Do you like to Kayak? 
I just went rafting the other day which is kinda like kayaking, which is using a kayak on moving water.
But a kayak is certain type of craft though.  
What do you mean by craft? It is different from something like canoeing by the number of blades on the paddle.
A kayak has a certain look. A raft does not equate a kayak. 
Ohh raft, yeah I know rafts are different since kayaks are low to the water and more canoe like.
I want a ocean worthy Kayak. 
I would love one of them too. Most kayaks have closed decks which seems good for the ocean.
