A Choppy Night

I really need to sit down sometime and get a better understanding of how waves form in the river. Some nights a fairly strong wind will kick up nothing but some small swells. Other nights a moderate breeze will somehow stir up serious wave action. Last night fell into the second category. From conditions on land I really wasn't expecting any significant when I got on the water. But boy, it turned out to be a fun evening. We headed across and downriver, always the roughest of our paddles and quickly ran into two foot swells with occasional whitecaps. Nice! In cold weather these kind of conditions freak me out because of the serious implications of capsizing, but once the water warms up (it's now in the 70's) I love a choppy evening. Downriver we paddled straight into it. A lot of kayaks have a very buoyant bow and so they go over top of the waves when you paddle into them. That keeps you dry but pounds you every time you drop down into a trough. The bow of the Shearwater cuts through waves rather than going over them. That means a wet experience with waves rolling up the deck, but a fairly smooth ride. You just have to know how to steer the thing - there's no point in trying to turn the boat when the nose is buried in a wave. One new paddler turned back (escorted by a couple of more experienced kayakers) but the rest of us made it down to Haines Point, which turned out to be surprisingly calm. In windy conditions the point is often a mess of standing waves and clapotis caused by the confluence of two rivers plus the channel bouncing into the seawall, but for some reason last night it was relatively smooth - again, there's some hydrodunamics at work that I just don't understand.

Paddling in following seas (the waves behind you) is very different than paddling into the waves. A wave will come up on you and all of a sudden the stern of your boat wants to go faster than the bow, making it want to spin around. Proper strokes and use of the skeg can help, but I always find it a weird feeling. On the plus side, the waves really push you along - we made much better time on the way home than on the way out.

There's never an evening when the power of nature fails to impress me. On the evenings when the river is up it impresses me most of all.

A Tale of Four Jess's

 Jesse is not all that common a name, and so unlike the Toms, Davids, and Bobs of the world I don't run into much name confusion. So it ...
