As you might imagine, your question has been asked before. Use the "search" button on the dark blue bar above. I typed "what kayak?" in the advanced search line and on just this forum got 100 threads. Some were off topic, but many were from new entrants wanting advice. The accumulated wisdom is building up after years on this forum. Take advantage of what's already here. Note, too, that a couple of the SPONSORS
of this board are kayak dealers. I realize that they're a long way from your home waters, but at least one, Billington Sea Kayak, is extraordinarily service-minded. If you were to call and mention the board, you might be able to schmooze a little and narrow your search before you start to test paddle. Good hunting.
