      Keep in mind that the displacement would go up more than 100%! (Cube of
      1.3 is about 2.2)
      Structural calculations probably not simple, tho I suppose you could
      guesstimate. Panel expansions won't fit on plywood either, so you'll
      probably use a lot more wood and maybe have more scarphs to do. Are you
      sure you don't like the larger plans that are already available?
      Windsprint, Featherwind (is that the name?) , and the Japanese Beach
      cruiser come to mind, though I'm sure there are others. Bateau.com and
      Michalak have some pramlike boats in a larger size range, too. But of
      course, you'd probably be the only one around with an oversized Nymph.
      I've seen an article somewhere by Bolger where he considers (and
      rejects) a little cruiser based on a scale up of the Nymph.
