If you are looking for furling convenience and don’t have or don’t want the extra cost of a furling mast, a furling boom is the choice to make. Several companies make booms that allow a full-batten main to be rolled into the boom. These mains have all the benefits of a standard Batmain, yet they can be roller reefed or furled into the specially made booms. And at the end of the day, there is no sail cover to put on since the sail is protected from the sun inside the boom.
      Furling booms offer a huge safety benefit over any in-mast furling sail, in that if the furling system jams or fails, you can always drop the sail to the deck and get it down. If an in-mast furler jams, you are stuck with some portion of the sail flapping in the wind.
      Furling booms work well for large boats where the boom is too high up to furl and cover the main. This can be a retro-fit on an older boat or it can be specified on a new boat.
     Furling booms are an expensive upgrade and your existing mainsail cannot be retrofitted.
