I have been using my Colorado since 2005. It has held up great. I use it alone with my 20 lb terrier. The fabric is highly durable and won't be punctured by claws. When I use it alone, I find it useful to throw a few big rocks in the bow. That makes it track better overall, but especially in winds. I have been caught in high winds and the boat is very stable. It is light weight though, so I cannot fight the waves and wind. When the wind comes up I head for shore and wait it out. This boat is hard to get back in when in the water so it is best to do you swimming from shore. If you dog likes to jump out of the boat, get the dog a life jacket with a handle on the back. That makes it easy to pull them back in if needed. I also have the single version Rio. I have to admit, the Colorado is superior. If you put in a second person though, have the front person do the rowing. The best paddle for this boat is a double blade oar.
