“A 17 1/2 foot Cherry and Mahogany Gentlemens racer. Built by Doug and Verna Harrison of Coburg Ontario. She is powered by a 300 hp afford 351 Windsor V8. Thumper was built over a 3 1/2 year. Between other projects to satisfy my desire for a nice looking and sounding classic run about. The deck was modified from the original Glenn L plan to suit my own concept , it was made from Cherry lumber. Cherry steering wheel , windshield and brackets – we’re all custom designed and made by me as well as the instrument panel. Finish is English chestnut stain and royal blue marine trim. Doug Harrison Thumper is the 11th boat built by Doug. He started with sea fleas when he was a youngster then runabouts , cedar strip canoes,  an all wood tugboat and a Ted Brewer  designed 34 foot steel offshore sailboat considered by Editor of Cruising World to be one of the finest steel sailboats he has ever seen. Doug is an industrial  electrician , class A and C mechanic, shipwright and master cabinet maker that made boat building and enjoyable hobby. All this was done with his wife helping and supporting him for over 23 years. Thumper is now owned by Bruce in Yvonne Mackay, who  are so proud to have thumper in their family. Thumper won first place contemporary in the 38th Annual Vintage Boat Show July 7, 2018 in Muskoka.
