I think a lot of the discussion is mirroring what has previously happened in the moths, it's actually quite interesting how similar the topics and their arguments for and against are!!!

The very first foiling moth and its cousin were retrospectively banned. The builder then went on to develop the next generation foiler that you see today. Very sucessful transition don't you think.

A carbon moth mast costs less than an aluminium moth mast, I should know, I got the quotes! Admittedly one of the technologies to build carbon moth masts (filament winding) is now very mature, hence very cheap, so the other methods are forced to come down to a reasonable price.

Moths were using fixed T-foil rudders for years very successfully. There was a transition period of a few years, while the foilers were developing, where manually actuated rudder T-foils were popular and sometimes complicated. The system now is such that there is almost no actuating of the rudder T-foil while racing, and the systems that are used are again, very mature and not very complicated. Applying them to a twin rudder system is another matter though.

Carbon masts are already allowed in the rules, the weight restriction sort of dampens their main benefit though, that of reducing weight. But the other benefits are still there, increased stiffness, customisation to a crew weight, etc...I don't think deleting the weight restriction is going to help the class as a whole. Someone who wants a carbon mast can already buy or build a carbon mast and have most of the benefits associated with carbon masts. They are not necessarily expensive or hard to build, they just require a bit of thought.

If you propose a rudder T-foil rule amendment, make sure you get it right. I wouldn't want to see a complete banning of T-foils, nor a poorly thought out or worded compromise that allows some systems but has unexpected implications.

My current stance is:
- Leave the mast tip weight rule as is.
- Leave the T-foil development alone for a while longer to see what emerges.

If the T-foil debate becomes an issue, the class is allowed to vote on it in the future and any builder/buyer just needs to take that risk if they want to. The discussion here and on the rigging lawn should give builders a good indication of whether it is wanted or not.

I for one will be attaching fixed T-foils to the bottom of my rudders eventually (probably a year or two away yet), and probably pack the rudder pintles as desired for the conditions. There may be some sort of system to change the angle on the water but only between races, something like racing car spoiler adjustments in pit-stop.
