|    The next question is how to use high density XPS, Finnfoam or Dow, etc in "intelligent infusion".  

As stated in prior messages and confirmed by Rob, one could manually carve the surface to make epoxy channels, and holes through to the lower fabric, and save distribution fabric. Or use distribution fabric.

If one has any sort of urban area nearby, look out for a 'maker space', to see if they may have a 'shopbot'. Ours does, and it is my plan to use it to cnc carve the surface and put through holes in it.

I was thinking to start with a pattern like '3d core' uses. Machined hexagons. Through holes at corners.

P.S.

Howard, you should post about your catamaran here.
