Yes, I am very unclear on this too. Perhaps they haven't really thought their way through this yet?
I would *think* it's based on the number of sinkings in ONE trip (whether you dock or sink); otherwise, how can it be fair if someone is available to play all 3 days, 8-10 hours a day, compared to someone that perhaps only has 2 hours available on just Saturday, for example.
Is this "top score" based on an individual's performance or total crew performance? Meaning, could someone potentially just be afk on someone's ship and do absolutely nothing but yet win a prize? Not that *I* would even think of doing that...

I would hope that's not the case. I would think to be fair, once again, it would need to be on an individual performance, not on a crew performance...
MORE INFO PLEASE, DISNEY!!
And by the way, to answer your question, YES, I'll be here! My weekend is pretty clear, except for a few errands to run here and there, and of course church services on Sunday... but other than that... I'll be privateering!
Who else?
