. Then it would be a must as you would need a solar still and the tarp would be the best for that with the pot. So perhaps I'm wrong and should swap the tarp with the fishing rod as odds are a bunch of line would wash up at some point (any remote beach I've been to seems to have line on it) and you could fashion hooks from scavenged material. That said I'd probably go saw over tarp for ability to build, but that would be a long term vs short term Benefit if you survived that long. Anyway...no right answer. I just replied to your as I thought it was one of the best, not just to disagree.
