Even when the waves are flat, water dripping off the ends of the paddle gets blown onto the deck where it runs into the sunken area around the lip of the coaming. I'm a bit mystified as to how so much of it ends up in the seat though, I guessed it was a combination of wicking effect where it gets sucked in between the edge of the skirt and the lip the skirt is supposed to be sealed onto and simple leakage through the fabric of the skirt itself --- it's just a $40, Seals, coated nylon cheapo. Also, there's a seam on the rear of the coaming lip, that although it doesn't leak itself, it's not smooth --- there's perhaps a millimeter drop between one side and the other that of course the skirt can't completely seal onto , maybe that's it. But if you look at the part of the skirt that's supposed to seal onto the lip, it's just a stretchy cord inside plasticized fabric with a coating on it --- it's by no means completely watertight like a drysuit seal would be.
At first I thought if I wrapped a towel around the coaming it would help, and it holds it off for a while, but only til the towel becomes saturated, and I can't be bothered wringing out the towel every 15 minutes. I tried rain gear, but the water runs down my wrists and as soon as it starts getting my shirt wet and the wick effect distributes it all over my upper body. Even a single wave from a wake that puts the slightest slop of water in my lap ends up soaking my shirt also.

My question is: Would a better skirt (the neoprene skirts seem more expensive) help, or does everybody just accept getting wet as an integral part of paddling without a drysuit?
