If you are considering putting a sail on your kayak or canoe, recognize there are a variety of options out there. Some look like no more than an umbrella. A couple, like a "V". There are at least three designs that are true sails, with the familiar triangular shape formed by a mast and a boom. You should consider no other design! The umbrellas and V's are just not true sails, they are for downwind use only (more or less). How often does that happen? A true sail will enable you to paddle into the wind at a pretty high angle. Don't waste your money on a crappy sail, only to upgrade to a better one later and leaving all kinds of unused holes and hardware from your old sail on your boat. Just buy the best from the start!
There is no doubt in my mind that the Falcon is the best. Best design, best materials, best customer service, best performance, you name it. I'm not affiliated with Falcon sails at all. But I put one on my Kruger Sea Wind, tried it out a couple times, then raced and won in my class, the Everglades Challenge 300 mile event. The Falcon was a big part of that!
The sail is just a piece of art. Carbon mast and boom. CNC machined aluminum U-joint at the base of the mast. It comes complete with everything needed, down to the last pad eye, cleat, nut, washer, and bolt. Patrick Forester provides excellent customer service and is an experienced kayak sailor himself. The Falcon is also built right here in the USA. It hands-down gets 10/10 and smokes the competition.
