In this article were going to talk about lowering a mast when no crane is available. For example, perhaps your vessel is in a remote location or perhaps the cost of a crane is out of the DIY budget.



    The steps to unstopping a mast without a crane are:



    Estimate the weight of the rig to be lifted

    Find a structure to lift from

    Attach the lifting rig to the mast

    Lower the mast to the deck





    Estimate the mast weight

    Start by estimating the weight of the mast you plan to lift. You migh...
