Tweaks

As the class is a strict one-design class there aren’t a lot of changes that you can make, but there are a number of ‘racing tweaks’ that are worth doing. These focus on making the boat easier to sail to 100% of it’s potential and not anything that will have a speed impact as that’s outlawed under class rules!

These tweaks have been compiled into our Tweaking Tips guide. If your boat has already been raced on the events circuit it is likely that a lot of these tweaks, such as shortening the trapeze wires and sanding the rear edge of the foils, will already have been done. However there should still be some useful tips and information to be gleaned from the guide regarding knots and rigging and even the best places to attach food and snacks to keep your energy up in between races!

You should also take a look at the Sailing/Tuning page of this website which includes information on measuring and rigging and detailed rule interpretations on what you can and can’t change.
