Its about 42 inches Chris. Twin screw, I have had it on the bench, tools ready, twice now, then just couldn't bring myself to tear it apart, I really want to do it, but I think its going to be lot of work, and I don't sail much now really, and will it go any faster, probably not.
I tidied it up earlier this year with a view to sell, but again, thats twice now, and then it ends up back in the box for another 6 months!
