Ryan, I replaced all of the no-skid on my boat last year. Here is a link to the manufacturer. I got the name of these guys from the folks at Triton in Tennessee. This is who manufactures the no-skid for their boats. The one I have is the 'jelly bean' shape about 2/3 of the way down.
The original piece was 37" by 74" and I have about 37" by about 48" left. The 'jelly beans' are about 7/8" by 1/4". This already has adhesive on the back, so all you do is cut the shape you want, peel off the backing, and stick it in place.
If you want it, just make me an offer. I will be in Miller Grove (near Quitman) this Saturday if you want to meet.
