For the minimalist who doesn't want a skeg, but when in doubt can whip it out.

I made the skeg plate from 4 mm plywood and laminated it with carbon fiber. One of the straps is positioned against deck fittings to keep the straps from sliding backwards. The skeg is close enough to the cockpit for me to adjust it myself. However, the skeg has to be strapped on while on land or by another kayaker on the water. Because the skeg is not parallel to the keel, there is a slight ruddering effect, which makes deploying it on the weather side necessary. This skeg design works best on four-panel hulls.
