Planking & Finishing

Tom Adams Boatbuilder



Upon inspecting Miss Canada IV’s newly-planked bottom, a visitor remarked “Look at all those angles!  I didn’t know wood could go in so many directions at once...”

He’s right.  Douglas van Patten’s “keel knuckle” two-step displacement hydroplane bottom was radical and revolutionary. At speed, the hydrodynamic lift and vacuum-release venting of Miss Canada IV’s curled steps induced the hull to lift almost completely out of the water. Harold Wilson said she was “more bullet than boat” at 200 mph, balanced as she was on three points: the apexes of the 1st and 2nd steps, and the hub of the propeller & shaft.

When we received the boat, we discovered she had twisted and distorted from decades of being stored on an angle. We needed to true the bottom framing before planking, as the two longitudinal “halves” of the bottom have to be mirror images of each other if the boat is to ride correctly; having more “lift” on one side of the boat than the other is completely unacceptable.

The paint design of the bottom is remarkable; when Miss Canada IV is at speed, the impression that paint job gives is of a shark in attack mode.
