Oh that barrel reference brings back memories. Spent a few years in ships in the merchant marine.
My classmate was on another ship and was benching, ship took a big swell and you know the story. Barbell came crashing down. Fractured his clavicle while at sea. Very painful few days while he stayed in his rack as the ship continued steaming until it got close to shore and could mess ax him.
Not a sea strong, it happened. On merchant ships there is no sick bay nor medical staff. Oh good times.
