The “Bomper” was built between 1951–1954 by Dr. J.R. Langstaff who also designed the deck and the graceful curved stern. 

The hull design echoes the Sheppard line of the day without the high bow.  Greater stability and a smoother ride in rough water are accomplished by carrying the “V” bottom to the stern (instead of becoming flat) and by non-trip chins (stripes on each side of the bottom) on the outside edges placed at an increasing upward angle.

The keel, frame and stem are made of white oak and mahogany strengthened lengthwise by Sitka stringers.  The bottom is mahogany marine plywood planked with Philippine mahogany.  The decks and smooth skinned sides are Honduras mahogany with battens inside over the joints. 

The 900-lb. power unit includes a Chrysler Crown, six cylinders, 115 horsepower engine which sits on a hardwood timber bed, a reverse transmission and “V” drive design.

Launched in July 1954 at Foot’s Bay, Lake Joseph and christened the “Judy Ann”, it has been renamed, in Dr. Langstaff’s memory, with his family nickname “Bomper”.  The “Bomper” served for many years as transportation from Hamer Bay to the family water-access-only cottage on Lake Joseph, Muskoka were it is currently docked.
