    Nice....that looks pretty good.
    i just started a new design, so i am going to be on my other computer a lot.

    Hi there what design software are you using cheers

      I use Vectorworks. Been using it since 1995. It is not widely used in the US except in the exhibit design world, where I worked for 7 years. It is extremely easy and fast. I also used Solidworks to create the 3D model because it has a better bevel control. The bottom paneling is beveled 20 degrees. But once I create the basic boat shape, I open it into Vectorworks and add all the other parts, mast, sail, rudder, rudder box, dagger board, dagger case, skimmers... You can do assemblies in Solidworks but it is slower than assemblies in Vectorworks.

      @markpalmquist ok cool thanks for that mate it's a little beauty of a design you got their mate..

      @@Juan-jm7sf also, with Vectorworks, you can take screen shots of other boat designs and import graphic images into your document and scale them and trace them. That is how I discovered that the center of effort on modern trimarans is 12% behind the middle of the main hull. As far as I know you can’t easily do this in other 3D modeling programs.

    your 1/4 beam buttock angle should be 2 degrees or less.
    i would go with a 1-1/2 degree 1/4 beam buttock angle, and give the transom 5 degrees forward.
    spending a little more time on a design can make a big difference.

      Thanks for your comments. Are you talking about the angles at the back corners of the top profile? Or from the side view?

      @@markpalmquist dived the beam measure into 4 , then draw a vertical plane, fore and aft, and intersect that plane with hull ...if the resultant line is not a line, then snap onto it and make a line that is the closest approximation.....in the side view, then, see what the angle of that aft most line is.....that is called the 1/4 Beam Buttock Angle; and it is very important to any hull's design.
