Had to make due. +BrookField Angler told me to go to the pet store and purchase foam balls found in the cat toy section. I went, but did not like the sponginess of those balls. (I just laughed.)
Today when I was walking around Walmart, I seen the answer to my scupper plug dilemma, in the form of foam/spongy yellow practice golf balls. They were not as squishy as the cat balls, so, I think they will do a better job, and for $2, how could you go wrong. Worse comes to worse, I could make a floating key chain for any small tools, or keys with those foam golf balls.
4 Pack Foam Practice Golf Balls - My local Walmart had a 6 pack for $2....I have 6 scupper holes. It was destiny.
I also, scored a milk crate at work. Slowly but surly I am modifying this yak to my liking, and on the cheap!
Next project...sealing those 2 hatches to make them water tight. There was some water that came in with the rain we had the past 2 days. Not much, but it's supposed to be a dry hull....not a wet one.
