Can't beat Aire's 10 year no fault warrantyon the Lynx (a very stable boat), most others have 5 years,still quite a while for a boat. Aire's tributary line of boats is also quite good (5 year warranty) the Strikes use a Urethane bladder like their US made boats. Tomcats aren't bad, but do have a exposed sewn seam on the boat that will wear over time if not protected with Aquaseal, and vinyl bladders that are not as durable . I'd stay away from Sevelors, they don't bail that fast, and are not the same quality of hand made boats. Try to stay away from boats with glued seams, eventually the glue will fail, and have to be repaired, most boats now use welded seams though.
