Read the article in the tuning guide section about rudder pin. It seems to be the opposite of what's on the Waszp site in the initial tuning guide there.
So upwind, the pin should be all the way back? In doing this is there a different set up for the main foil since this changes the angle of attack a lot? Or the ride height adjustment takes care keeping the main foil in the water?
I've sailed the boat for two years with the pin all the way forward upwind and a few turns back off the wind. I've set the boat up to the Waszp tuning guide.... So I've just been trying to sail the boat level fore and aft once on the foils. Pin all the way forward to get on the foil... It makes sense that pin back would get the boat on the foils sooner....
So great to see this site starting to develop!
I noticed everyone was bow-up in the Perth games and was surprised. I'll have to try going to windward without pressing the bow down so hard, I can't point for sh*t right now so maybe that will help.
Thanks! Depends which side you count and what counts as a thread! I'll wind it in one turn and go from there.
That looks like 18 threads to me, but I should say with the new foil we are still experimenting with rudder position. The overall theory is that you want the full range of the rudder pin, so you can get the bow up upwind and down downwind. Hopefully we'll ave better info for you soon
Thanks for the question. Keep in mind that the original tuning guide was modeled after the moth and it was written with much fewer data points than we have now. Conner's article also works off of the assumption that you have 16 turns out on the gantry, which is much further out than the tuning guide recommends. There may be merits to putting the bow down at times; however, even with the bow up, the ride height will balance out any adverse effects. In practicing this, we found that the bow up (going upwind) allows the boat to point a lot higher. The speed differences with putting the bow down do not appear to pay off with regards to VMG. Another great thing to watch is the video and pics from the waszp games in Perth - you will notice everyone sails upwind with the bow slightly up.
