'Ralph and Joy Swann' and the boat which replaced her the Trent Class 'Stanley Watson Barker'

Here are a few of the major improvements incorporated into the replacement boats listed below. They all have a top speed of 25 knots, which is at least 10 knots faster than there predecessors. They also have enclosed wheelhouses for greater protection against the elements, as well as upper steering positions for better visibility. Each boat now carries a small inflatable boat to assist rescues in shallow water.

U.S. Coast Guard 47' Motor Lifeboat and 42' Special Purpose Craft - Near Shore Lifeboat

In 1986 the U.S. Coast Guard started a new project to replace the 44' Motor Lifeboat with a new 47' version. First a preliminary design was drawn up and after tests and considerable refinements, Textron Marine and Land Systems was awarded the contract to finish the design and build a prototype. This boat (CG 47200) was delivered in July 1990 for testing and evaluation, which lasted about 2 years. Many improvements were incorporated into the pre-production models, of which a further 5 were built between April 1992 and December 1994, for testing and evaluation at units around the coast. After further improvements to the design, a contract was awarded to Texton Marine and Land Systems to build 20, 47' Motor Lifeboats, the total number now to be built is 117. On the 13th of May 1997 the first production boat (CG 47206) was delivered to the National Motor Lifeboat School.

The last 44 to serve in the US Coast Guard, was the 44301 which was retained at Station Chatham in Massachusetts due to the special bar conditions there. She was eventually replaced by the 42001, 42002 and 42003 Special Purpose Near Shore Lifeboats which were especially designed for the station. The 44301 was decommissioned on the 8th May 2009 after 46 years hard work.
