The Windpaddle is a pretty durable and fun change up for longer trips or enjoying windy days. We tend to use it after the first six miles in a narrow wooded trip down Riverbend, once the river opens into tidal estuaries, and around Jupiter inlet on windy days. The sails luff a little bit until you learn to cinch down on the rigging with the turtle that sits at the six o'clock position. It's more helpful to have a rudder, but if you know how to edge and the wind is generally behind you, you can get by with fewer correction strokes.
All in all, the sail is durable, easy to stow, and is a good time when you just want to relax on the way back in or during a longer trip.
