It always seems that the argument for having such restrictive rules are to keep costs down and slow down development. But almost in the same posts it is always claimed that the best Tigers at big events are stock boats ! Suggesting that "old" gear stays competitive in the F18 class as well !
So what is it guys ? Either the lead tiger have the lastest go-fast stuff that simply isn;t TIGER OD or they don't and the whole foundation under the restrictive rules falls away.
I saw Mitch Booth and his son build a stock Tiger right out of the box at the Tiger Worlds - and they did very well on it. If I remember correctly what my friend who went to the 2005 F18 worlds told me, Darren Bundock's Tiger had the stock Hobie Tiger spin - not the new flatter F18 spin. I think he also had the stock "one-line" spinnaker tack/halyard system - instead of some of the latest greatest separate internal tack line with spin halyard cleat on the mast.
My point is I think what makes the top boys win is not the boat - its their sailing ability. That is why they do good on stock boats. My conclusion is a lot of the latest tweaks make a marginal difference in speed. Occasionally something like the new style "Super square top" mains comes along that really seems to have an edge.
One advantage the top guys have is they are often working with brand new sails and brand new hulls, boards, rudders. Assuming the sails are cut consistently then I think there is a real advantage in a crispy new spin for every regatta.
Locking in on a class sail design may give a more level playing field - and I think a side benefit is that folk would spend more time focusing on their sailing (with higher performance returns) than worrying about some perceived edge from the latest hot main or spinnaker.
