    I have all four hull parts now, I test fitted and put a flange on the bulkheads. I also glued together pieces of particle boards for the front beam plug. Sam also heat formed his core in an oven and fitted it in the mould today. Check out the progress. http://www.ah-sailing.blogspot.com/

    Cool build. That thing is going to be really light and fast when it's done.

    Thanks the class weight is 165 lbs, so we are aiming for 159 or 160 so the boat will not go overweight in case it absorbs a little bit of water.

    Jeremyh, can you tell me what your rear beam diameter and wall thickness will be. I'm building a tri and my cross tubes will need to be between an A Class rear carbon beam and an F16 rear carbon beam in diameter and wall thickness based on righting moment.
    And if you happen to know the same info for an F16 rear carbon beam that would be great.
    Good luck with your boat....

    The rear beam will be 3.5 inches in diameter and at this point we think a safe assessment is between 2 and 3 mm, we are still working out a laminate schedule for the beams though. I'm not sure of the wall thickness on f16 beams but they can be either carbon or aluminum. Most are aluminum but I've seen a Bimare with carbon beams that are 110 mm in diameter.
