Can I omit crosseam 2 or 3 from the Tiki 31?
We do not think it is a good idea to leave beam 2 out, because of the spacing apart of the beams – it would leave too little support between the hulls in the front part of the boat. If any beam is left out it would have to be Beam 3, but even then we would recommend having a shorter beam here from inner gunnel to inner gunnel, to support the platforms, rather like on the Tiki 38 (you can see her layout in the Design Book) and also the second mast if you want to keep the original rig. The crossbeams of the Tiki 31 are quite a good size so I don’t think you need to add to their size (to make the beams stronger one should add to the thickness of the top and bottom flanges, you could add 10-15 mm extra in total thickness). However you may like to add an aft netting beam like on the Tiki 38. This beam, which is circular, is the same diameter as the mast and can also be made the same way, or else an aluminium tube can be used. This beam is lashed into semi circular sockets cut in the stern h
