1st carbon Karo on finishing streak

here are some bad pictures of the boats current stage.
The white paint is spray filar, in use to eliminate porosion pinholes, the deck is 2x80g/m2 glass, as it is the lightest laminate i had laying around.
this is the deck setup, a simple servo casette acting as a hatch and two pivot holes for the unarig.
the aft one is used in the lower windrange and the front one in the upper w.r. of the riggs, the exeption is the 1600something cm2 A+ rigg, wich is suitable only for use in the front hole.
The plan is to try a classic rigg on this boat, as the ce could be lowered by some 10cm! but sacrificing the relatively high aspect ratio.
here is everything but the bulb and the rigg, painting is expected to add some 5g.
The max lwl volume of the boat is 540g,
i am targeting for the 520 mark, A rigg = 40g leaves for the bulb 322g...
the above gives a ballast to weight ratio of 0.62 or 62% wich is ok, but the depron boat had a 350g bulb and 520g all up, wich gave it a ratio of 0.67.
before the gold cup i plan on building two more boats and i will try to make up the lost 8%(28g) of ballast.
To finish, even if i never build a lighter boat than this one, the composite hull is still the way to go, because it doesn't bend or fall apart and as far as i am concerned i prefer to sail a boat that functions and handles properly, than a faster boat wich is hard to control and demands alot of imput to get it on the water.
