CE, CLP, SA

Currently having 33sqm of upwind SA. Mast is 12m long, needs to fit inside a container, it is also possible that it will be a collapsable 2 piece mast, however wouldn't want it longer. CE is aft of CLP by aproximately 6-7% of WL. Theoretically it should currently have a slight weather helm. I want a trackless mast, mainsail luff will be on a wire and will have a fairing sock around the mast, that is why the boom is not attached on the mast, don't want it to interfere with the wire. I think the main will be easier to reef if the luff is on a wire, less stuff to break or jam, less efficiency though, but hopefully the sock setup will work and draft from the mast will be reduced. I'm not looking for a maximum efficiency rig, just a simple one with less stuff to break or jam, easy to sail single handed, less hardware, cheaper. There will be some flying sails for downwind work.

Also modified mainbeam, simpler, still sufficient clearance under the beam, checked local suppliers and largest round Alu extrusion available is 100x4, so beams will have to be made from wood/carbon, probably won't need bow foil, will add gennaker setup soon.
