haha, well, Kevin's kayak had some problems, but I know how to handle those now
Erika, it's pretty easy to do this. I've got 2 kayaks, so I sometimes take people out and show them how to do it. They are both the sit-on-top style, and you pack up your gear and tie it down to the front and back of the boat, and wear your wetsuit while launching.
Launching it can be a little tricky, but I just drag the kayak into the water, pull it directly into the surf (if any is present), keeping the bow up, and then I hop on and begin paddling like mad.
Easy as that! Once you get to the spot you want to dive at, you toss out your anchor, hop off the boat, and begin to gear up. That can be a little tricky, so I like to have the simplest gear set-up possible. The less lights, clips, etc accessories, the better, at least for the first few dives.
Anyways, once you're geared up, you descend down the anchor line, check it to make sure you are secure, and begin the dive.
It's really incredible to dive this way. I've found some really lovely spots off the beaten track. Kayak diving takes more work, time, and a lot more energy, but you're doing something that very few other divers ever do.
Southbayren: I still haven't figured out how to kayak underwater yet. Once I master that, I'll get back to you.
