I think you could argue that mast rotation is adjusted by a control line, which is operated by the crew. Similar comments apply to the other examples given: the angle of the J foils is adjusted by a control line, which is operated by the crew. It's not so clear with wands because they work...

It's hard to talk up the class. They have looked to be very badly organised in recent years with attempts by people to fly their boats. The class sat back and did nothing, which showed a terrible lack of leadership. Either they didn't want the boats to fly, in which case they should have beefed...

This no vote may not be the end of the matter. Reports have the foiling supporters in the majority, but not up to 2/3. The results at the worlds may change some people's attitudes. Let's see what happens in the rest of the regatta.

Having the Rule 8.1 proposal defeated leaves the A class in no man's land. Foilers have won the first 4 heats of the world championships, so they are definitely quick enough to win regattas. But if there was a light air series then the foilers would be uncompetitive. The foilers are unstable and...

Wands for cats are going to be tricky. Ideally, the windward and leeward wands would operate differently. The leeward wand would be similar to the monohull version, but the windward wand should have the flap in neutral or even pulling down. You'd need 2 different wand settings and you'd have to...

I didn't say that wands were good or bad. Just that they don't comply with RRS 52. The moths have their class rules allowing anything except stored power, which is fine. But the catamaran classes have no such rules and we don't see any wands on A or C class cats. We saw a good example of this...

The proposals don't generally conflict with each other. If a rule is removed then the decision about the trial period proposal doesn't matter. But there is a possibility that the 1.5m restriction could be reduced in one proposal and also removed temporarily for a trial period in another...

Step (1) has been announced. There are quite a few proposals for changing rule 8 - all with the required support from 3 national associations - to be considered at the Feb 2014 meeting. They are: removal of rule 8.2; removal of rule 8.2 for a trial period; reduction of the 1.5m width...

In my understanding it's a multi stage process. (1) The proposal needs the support of 3 national associations 3 months prior to the World Championships in Feb 2014. If this occurs it will be considered at the AGM following the WC. (2) It needs a 2/3 majority vote at the AGM. (3) It needs a 2/3...

The Formula 14 has a very clean box rule: http://www.formula14.yachting.org.au/ You can have any sort of foil you like. They can even extend past the beam of the hulls. There's a spinnaker/screecher for downwind. They mostly seem to have been singlehanders, but even that is not required by the...

I suspect that wands are illegal because of RRS 52, which has been tightened up in the 2013-2016 rules. The moths have an exemption to RRS 52 in their class rules, but the A class has no such exemption. 52 MANUAL POWER A boats standing rigging, running rigging, spars and movable hull...

Every young sailor in the world wants to sail a foiling catamaran right now. They watch tv and see Jimmy, Ben and Tommy sharing jokes with their billionaire sponsor at press conferences: "We're going to fly down to my island in Hawaii for a party." "Oh - I thought you were going to give us the...

Yes - good point. My understanding is that the rules can be changed in a vote following the world titles in Feb, 2014. Otherwise, the next opportunity would be the world titles in Sept, 2015. Proposals need to be submitted 3 months prior to the AGM, which would be Nov 2013, so the deadline is...

Open 60s and Maxis cost millions. Moths are cheaper, more convenient and faster than an A in most conditions. They also used to crash a lot, but they have improved their systems recently. Moths have had a big impact on other high performance boats. I used to sail 18 footers and when the moths...

The daggerboard would initially lift because it's under load. The AC72s used the new windward daggerboard to roll tack the boat. Upon releasing the windward daggerboard it would be lifted by the hydrodynamic forces. So the control line would only finish lifting the daggerboard to its fully...

I can't believe that they're worrying about 8.2 and ignoring 8.1. DNA has moved their centreboard cases outboard to gain more lift. Why worry about whether people have to build complicated centreboard cases, but ignore the fact that they need to move the whole case! 8.2 at least makes some...

How does that work?

Are the hulls the same? It might be a good idea to try some of these new foil concepts on other hulls and to try existing foils on the Paradox hulls - if you haven't done this already.

I don't think this is what's happening here. The foiling DNA with J boards and the current world champion on board is a good indication of what's possible with the current rules. Mischa can win races in the right conditions, but is off the pace in light air. What's happening is a good example...
