A week ago my sweetie and I were out paddling) on the river in our wooden double sea kayak (a Pygmy Osprey). Every now and then, it would vibrate, and make a deep buzzing sound. (No, I am not making this up.) After the fourth or fifth vibration, we noticed it coincided with the horn blast from an upriver ship, no doubt bleating in the thin fog. The ship was out of sight behind some islands, and probably at least two miles away. The horn blast was actually quite faint. My conclusion was that the large open space connecting the two cockpits was resonating in sympathy with the note from the ship's horn. I guess I should not be surprised at this, although at first it was very eerie. Has anyone else had this happen to them? -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Only when the replica of Cook's Endeavour fired a cannon across my bow, a glass boat and it and I resonated !!! As far as I remember when she did it when paddling my wooden boat there wasn't the same effect.

The wierd thing was that I'd hear one more "thump" after I quit stroking. It took the longest time to figure out that it was a half-full water bottle rolling around on the knee shelf. -- Wes --------------------------------------------------------------------------- Wes Boyd's Kayak Place http://www2.dmci.net/wesboyd/kayak.htm Kayaks for Big Guys (And Gals) | Trip Reports | Places To Go | Boats & Gear --------------------------------------------------------------------------- *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Dear Dave and all, I too have heard strange 'resonances' conveyed through the hull of a kayak. My brother's three-hole nylon-covered Kodiak baidarka emitted 'pops' and 'clicks' as a freighter passed us by on the Columbia River. It was not the thrumming of the engines. . . . . just a wierd clicking. I've also noticed this when rolling near motorboats-- especially when wearing a neoprene hood. (Say. . . .is it just me, or do neoprene hoods hamper one's ability to hear conversation while at the same time greatly ACCENTUATING the roar of jet airliners?) Anyhow, I'm certain this is just a 'Columbia River thing', as Dave likely has also come to realize.

Yeah, it's the ghosts of long-dead gillnetters, moaning to be released from the sediments the Corps of Engineers piled over their watery graves ... [insert the Twilight Zone noise]. Can somebody do the calculation and find out what the natural frequency of vibration would be for the cockpit cavity of a double?

Dave, I too had a strange vibration and low buzzing noise when I first bought my CD Gulfstream and had had i5t for about 2 weeks.. At first it appeared to be related to whether or not the skeg was down and I was attributing it to the skeg vibrating from quartering seas while it was deployed. The previous owner of the boat assured me that he had never had a vibration or grumbling sound from the boat. It took a while, but I finally solved the mystery. I had been keeping my paddling jacket in the day hatch and putting a water bottle in on top of it. The weather had warmed up and I stopped carrying the paddling jacket. This left my RIBBED water bottle free to roll around with the swells and the ribs were producing the vibration and noise. As soon as I changed water bottle, the vibration and noise left.

My Libra always hums a beautiful, warm tone when it is going really fast down the face of a wave with the rudder down. We know we've got a good surf when we hear the boat singing.
