If you can't control the boom, leave it trimed in and secure as best you can, you'll still have the advantage of having a multiple part block and tackle to give you LIFT against the MOB's weight.
As I see it, using the boom presents two potential problems:

1. On many boats the boom is too low to lift someone high enough to clear to lifelines and swing them aboard.

2. To really take advantage of using the boom, you need to swing it out so that the MOB is kept clear of the hull but still control the swing. On most boats that requires running a line forward, like a preventer, so that the boom can be restrained between that and the main sheet. Could be quick and easy or slow and difficult depending on the boat, crew and level of preparedness. Just leaving it sheeted without a second line , pulls too horizontally so the MOB isnít clear of the hull. In those circumstances I think you would be better of using a halyard so that the lift is more vertical. You can use a winch to gain some mechanical advantage.

If you plan use the boom, you need to have tried it out on that particular boat before you really need to use it. It might be a great method for you and your boat but it might not.
