Normal
On helicopters they go by weight and they will charge extra for people over 250 and ride with one less in the helicopter. As far as kayaking goes I did the kayak tour in Ketchikan in 2001 and I weighed 265 at the time. The only problem I had in the kayak is that I have long legs and have bad knees so it was uncomfortable for my legs. I fit in the kayak fine and was able to move around fine. We had a great time.
