Designed to keep the bigger waves out and the warmth in on a cold day. Designed to fit all Advanced Elements kayaks with an inflatable coaming.
I've only briefly tried this, because the water has been so hot that a little splash from the paddle doesn't hurt. It goes on just fine, but make the adjustment to the opening of the canoe carefully. In particular, the grooves in front and behind the opening on the side of the canoe should be covered so that the shape of the edge of the opening is preserved as well as possible. Otherwise, it may come off too easily. from the points when there is a small jerk.
A little tricky to get in place in the waves. Otherwise works well.
