International Moth

Olav: International Moth

Rendering of my current Moth design which will be built this winter with assistance of a fellow student. Note the 2nd centrecase (aft) where a hydrofoiled centreboard can be fitted. Building method is foam/carbon sandwich, estimated all-up weight (incl. rig, all fittings etc.) is slightly above 30kgs. For those who are interested in the software used: The hull has been designed with Hullform 6 whereas the rendering has been produced using SolidWorks and the use of the VRML-output feature of Hullform 9.

      Looks good Olav. You might consider leaving out the 2nd centreboard case and save some weight unless you are convinced of the best location for it - see the current thread in the forum about foiler design (as im sure you already have). Then you can get rid of the conventional case when you switch to foils - or are you planning to use different foils and positions depending on conditions? Keep us up to date as you build, though!!!

      Hi Andy,

      Thanks for your comment!
      I think your're perfectly right regarding the two centrecases. Yesterday I read the thread you mentioned, found a lot of interesting things posted there and came to a similar conclusion.
      The boat is to have the Miller system (acknowledgements to both Rich Miller and Ian Ward by the way!) and I was a bit concerned about the required distance between the front foil and the centreboard (i.e. not too short for longtitudinal stability)so I guessed its value from the pics of Rich Miller's surfboard.
      However, leaving out the 2nd case will save me likely trouble with the LCE... :)

      Regards, Olav
