One week ago I concluded an adventure that twice took me from Tennessee to Minnesota. My quest was for a Lund boat; one not normally seen, or offered for sale down South. Last Sunday I found the one I wanted and bought it. After I got it home ( a 1023 mile trip ) I started making some repairs to the coupler and winch. Both were replaced. Yesterday as I was installing the new winch, I noticed a small one inch square grid pattern of uniform black specs on the red hull of the Lund. I ran my nail across it and was surprised to see that I was able to remove a portion of the specs quite easily. I suspect they are some form of eggs laid by some creature, but what I do not know. I have not had the boat in the water yet, and will not until it is pressure washed. Do any of you have any idea what these specs could be?
