    I know that most proas have very narrow vaka's with relatively high freeboard. But racing sit on top OC's have low freeboard, although still a very narrow beam, perhaps to help in paddling.

    In a sailing outrigger canoe, is narrow beam and high freeboard necessary for the vaka?

    Wouldn't a wider, flat bottomed vaka with low freeboard be able to plane and thus go somewhat faster for less weight and wetted surface (ie square underwater profile has less wetted area per given displacement than a rectangular one)?

    It depends on if the thing is long enough to take advantage of a high L/B ratio at its weight. If it can't be, at the very least 10/1, or preferably even skinnier-say 14/1 or above- some consideration could be given to a planing hull. Effective planing hulls can be pretty short with weight limited by how much SA you want to pile on and how much RM you're willing to generate. Two person 12' skiffs are among the most highly powered monohull sailboats...
