When a Wasa owner had a wish for a boat with two separate sleeping rooms with a corresponding shower and toilet, the designer, Leif Ängermark, sat at the drawing table and became Wasa 420.
The increase by a few centimeters in length and height created a boat with more volume and a comfortable accommodation in two separate cabins as well as a large common space for navigation, cooking and socializing.
As usual, Leif has maintained his basic concept with a lighter displacement and a well-balanced length/width ratio. Leif prefers the more slender boats, all in order to keep what is the most important characteristics of Wasa boats; beautiful, well sailing, fast and lively. About 25 boats were built.
