Ocean kayaking is a different experience from river or lake kayaking. Ocean kayaks are larger than river or lake kayaks. The water can get very choppy when compared to a lake, and you don't get the same freedom to deal with rough water the way you do with a tiny river kayak. Have you ever been? If not, would you go, given the chance?
I,ve never been kayaking in the ocean, but I have in the port river with an instructor, my husband bought me a mother's day outing, and it was great fun, and ofcourse I got to see the dolphins, that was my hi light.
