I really like to kayak whenever I get the chance.
Kayaking looks fun! The difference between canoeing and kayaking is the sitting position of the paddler and the blades and the amount of blades.
Have you been kayaking or canoeing before? Both are very fun to do.
I have never done either! lol Kayaking is really low to the water in a canoe like boat where the person sits forward using a double paddle to pull front to back. It sounds like work! lol
Yea kayaking is very tough on the arms since you have to constantly move your arms up and down.
I imagine it is a great work out! Most kayaks have closed decks and there are also sit on top and inflatable kayaks available. 
I did not know there were inflatable kayaks. Do you know when regular kayaks became invented?
In the mid 1800s the kayak became popular and the Europeans gained interest.
