Likewise in the Elementarry sizes there are other ways to articulate cross beams, bringing the vaka across and over the deck of the WW hull with a double joint. That dispenses with the patent issue, and allows masts on separate tabernacles so that all you need do is stand them up and slide into bases while still on the trailer.

Still I cant help thinking a smaller boat might in the end be more fun, be easier to handle singlehanded launching / recovering / sailing, just with a fold out tramp outside the WW hull. On our 2:1 ratio thats a 16ft vaka. Plenty of scope for experiment with sail rig and perhaps a simple diagonal foil to WW
