While there are many ways to go aloft, the most common for cruisers is to use a bosun’s chair connected to one of the main halyards. This method requires a crew member with the brawn and willingness to crank you up the mast, which can take a long time. In addition to being physically demanding, mast climbing is a dangerous job where a single equipment failure (like a halyard or bolt holding a winch) can be fatal. To reduce the risk of this happening, the climber should aggressively bounce-test their setup before they go up. This shock loading will ensure that the halyards and other equipment are not stretched out, and will also allow the climber to hang on in case something does let go.Go here :https://mast-climbers.co.uk

Maximizing Efficiency with Mast Climbing Work Platforms

Another method, less commonly used by cruisers but popular amongst cruising riggers, is to use a pair of ascension devices with a static line threaded through each. The climber sits in the chair or harness attached to the halyard and, when the halyard gets slack, transfers their weight over to the static line. The climber then stands, pulls the stirrups up higher and continues this process to the top of the mast.

These systems are also known as mast climbing work platforms (MCWPs) and are based on mountaineering techniques. They are used by construction workers on tall structures to get to elevated or hard-to-reach places for a wide variety of jobs including sign installation, facade cladding materials, HVAC and electrical maintenance and painting, and bridge inspection and maintenance. It is thought that these systems are inherently safe but the exact performance of this gear under specific load conditions remains undetermined.
