For the second test, we put on a working eight-horse motor and maneuvered across the bay beginning at 1,100 lbs and eventually getting up over 1,500 lbs.
We made quick starts and stops, zig-zagged and made sharp turns. At the end of the test, after the boat wouldn’t sink, we put the weight back down to 1,100 lbs and three men pushed on the side to swamp and sink it. It’s the only way the boat would go down.
