If your own weight is less than 200 pounds, my recommendation is to go with the Guillimot (or the slightly larger version offered if your close to the limit). The Guillemot and Night Heron are both very flat-bottomed boats. Thus they are more prone to drifting downwind in a crosswind than a rounded or V-shaped hull.

I weight 155 or so, and found the Night Heron drifted much faster than the kayaks of my kayaking buddies.

The Guillemot is also a very sexy boat. You won't be able to pump gas without talking about it.
