Hi, I've refurbished a UK Class 5 landyacht K101. And recently sailed the yacht in the first bit of strong wind I've been able to get out in. 25mph. I had set up the axles and camber with the method I posted up on this site a couple of months ago. The first run in the morning was all good. The wind was on shore, so the course was a simple reach to the gybe turning mark and then the bottom mark was a tack. No problems.

Here's where it gets interesting. I re-tracked the yacht on a fellow club members specifically made tracking device on his road trailer. We also changed the camber. More upright than before. The yacht was also set up with just a little toe out, less than I had been running.

We raced the same course. The yacht was instantly more scitish, faster but was noticeably more difficult to get around the gybe mark. The up wind mark was a different matter. On turning into the up wind the front wheel lost traction instantly, with total loss of control. I tried various methods to improve the tacking of the yacht. Changing line into the corner, sitting up to shift my weight forward etc. But to no avail, I kept loosing front wheel traction and control. Ending up with the yacht fliping backwards.

I was keeping the sail sheeted in as much as I could, but I have to easy it slightly from just above my eye line to skim the top of my helmet.

Is this issue purely down to not sheeting in enough? The sail was luffing a bit going into the turn, due to possibly extra apparent wind due the extra speed relative to the mornings session. Or is something else going on?

We talked about it at the club and there was some suggestion that extra weight, in the form of some lead is sometimes applied over the front wheel and ballast is also out in the body of the yacht. Also suggested was a slightly longer mast to allow me to keep sheeted completely through the tack.

I'm 5'3' and 10 stone, so the foot controls are as far forward as I can get them and I guess my upper bodies mass is slightly further forward than most?

Any ideas, suggestions? One last thing the wind may have got up a little bit more in the afternoon, topping out at 29mph
