This boat is good at what is was designed for; fixed seat doubles club racing.
It should work with sliding seats, and the clearances look like it should work for two drop in sliding seat units, however this has never been tried.
This boat will not work well for general utility, or for singles rowing, or for motoring, or for taking out a crowd (people have asked.) Other designs should be considered, there are many out there better suited for those applications.
This boat was originally intended as a one off so no effort was made to minimize plywood wastage when the plans were made. The panels for this boat are not presented in a nested fashion as are all the other boats on this site. Expect to use about 6 sheets of plywood.
