David Hollom was a GB designer for 12 metres back in the 80s and 90s working with British and Swedish AC syndicates. His background is in model boats, and he has tried a lot of things....
In 1983 he was key to Australia II being able to defend its winged keel protest, as the UK team had already got his winged keel design cleared by the measurers. The British, however, did not have the balls to build the boat!
He designed a very odd looking 12m for Fremantle 88 which was not used but performed very well at the 12m worlds which followed the AC. It was then lost from a container ship returning from those Worlds. The 12m was no longer the AC class and the UK gave up for a few years. He was marginalised by nationality rules but had consultancy work for the Swedes.
Latterly David has designed some fast International 14s and National 12s in the UK.
A rather interesting man, and particularly unconventional. Arguably what you need in a competition like the AC.
