Is this the smaller of the two tomcats? I originally ordered the smaller one. I am 5'5 and weigh 110 pounds. However, I was planning on using the boat in class 3 and 4 whitewater and decided the smaller one was too small and not stable enough for big rapids. I ended up exchanging it for the larger version. If a person were using the smaller tomcat on flat water I would guess that it would work well for anyone up to about 175 lbs. I hope that helps.
