The carbon was made into rods in the corners of the triangular beams. Also carbon running down the outside of "shaft" of rudder. Just uni tow, no cloth areas used.
Very economical, tow was very cheap.
You can use it here and there to beef up connection points. And make small parts with.
Wrapped around things it works like straps.
You become handy at using fibres and resin and bog to make things with. Use less other materials like screws, nails wood etc.
Made the chain plates and rudder bearings with glass for previous trimaran. Save on expensive yachting hardware.

This is a good point. Dougs wet layup carbon might not be
any stronger than s glass wet layup, but it is stiffer.

|They are the places where rigidity is important.
Essentially a thick skin on a hollow or low strength
core.
