This one has got me scratching my head as its the worst sailing innovation hmm.....
Ok, here are some initial suggestions:
1. AC lawyers - naah, that's just too easy
2. Twin wheeled small cruisers (see above). There's this whole attitude that big racers have twin wheels, and they go fast, hence if you have a smallish (i.e. under 40 foot) production cruising boat and give it twin wheels and bingo! its a flash racer. Nah, doesn't work like that.
3. Anything involving the word "frostbite". No, nope, ain't going to happen, seriously there's a clue in the name there. Its just a ruse for masochists to get some race points over the sane.
What else? Well I know there's something that annoys ol' Buff, but maybe that's best left to another day.
