side tanks are in!

Hi all,
Finally its starting to look like a boat!Side tanks have been glued in and laminated into place. The port tank will act as a spinnaker chute, helping to keep a clean cockpit and the stb tank will be a bouancy tank.
(this is a view down the spinnaker chute from the bow)

All of the hard points have been laminated into place, which is 5mm thick fibreglass plate, with approx 4 layers of carbon over it on the floor. These will then be drilled and tapped for an M5 or M6 bolt to attach fittings.
After re-weighing the hull with the following; sides glued in, foredeck on, gantry in the boat. The hull came in at 39.5kg which isn't bad, but i doubt that we will make the 45kg lower limit for the class (hmm that 6kg's of lead would have been good!)
This is an image of me trying to work out how to mount our vang system. The blue pen lines are a radius out from the centre of the mast, while the other lines are different layouts of connecting the system. The lay-out above with the green string appeared to follow an arc from the centre of the mast the best, meaning that when we was our main out and out boom angle increased the distance between the mast and boom vang will remain the same, giving a constant boom vang tension. This whole set-up will be discussed in more detail once it has been built
