No prob Ronald, there will be 400mm sleeves inside the ends and also a sleeve inside the middle of the main beam. Actually a total overkill. These beams are actually 0.5ft narrower than the Nacra 18SQ that used 100x2mm without any reinforcements at all crazy. There will also be a stainless 40x3mm dolphin striker.
