Bruce Kirby; On Designing his Mk 2

Bruce Kirby continues the story on the history of his 14 designs:

Developing the Kirby 2 (Flame)
"After the Canadians had won the 1961 Team Races (I had competed with the Mk 1. The Team Races were held in Toronto), Ward McKimm had said that if I would do a Mk 2, he would take the first one. Then I got Harry Jemmett of Kingston, my brother David Kirby, cousin-in-law Fred Anfossie from Ottawa and 2-3 others, including myself to sign up for the first batch. The boats were built in fiberglass by Johan Tanzer, located west of Montreal (there was no wood prototype). The first Mk 2's were launched in 1962. Johan Tanzer went on to be successful manufacturer of small cruising boats. The Mk 2 was also built in fiberglass in the U.S by Roger Moorman of Gloucester, Virginia (designer and builder of the Mobjack). Later on, the Mk 2 was also built in wood by Souter. Graeme Hayward had the first of these and it was in a Souter Mk 2 that Stewart Morris won his last of 10 wins in the POW."
Differences between the Mk 2 vs. the Mk 1
"The Mk 2 was not as deep under the mast (rocker), not quite as fine forward at the waterline. and not quite as full above the waterline forward. The Mk 2 was also slightly narrower on the waterline amidships. She would get on a plane earlier than the Mk 1. These were all very slight differences, but they added up to make a better all-round 14. The Mk 2 was very easy to sail to it's top potential."
How did American Roger Moorman come to build the Kirby 2?
"Roger Moorman had a glass layup system that he developed for the Mobjack that used a core material. The system looked good - I can't remember how we got in touch; Roger came to Montreal and taught Hans Tanzer his system and they both built the Mk 2 14's that way. The 14's got 1-2 in the 1962 CDA at Pointe Claire (I was first, Harry Jemmett was second) and that fall, Graeme Hayward asked me to have Souter also build them in wood. Graeme had the first wood Souter Mk 2 and quite a few were built by them. I think 'Pudders' (Jeremy Pudney) had one of them as well."
