Thanks Jim. Up there in Puget Sound, you're in a kayaking mecca of your own!!
With the right drybag(s), you can keep your gear dry even in a SOT (Sit-On-Top), esp if you can stuff some of it inside the boat. This goes for tripods too. You can also "double bag" it .. can't hurt!
When actually on the water, it's a challenge to keep expensive gear dry and salt-free in use, so I always have a small bladder of tap water to rinse my hands off from the salt before handling the cameras. Realistically, a waterproof cam (or a housed cam) will take 90% of these pics on the water - bust out your good gear when you make a landing .. wherever that may be!
Here's a lil bit more on that island, if you're interested:
