Hey. I'm not really qualified to answer your question as I am only a beginning kayaker. However, the first place I look for help with any outdoor type purchase is REI. Their website has great comparison tools and their in store help usually have lots of experience. Check out their selection of sea kayaks http://www.rei.com There's also a how to choose a kayak section http://www.rei.com Like with any sports equipment it really comes down to personal preference. I recommended a tandam kayak I've used before that worked great for me. Hope this helps.
