I also work that same schedule. It is hard to thi k you can compete with guys that get to handle their guns everyday. I just try and shoot as many matches that I can when at home. This off time fortunately gives us that option. I usually will pick one, maybe two things to work on during off hitch. As for on the boat, I try to do some visual exercises. Kind like simulating transitions and stuff, mostly with just my hands. Sent from my SAMSUNG-SM-G891A using Tapatalk
