Nav Mast Climbing Kit

Harken Nav’ Mast kit, a compact and rapidly deployable solution puts crew safely on the spoSituation:-

Growing demand for 24/7 connectivity to telephone networks, broadcast media, and high bandwidth internet links is resulting in nav’ masts festooned with antennae and dishes in order to keep superyacht owners and guests in touch with the world. To ensure good satellite and data links, antennae are best located at height, clear from obstructions to radio signals caused by the ship’s superstructure. The result is an increasing need to carry out tasks that go beyond the routine of servicing a ship’s nav’lights.

Problem:-

For the crew of superyachts, the increasing height of nav masts (in line with the trend for ever-larger vessels), the increased density (and complexity) of antennae and satellite dishes, and the frequency of visits to the masthead, are making the task of working at height on nav’ masts more demanding. To work effectively, crew need to be able to safely ascend/descend and tether securely at the best point on a mast to carry out the required services, and always with safety cover present.

Implications:-

Nav’ masts are often designed with a ladder in place; however, most are not. At the masthead, the forward motion of the ship through the water is accentuated, testing even the best sea legs and accentuating the consequence of a fall from height.

Solution/Benefit:-

During the recent commissioning of a 70-meter superyacht, a member of the crew recognized the need for safer, secure access to the nav’mast. “We recognized the need for a fit-for-purpose solution to safely raise and lower crew members up the ship’s nine meter mast to service navigation light and antennae. At nine meters off the deck, movement at the top of the mast is exaggerated to that of hull. With limited options as to where a winch could be mounted and no options for the winch and rope to be left in place; we approached Harken in the UK for a solution. We wanted an off-the-shelf solution that was fit-for-purpose, self-contained and ready to go.  Harken’s LokHead winch kit fit the bill for a quick set-up and easy lifting.”

The Harken Nav Mast Climbing kit shows adherence to MCA regulation MGN410(M+F) Work at Height Directive, which relates to the provision and use of appropriate equipment for tasks such as mast maintenance.

Product:-

Harken as part of its commitment to its Safer at Sea campaign, has created an easy-to-deploy mast climbing solution.

Supplied complete with a harness, back-up safety device and extension sling, all of which will be stowed away in a Harken compact bag, the Harken LokHead winch kit comes supplied with its own hard case.
