RE: Formula or isonic 155 for max speed ?
The reason for my original question was that I was considering competing in the gps-speedsurfing.com formula rankings.
The regulations mean that the IS 155 would be classed as formula because its width exceeds 90cm.
So sailing on super flat water (at West Kirby) in as maxed out conditions as you can manage, in ideal for speed wind angle , I wondered if the IS155 would manage to go quicker ?
In the end ,because of lack of information, I have elected to go for a second hand F159 which seems a fairly safe choice - and I have to say it is a joy to sail with 11m sail.
Just how fast I will be able to pedal it - well that remains to be seen
