Guillemot Double: This design is an
adaptation of my successful Guillemot designs to a double. I have just finished
making one of these for myself. It is a roomy, stable and comfortable boat. I
drew the stern to accept a rudder but it is not required. I will have a photo of
the boat up soon. The cockpits are quite far apart, permitting the paddlers to
be out of sync. There is room for a hatch between the cockpits. This is a good
two person kayak for beginner to intermediate paddlers. More experienced
paddlers who want a tandem should look at the
Fast Double.
