Start a Wolfpack with two subs and practice approach drills and plots on each other, taking turns.
But I've had conversations with others who didn't want to train each other, didn't want to man their assigned station and didn't want to practice drills or nav plots but who then complain there's nothing to do in the 20mins - 1hr it takes to get into position.
/smh I know, I know... but they're the ones who advocate time jumps and time compression to get out of the "boring bits" to the "action" bits.
