Little seacoast, You are surely correct here, upon closer inspection, it is clear that only one sailor is hauling that shell up from the hold. Four lines go thru the blocks, yielding a mechanical advantage of 4, therefore 133.5/4=33.37 lbs. Even with friction from all sources, a lift of around 50 lbs. is certainly well within the capabilities of almost any sailor who was extremely used to hauling on a variety of lines every day and lifting things much heavier than 50 pounds.
Thanks very much for pointing that out,
Mike and Tracy
