My 2c would be to get something with dedicated drivers, not bits that could get dropped overboard.
I would recommend a Wave+. I would also recommend something like this First Mate Knife that has a marlin spike for knots and a shackle key.
I wonder... are there any plier-based multitools with a marlinspike?
And maybe something that can handle exposure to (salt)water, like a Swisstool or Spirit.
SOG made the West Marine Sailing Tool:https://forum.multitool.org/index.php?topic=21299.0But these are pretty hard to find these days.
Thanks…based on my research and your recommendations, I am going with the Spirit X and Victorinox Skipper or Skipper Pro.
