It definitely takes experimentation, and it takes experimenting with the fishermen.
We've not fished this on-demand gear in 800 fathoms of water, so what you're saying is exactly correct. There are a lot of challenges and stresses that are involved in those kinds of fisheries, especially if you have 800 fathoms of buoy line and you're probably fishing a two-to-one scope, so maybe you have 1,600 fathoms of buoy line. That is a lot of rope that can entangle whales, and maybe not even right whales. Now we're talking about northern bottlenose whales or sperm whales as well. It is a long piece of rope that whales are going to be able to run into and bend.
I know it seems like an immovable object to little weaklings like you and me, but a 50-tonne animal that runs into that rope is going to find itself capable of winding that up.
What is the solution to that? It's not clear. It can only be solved by testing, and involving fishermen in the testing. We could find out if this on-demand stuff works or not.
