An Eye for Detail In Lifeboat Design

HERE ARE two mooring fittings for afloat lifeboats, developed in the RNLI design office from long experience. (Left) Stemhead fitting: designed for use on cold, dark nights, with good finger-holds and nothing 'fiddly' about it. Cast in corrosion-free gunmetal (BS1400- G.l.-C), it is trouble free, will last the boat's lifetime and rarely needs more than general maintenance. On each side is an opening fairlead. To close, the opening section (r.) hinges down, its rounded end engaging on the spindle of the flap (!•)• When the flap is hinged down on top, flush, the fairlead is locked. The central roller takes the mooring chain, which is made fast to the sampson post (right) with a slip link.
