Our Sail Design, almost...

A Colin Archer,
a famous Norwegian rescue boat

Here's an example of the gaff rig sail design that CAI is going to use.  'Not very commonly seen any more.

Notice the gaff sails (with a spar or bar across the top.)  Good for sailing downwind.  Not so good for sailing upwind.  Of course cruising should be all down wind if you are lucky :-). 

That sail at the very top....  not sure we'll have one of those.
