I really like my Catalyst 13. This is my second yak; my first being the smallest Mainstream on the market. As all have indicated, the boat is quick and glides very nicely. I also play frisbee, and I use spray silicone on the underside of my frisbee to make it easier to spin on my fingernail. I decided to try some of the spray silicone on the bottom and sides of my boat, and the increase in speed is noticeable. I later tried the spray silicone on all parts of the boat except the inside, and it gives the boat a deeper red and a nice gloss. This is a really good boat; I've used it in many different weather situations (including in winds over 20 knots, and I find I don't need a rudder at all.
