I wouldn't say it is pointless, but there are realities to having disparate boat types in the same race. Take something like the Bloody Mary in the UK. It is a one day pursuit race on a reservoir in the middle of winter. The weather sucks, but they get several HUNDRED boats out there racing portsmouth. The boats range from Toppers and Wayfarers to International Canoes and yes, foiling Moths.

When it is breezy (2013) the Moths clean up. When it is light (2015) the Moths get smoked by "slow" boats. As long as everyone excepts the realities, then I don't think it is a big deal.

On a long windy reach, a foiling cat is going to kill all the beer at the finish before the rest of the fleet is done launching.... but on a light upwind or deep run the last thing I want to do is drag around an L shaped board.

I love to foil- it is a completely unique feeling and is highly addictive. I also love big fleet F18 racing. It's all good.
