snap, crackle & pop

On a 6 day trip, we noticed a crackling sound from 2 of our kayaks. Mostly when paddling on flat water. At first I thought it might be water intrusion into the wood, due to a road rash incident, sealed with epoxy right before the trip. But my brother in law also noticed the same thing. Does anyone have any clues?

 Glad you posted this. We paddle mostly brackish water and hear it too. Also hear 'drumming' and 'croaking' from below the boats that I know are fish related so I assumed these 'clicking' noises were shrimp. That's my best guess. I also have a wood skiff with the same noises, I remember her check out splash - I thought it was coming undone!

I thought it would be funny to splash my paddle when a dolphin was patrolling close by. I had forgotten that the dolphins in the everglades are very accostomed to kayaks and like to play with them. I wasn't surprised that the dolphin turned towards me, but the he ramped up the speed and charged my 17LT. He ducked just under my boat, leaving a big splash and hole in the water, I almost rolled over.
