I thought that too. Because the rudders rough the water up more than I like but they are strait as.
I don't need a remedy guys as the boat is for heavy weather and it operates great now. I am just saying..it seems to have worked backwards to what everybody says.. it is just an odball thing and I wondered if someone knew why.

wow..THAT is news. Can't wait to get out and try it.

So all I needed was balls of steel! I'll go and get some. 316 stainless?
Thanks for that. It is a really important bit of info as I am sure you understand.
Both are counter intuitive. stay tight and move forward.... you'er not taking the p*** are you? : )

Downhaul is an important meidum of contro on the boat as it has no rotation restricter as such. I quickly realised that the mast rotation could be set buy more mainsheet tension but then realised also that the downhaul affects the rotation as well.

Standing the mast up straight also increases the sail power. Depending on the wind o' the day, you may need to rake the mast back for better control.
Figure out your rudder problem with the mast raked 10 degrees and then you can tune the rudders to the rake.

Yes. it is a cool boat. I was really surprised by it as I only bought it for the beach wheels! I was going to sell it on but had to go for a ride first. It is strong and loves deep water and big swells and is in the water in about 12 minutes.
I have found it had a lot of eronious controls on it and have been very happy with simpler set up. It reacts very well to mostly inhaul and main and body weight.

I have sailed round hull and hard chine monos a lot in my youth and would suggest the rudder losing bite causes round up more than hull shape as the healing action is accellerated. I don't have a jib on this boat. I am very concious of keeping boat flat and rudders tightly set and very concious of the inhaul setting and trialling different settings for that.

Oh, is weather helm when the boat wants to turn INTO the wind...just kiding..

I think the boat wanting to bury is very connected to the mast rake forward. I was drag racing a H16 in 25 and it was happy and I was driving my boat with both noses underwater! Their mast has the crazy rake for that reason I am sure and I thought to rake back and put a hooter/jib on for downwind and light weather. So far it has worked well but I was just surprised by the opposite rule on my boat.

This is interesting. The rudders are exactly strait and even and I have believed that the lee rudder is just not quite happy when driving up wind! It is messy and noisey. I had been wondering if it was just the drag of water until the stern lifts out.
Can anyone else confirm I might need toe in?

Even toe is essential to tracking ability. Mast Rake and rudder rake need to mimmick each other to maintain balance of power.

Unless you have shared lift................

On rudder tow in....Bill Roberts told me that you want between 1/16" to 1/8" toe in...that is... the distance between the rudders center to center is 1/16 to 1/8" shorter on the leading edge than the trailing edge. At least that is what he recomended for my Supercat.

When I bought my boat the former owner he had them set up all wrong...so bad I couldn't even tack the boat...on every point of sail it felt like I was pulling a 5 gallon bucket behind the boat... that all went away with tunning in the rudder tow in.
