That's why they call it the "Boom"!
On a small, single-masted ship, the sail will be large and the deck so small you have to watch for the boom—it's the spar under the sail. So when the sail moves, it's likely to swing suddenly across the deck and knock the sailor unaware in the head. Sometimes this results in unconsciousness. Sometimes the sailor is knocked into the water. And sometimes, the sailor is knocked unconscious into the water.
In some cases, the target of the boom will get a warning that it's coming... but usually the warning comes a mere second before the impact, doing the target no good whatsoever.
Very much Truth in Television. When the boat is jibing (changing the sail orientation by moving the stern into the wind, as opposed to tacking, turning the bow into the wind), the boom can very suddenly swing across the deck at high speed, which can lead to a concussion (or worse) for anyone not paying attention. Keeping your head down is one of the first things taught to beginning sailors.

- There is a minor piece of Polish internet lore which is a humorous dictionary of nautical terms. The dictionary mentions that the boom's main purpose is to sweep landlubbers, annoying crewmembers and miscellaneous litter from the deck.
