Afterguard:

Maybe it’s just because I enjoy sailing, but this was a cool term.

In modern usage, the loose assemblage of skipper, navigator, tactician and other thinking types in the back of the boat. Generally: The strategic team within the crew, in control of the balance and course of the boat.

Originally, it was the seaman  stationed on the poop or after part of the ship, to attend the after-sails.

Thanks.
