Hey! I've done most of my dives on Maui, Lanai, and the Big Island, but I will be heading to Kauai next month and am curious about these two dive operations, and which would be best for my needs. From what I already know, it seems like a draw. I've seen a picture of Seasport's boat, and it looks nice. I like that it has a top deck (Strangely enough, I don't get seasick if and only if I sit on the top deck, and I know that Kauai's waters are not as placid as, say, those off the Kona coast), but Fathom Five's website doesn't have a picture of their boat, so I don't know how big it is, top deck, etc. On the other hand, I suspect that Kauai, like the other islands, usually has way calmer waters in the morning (please correct me if I'm wrong), and Seasport's morning dive seems to be for advanced divers. It says in the brochure that they may do a drift dive, which I've never done before and am not comfortable with it, so I'd have to go in the afternoon--the downside there is the rougher waters and the shallower dives (I like to dive deep and am working on my Deep Diver PADI specialization). Fathom Five's morning and advanced dive had no specified difference in ability level, so I would be able to go in the morning if the AM in Kauai is calmer. Any suggestions for me, advice or personal experiences with these outfits? Any other info on Kauai diving would be greatly appreciated! I dove a couple of months ago in Kona (saw white tip reef sharks and manta rays!) and Lanai (Cathedrals I and II were amazing!) and can't wait to be diving again in the Hawaiian Islands!
