Atlantic 85 Louis Simson

Skerries ILB, number B-866,  is called "Louis Simson"  of and is a B Class Atlantic 85.

The lifeboat which went on service in February was funded by a 75-year-old legacy from the late Charlotte Jordan Simson in memory of her husband Louis.
Charlotte who hailed from Salem, India, married Louis Simson, a native of London, in 1882. The couple relocated to Tasmania where Louis was a mining agent and stockbroker. Following his death in 1922, Mrs Simson returned to the UK where she lived in Paddington London until her death in September 1938. Mrs Simson made provision in her will for a trust fund that would provide various relatives with a modest income for life. She arranged that, once the trust fund had come to an end, the remaining money should fund an RNLI lifeboat to be named in memory of her beloved husband.

Fast, manoeuvrable and reliable, the B class operates in rough weather conditions, capable in daylight up to force seven and at night, to force six winds.

The new lifeboat, an Atlantic 85 is the latest version of the B class, introduced into the fleet in 2005. She is powered by two 115horsepower engines and has a stronger hull and greater top speed than her predecessor the Atlantic 75. The added radar allows the crew to operate more effectively in poor visibility and she also has VHF direction-finding equipment.
The vessel also has a manually operated self-righting mechanism which combined with inversion-proofed engines keep the lifeboat operational even after capsize. The lifeboat can also be beached in an emergency without causing damage to its engines or steering gear.

The Atlantic 85 carries a full suite of communication and electronic navigation aids, as well as a searchlight, night-vision equipment and flares for night-time operations.
