Re: M_Boats: UHMW, HDPE, Cast Bronze

[Wcpritchett]

I think the HDPE would need reinforcing to be strong enough. For weight you could cut a rectangle section out of the board near the lower trailing edge and fill with lead.   It could be captured on all 4 edges with pins and would be flush with the board.  Lead is 750lbs cu ft so it doesn't take much.  Probably a few pounds would do on a small board.  Just for reference I had 40lbs of lead holding down a 32' sharpie centerboard...the board was made of 2"x10" wood planks drift bolted together and approx 10' long x 3' wide.
