CJW. The foil racing interests many. How big are the fleets you are racing in ? Are they one design ? Are you racing out of a yacht club or sailing club? How frequently do you race ? How long are the races ? What wind strengths are you racing in ? What are the weights of the 3 top places ? What are the gaps between sailors? Thanks.
There have been two national titles so far and we're in the 3rd year of a NSW state series which is run along side the Formula class, most are slowly converting to foil however

Generally we get around 20 or so entrants at the state series over Formula and foil. In the first two seasons it was heavily swayed towards Formula with only 6 or so foils at each round, but as the class has stabilised somewhat this season it has swung the other way; I think we had 13 foils at the first round this season from memory?
Because the class is so new and development has been so fast things were a bit all over the place for the first 2 seasons. People were working out what worked and what they could use, old formula boards, formula sails, what foils etc. In the last 6 months or so though the development has really stabilised and personally I think the gains going forward now will be much smaller. All of the gear over a wide range of manufactures is very very close in performance, you just have to look at the PWA to see that....PWA is currently driving all of the development really. If you buy any race foil from any of the big players, any race rig and any foil board, or use a formula board (which we allow in Aus) you will have a competitive setup.
Courses are windward/leeward, usually about 1 nautical mile top to bottom, two laps. First foil usually finises in 16-18 minutes. We aim for short, sharp races. Because the the speeds are so high the gaps can look massive.....however actual time wise are they much bigger than say in a raceboard fleet I don't know? It's a highly technical class though and the speed differential between someone who has a high skill level and their gear tuned up to perfection and someone who doesn't can be big. I don't think the differential would typically be so big in say raceboards....but i'm guessing a bit there.
In the NSW series I would say it has to be a minimum of 10kts before we race as we have to cover the skill level of the entire fleet. Some could probably race in 6 kts but the other problem with 6kts is you get lulls of 4 kts and that is difficult....you can foil through it for a bit but you have zero height and won't get going again. Personally by 10 kts i'm fully powered and motoring. We race up to 30kts+...if people are still getting around the course, it's on. The first Nationals the average wind strength was probably 25kts.
I'm 65-70kg, use a starboard race foil this season (used an F4 I highly modified last season, thread on here somewhere), Severne HG2 8.0 and 9.0 and a modified JP135 to PWA specs, IE 91mm wide and parallel rails. The great thing about foiling is the range of competitive weights seems to be big. I reckon anywhere from 65-90kg is competitive as in our series (basically PWA rules) you can just tune your gear accordingly. This is the one issue I see with the ifoil, being a one design, one sail setup; there will be an optimum weight range. Personally I think they should have had say an 7,8,9,10 sail sizes and you can register 2 for season, something like that. Keeps the costs somewhat down but still allows gear selection for your size. It makes a big difference. At my weight i'm often 1m, sometimes 2m less in sail size than the big guys but the speeds are literally identical, that is not possible in normal displacement/planing sailing as the more power you can hold, typically, the faster you go. Because of the drag profile of a foil you can have all the power you want....you're not going much faster, but up to that point things are very even. Trade a bit of power in the rig, for a bit less drag in the rig....it all even out very nicely....it's quite amazing.
I come from waves and freestyle (still do both) but i'd never raced windsurfers before; I used to race dinghy's and Catamarans at a National level when I was younger. Raceboards don't interest me and I'd tried Formula once but unless you were 6ft+ and 90kg you had no hope, it's different on the foil, us light weights can be competitive, and the heavier guys alike and that's a big thing. It's a fantastic style of racing and I think the Olympics will be better for it. It's also way easier on the body than formula and raceboards, once you're over the 'scared of it' factor which seems to put some people off. I won't sugar coat it though the learning curve to get to the front of the fleet is high but that's the same with anything and this is windsurfing, everyone is willing to help.
TLDR; racing foils is bawse, try it.
