    I suggest you add Bolger's book on rigs to your library. He's a canny analyst of a wide variety of current and historical rigs -- http://www.powells.com/book/-9780966699500

    There's the general opinion of what constitutes a Crab Claw rig and how it apparently works differently to other types of three cornered sails, then there is the actual thing and it's function in the real world.

    Without doubt a claw rig has at least 2 spars supporting a triangular sail on two edges(the long edges), with the apex set downwards. and beside this basic form, it has but one adjustable controlling line (the sheet).

    This very simple configuration is versatile and remarkably efficient, without having to venture into the realms of vortical flow theory.
