Gree, normally I'd agree with you about the structure and weight, but because of where the mast is (and associated loads)I don't think much as added to accommodate the centerboard. I saw the results of an ansys FEA of the beam/pod arrangement and the largest loads are at the mast step and that area hardly deflects at all, the board loads are minor compared to them. The center location has more to do with the banana boards than anything else and they might be removed soon anyways, they were added as a sort of insurance policy that I don't think is necessary after watching a bunch of LR2 videos. As that boat goes up and down hill and you watch the horizon, the top of the mast is always going forward, the boat just never pitches, even down hill in 12-15 knots and with 8 knot gusts and the crew sitting against the main beam, the bow never goes in more than 40-50mm. Not sure how they do it, but its like watching a train on rails.

Rolf, think I addressed the banana boards above, the 2 snuffers are for the 2 reachers, last I heard the wind can change strength during a race. The centerpod only goes back to the wingmast step, aft of that is a plug in compression tube and forward the prod plugs in also, whats not shown is a small inverted "v" striker under the mast step that is tied to the prod under the forestay and to the bottom of the rear beam. Weights and sail areas are in my first post above, think that the top of the mast is about 10.4m off the water and as I was told, total hull volume is irrelevant to most everything. As for expensive, it already is expensive and I haven't started to build it yet.
