ok thanks for the responce.

Syntex is like kevlar but it will not suck up ambeint moisture and it will wet
down like E-glass. at $39.00 US per. yard I am looking to buy the min. for one
layer per. boat. At this time I don't have both plans. If any one can help me with the max leinght of cloth for the beams of these boats please let me know.
what I am really nead to know is how to figure the min. yardage for one layer
on the hulls ov these boats. sorry I can"t figure the dam geomitry for this.
