In reply to Erik B:
Hi Erik
There's not really any single top end kayak to recommend, it more depends on what you want from it. A boat perfect for paddling to St Kilda will be different from one better suited to exploring wee nooks and crannies along a coast. There are a lot of boats out there that will do all pretty well though. Different folk like different boats, best thing to do is try to get to a sea kayak symposium, or join a club and hog as many shots of peoples boats as possible, just to get an idea of what you like and dislike. I'll have a rake for some links that may be of use and post them later.
In reference to a comment above, and to a current trend for plastic boats, my 2p worth would be to forget plastic if you're planning to get really into it. GRP boats are lighter, stiffer, faster, infinitely repairable, and importantly imho, they just feel and look better.
And make a Greenland paddle.
