I've borrowed Andy's Hobie Sport a few times, and I love that thing.
It takes a little while to get used to not having much kayak in front of you. For being such a small boat, they sure are capable little yaks.
It was silly how easy it was to get the yak to and from the water. The fitted hull only weighs about 55 lbs. It won't track as well as a longer kayak, but I never found that to be an issue because you steer with the rudder anyways. I was surprised at how dry it was too.
If you are primarily looking to get out and cover some serious distance in the ocean, there are better kayaks out there. If ease of transporting is your main concern, the Hobie Sport is a pretty versatile & fun yak.
