Boom brakes allow the mainsail to still move, but reduce its speed to one that eliminates most chance of injury from the boom crossing over the boat. A boom brake doesn't allow the boom and mainsail to store up great amounts of energy, like the preventer can. A boom brake also isn't as likely to allow a situation where gear is damaged or the boom is broken.
Excellent advice.
