How to measure your transom angle
Place a carpenter's square with the long side ( 22 1/2" ) against the keel. When the short side ( 14" ) comes in contact with the transom, take the measurement ( see the sketch below ) between the inside corner of the square and the boat bottom. Each 1/4" is equal to 1 degree in slope of the transom.
