I love kayaking, it requires the use of a kayak as you can imagine, which is a small, narrow watercraft.
Yeah I've seen them, can you tell me more about them.
They have an interesting history, they were actually used by the indigenous Aleut, Inuit, and Yupik in the subarctic regions of the world.
Really, how old is the kayak.
I don't know exactly, but if they were used by the Inuit and even Ainu, probably at least a thousand years old or more.
Yeah they must have been around for a while.  Do you know why they were made for?
Well if they were used by hunters I would assume it's because they were easier to build and manuever than a full-sized boat, and they probably hunted fish with them.
That makes sense I know they are small so they can fit in shallow water were bigger boats cant make it. 
Right, modern kayaks are also being sailed now even by using small electric motors as propellors.
