Picked up my newly finished main foil from the builders. Need to wait a couple more days before giving it some 2000 grit and a polish. I am going to send up my rudder and my verticals as my rudder makes the most fucking annoying whining noise when going at speed.
So, put my rig further forward, this felt much more balanced. Sorted my bridle out properly. Went front hole on main foil. First thing to note, do not stab yourself in the face with tiller extension when getting into the boat. Next thing, make sure you have taken off the masking tape that has gone hard due to epoxy spray on main foil.Then after 15 minutes swimming taking masking tape off, send it as hard as you possibly can.
It was 18 to 19 knots out the north on friday with a good / dangerous chop. Glenny and I did 5 hours of epic crashing, pitchpoling, and some seriously fast sailing. Boat felt much better with the changes I had made. I did not put wand limiter on this friday. Spent an hour in the flatter stuff behind the island doing manouvers, think we chucked in 100 plus tacks. Finding that the mach two gives you much less room for error on the way into a tack but gives a lot more room for error on the way out.
Downwind I had some HUGE wipeouts, go hard or go home seems to be the way the brain is processing the mach two right now.
Saturday I extended the main push rod in the main foil and wound off 10 turns of lift on the main foil. I also put a wand limiter on to stop the wand going forward all the way. This has helped with the ridiculous ride height that we were running and now have only a couple of inches of rudder in the water in the flat water. This is impossible to achieve in the waves so need to get a ride height thingy or find a happy place in between.

I would highly recommend getting the height adjuster as it sounds like you need it. Being able to control the height means you dont have to compromise and can send it with confidence downwind whilst maintaining height upwind.
It will not only deal with the upwind/downwind height differential but also with the port/starboard one. We now have 6 active Mach2s at Hayling Island Sailing Club and the one thing we have learnt is high is fast.
Details of how I set it up are on the Sept/Oct 09 posts on my blog – haylingmothie.blogspot.com.
