Ok i put 15 lbs worth of rubber dumbells in the bow as far forward as they would go and spent the last 4 hours in 15 k winds and 1' chop.

The result is a new boat. I can now lean back ..tilt my head back and close my eyes and not feel twitchy. Initial stability is greatly improved, the boat tries to weathercock slowly when moving..it tends to stay neutral sitting still...it leecocks when i lower the skeg.

Very happy with that...all i need to do now is determine how far forward to move my seat to simulate 15 lbs at the bow.

thanks all.

: Thanks i will try that.
: To enter the data into cad i would first have to learn cad...
: I will do it if i have to.

: I do know that i need to move my weight forward and i can try a few trial and
: error seat adjustments and see if i need to move my coaming forward...i
: need 20k winds to test though...next stormy day i'll get out there and try
: stuff.

: I also recognize that adding 1/4 " to the petrel meant adding a lot more
: volume to the bow than the stern and the seat should have been moved
: forward then.

: Yeah i want it to weathercock with skeg up..and hopefully neutral with skeg
: down.

: On the balance board...should'nt i be in a sitting position like i would in a
: kayak?
