I think the F18 class is trying hard to keep the cost down, but it's a battle hard to win. Each development is incrementally more expensive.

The board length is a great example, a set of custom autoclaved carbon boards for a F18 do cost a small fortune. Some top teams have them made by Reverie. £1100 for one. £2200 a pair. That's $3500 just for the daggerboards...

I hope that the class rules are going to be amended to limit the length of the daggerboards to limit cost.
