Gaz:

Great question.  More aerobic volume is always going to help even if it’s not super specific.  Especially if these activities help you avoid injury.  We have coached some ship-bound athletes in the past and one thing we had them do was use the stairs/ladders on the ship to accumulate more aerobic vertical.  On your rucking day, you might want to include some vertical under load.

Good luck,
Scott
