Equilibrium rig,how its done at the bottom of the earth.

Thank you Walt - I have just had a look at some Sunfish - I see what you mean. The mast is relatively close to the forard end of the boom so the impact on sail cross-section shape is minimised.
Thank you. Keith:cool:

What thickness of wire should I use for a metre long dhow using the “Brett Unarig” - any suggestions? Also, as the hull is wide, would a deep weighted keel be necessary does anyone think?
Any helpful suggestions most appreciated. Keith
