I trying to track down the last of my deck leaks that run down to the ice box area by running a hose over different spot on deck. I'm not up to the companion way and found a small drip onto the sink when I run the water into the sliding companion slot. There also seemed to be the same drip when I ran the hose over the traveler. I would like to take out each traveler bolt/screw/?? and rebed them, but I'm unsure on how they attach to the boat. Are they regular screws without a nut on the end or is the nut embedded into the deck?
