      Any of your WDJ or Birdwatcher builders care to reveal the thickness
      of the polycarbonate/lexan you used for your windows? 1/8"? 1/4"?

      Plans for CLC say nothing. Write up from Chebacco News mentions 1/8"
      laminated glass.

      Anyone?

        The plans call for 1/4" "plastic". Lexan is way more
        bulletproof than plexiglass. My local supplier offers
        a host of plexiglass options, however. Enough lexan
        might cost more than buying the boat second hand.
        Well, that might be an exageration.

        I think it would depend a lot on where you plan on
        sailing this thing. Bolger relies on this material to
        provide self righting ability. If you are depending
        on that to save your life in cold water, it is one
        thing, and if you are depending on it to stop your
        from taking an otherwise pleasurable swim, it is
        another. At 1500lbs displacement, this boat has water
        pressure of about 10#/sq. ft. on it. You could do a
        simmilar calculation for whatever you are planing,
        then test a sample.

        How to test is a difficult call. Let's say your
        largest window was one sq ft a piece over that size
        opening, not screwed down, with twice the weight in
        sandbags on it - 20#. I think that would hold, And I
        wouldn't worry. When installed with a fastener every
        few inches, it would be much stronger.

        If your largest hole was 2'x2', that much window, not
        screwed down, but with 80#. Well, I would have to see
        it.

        A more realistic test would be a sample window scred
        down, about 5 times the weight on it, but that would
        be a lot more trouble.

        The Gougeons book has some stuff on platic windows.

          Bolger's plans specify 1/4" "plastic" for Birdwatcher. It is not clear
          whether Lexan or Plexiglass is preferred. At any rate, 1/8" thick
          would be too thin for such broad expanses of window, and the 1/4"
          matches the plywood thickness used elsewhere on the hull,

            Research would seam to indicate that polycarbonate aka Lexan is 2-6
            times as strong as plywood.

            So, if I use 1/4" thickness polycarbonate with the 1/2" ply
            pilothouse on the CLC, I should have a nice strong structure without
            having to go to extraordinary lengths to to strengthen the ply
            structure to hold non loadbearing windows.

            One question answered.

            Now, can I buy clear polycarbonate and use the auto window tinting
            film on it before assembly, to get exactly the shade of tint I want
            on the windows?

            I'm pretty sure it's a water based glue they use.

              I got some film for my shop windows that block about 75% of the heat, but
              only about 10% of the light. Great stuff - it is made for buildings rather
              than autos. It does not use an adhesive, it just sticks by imagination to
              the inner surface. The same stuff comes with a tint if you want it. Try
