Check this out....put my yak in the LMR this morning and it begins slowly filling up with water. I am fishing and think, that's weird, so I go to the shore, empty it out and inspect the boat.....I see nothing wrong after a quick look. So, I begin to fish again, as if the water earlier just magically appeared. Again, I notice water slowly filling the boat. This time I am much more concerned. I have flashbacks of the movie Titanic. Did I hit an iceburg? Turns out there is a small slit, inch long at most, along the bottom of the rudder of the boat. Most likely from dragging across these shallow rivers. I got an epoxy gel and filled the hole as well as coated the rudder section of the boat. Do you guys think this will hold? Is that stuff waterproof?? Anyone ever have any experiences like this?
