Thanks for the comments Ian.
Xtian, would you believe we discussed the fact that the bow thruters were larger when the build started but I clearly got carried away and made them all the same size, thanks for picking up on that, it's now been fixed, only wish i'd read your post before glassing them in, oh well nothing an angle grinder won't fix.
I now tell people that my quality controll team is based in france, you should see the looks I get!
please dont ever hesitate to point out mistakes like that, thanks
