Climbing the mast of a sailing boat represents a challenge for many, primarily for the person climbing, but also for those below, as they bear the responsibility for the climber’s safety.
An essential accessory is a good boatswain?chair. There are fundamentally three types available on the market: with a seat board, without a seat board, or in a harness style.
The choice of type is subjective and is influenced by the nature of the climb; those who are more experienced in climbing and less passive will typically use a harness, while those who will be climbing for work or intend to hang for longer will opt for a banzigo with a seat board.
It is crucial to assess the quality of the two halyards connected to the banzigo, which should preferably be tied with a bowline knot. The two halyards will be distinguished as the main and safety lines and should, if possible, be handled by two separate individuals. Carabiners, if not specifically designed for this use, should be avoided due to the risk of accidental opening.
It is also important to evaluate the condition of the blocks at the foot of the mast, the organizers (the lead blocks), and the winch that will be used to reduce the effort of those hauling.
Coordination and constant communication between the climber and the person on deck will be essential to avoid getting entangled during the ascent and subsequent descent. It will also be crucial for the rest of the crew to stay clear of the base of the mast to prevent any tools that may fall from hitting anyone below, and it’s likewise important for the crew to move as little as possible to prevent the boat from rolling.
It is important to practice these maneuvers in port without the stress of necessary interventions to be prepared in case of need.
If using an electric winch, which is certainly convenient for speed and ease of effort, greater attention must be paid during the climb because the winch will not stop if the climber encounters an obstruction.
The ascent should always be carried out with the stopper closed and at least three turns around the winch. The descent should obviously be conducted with the stopper open and two turns around the winch to ensure smooth movement without jerks for the person above. However, during the descent, given the open stoppers, maximum concentration from the operators on the halyards is necessary.
