I recently saw a fish basket that hooked over the side of a boat, I knew where some items were that I thought I could construct as good or a better one from so here it is. I took an old hoop net an cut it down, used 2 rings and tied the bottom under the second ring. I hook it over the side of the boat using the oar lock, I originally had a pin welded to the top ring but it bent the ring with a lot of weight so I attached a small chain to one side and then to a pin. The opening is 26 inches and it is 5 feet long. Even the big one go in here and stay. The great thing is you take your fish off and toss them in the hoop - no hassle. The attachment show it with the boat on the trailer, but you get the idea.
