thank you goes out to lifeguard, Vickie Downey, who is always on hand for the races, Chelan County EMS and the Manson Parks Department, who allow us to use the park for our races.
