Lifeboats have been modified by the addition of an
engine since 1890 which provides more power to get in and out of the swell area inside the surf. They can be launched from shore in any weather and perform rescues further out. Older lifeboats relied on sails and oars which are slower and dependent on wind conditions or manpower. Modern lifeboats generally have electronic devices such as
radios and
radar to help locate the party in distress and carry medical and food supplies for the survivors. The
Rigid Hulled Inflatable Boat (RHIB) is now seen as the best type of craft for in-shore rescues as they are less likely to be tipped over by the wind or breakers. Specially designed
jet rescue boats have also been used successfully. Unlike ordinary pleasure craft these small to medium-sized rescue craft often have a very low freeboard so that victims can be taken aboard without lifting. This means that the boats are designed to operate with water inside the boat hull and rely on flotation tanks rather than hull displacement to stay afloat and upright. Inflatables (IB)s fell out of general use after the introduction of RIBs during the 1970s. Conditions in New Zealand and other large surf zones was identified and Inflatable Rescue Boats (IRB), small non rigid powered boats, were introduced by New Zealand at
Piha Beach and have been put into use in many other countries including Australia and the RNLI in the UK.
Australasia In
Australasia surf lifesaving clubs operate
inflatable rescue boats (IRB) for in-shore rescues of swimmers and surfers. These boats are best typified by the rubber Zodiac and are powered by a 25-horsepower outboard motor. In the off season, these boats are used in competitive rescue racing. In addition to this, most states have a power craft rescue service. RWCs (Rescue Water Craft, Jetski) are common to many beaches, providing lifesaving service. The state of New South Wales operates dual hull fiberglass offshore boats, while Queensland, Tasmania and South Australia operate aluminum hull Jet Rescue Boats, of about 6m in length. Some regions such as North Queensland and the Northern Territory operate RNLI style rigid hull inflatables. In Auckland, New Zealand two 15-foot surf jet rescue boat powered by three stage Hamilton jet units were stationed in the 1970s and 1980s at Piha Beach the home of the
Piha Surf Life Saving Club.
Canada The
Canadian Coast Guard operates makes and models of motor lifeboats that are modified RNLI and USCG designs such as the
Arun and the
47 footer (respectively).
France The
SNSM operates over 500 boats crewed by more than 3200 volunteers, from all-weather lifeboats to jetskis, dispersed in 218 stations (including 15 in overseas territories). In 2009 the SNSM was responsible for about half of all sea rescue operations and saved 5,400 lives in 2816 call-outs and assisted 2140 boats in distress. The service has 41 all-weather rescue boats, 34 first-class rescue boats, 76 second-class lifeboats and 20 light rescue boats (and an amphibious rescue boat), and many inflatable boats. All these boats are made unsinkable by injection into the hull of very light materials (closed cell polyurethane foam) : with these buoyancy reserves, the boat itself full of water always remains in positive buoyancy; they also have a tight sealed compartment. All-weather lifeboats from 15 meters to 18 meters are self-righting. The first class lifeboat have capacities close to the all-weather rescue boats, the second class lifeboat are intended for slightly less difficult conditions. The first and second class boats, respectively 14 meters and 12 meters, which are the most recent boats, are self-righting. The boats are dispersed in 185 stations (including 15 in overseas territories). . This is the largest class of French lifeboat, at 18 metres long. The association owns 41 all-weather rescue boats, there are 30 of this type, the others being all-weather rescue boats of the 15.50 m class and the new generation all-weather rescue boats (CTT NG).
Germany of the
German Maritime Search and Rescue Service (DGzRS) In
Germany, the
German Maritime Search and Rescue Service (DGzRS) has provided naval rescue service since 1865. It is a civilian, non-profit organisation which relies entirely on individual funding (no government support) and has a variety of boats and ships, the biggest being the
Hermann Marwede with 400 tons displacement, the largest lifeboat in the world, operating from the island of
Helgoland. The DGzRS operates from 54 stations in the
North Sea and the
Baltic Sea. It has 20 rescue cruisers (usually
piggybacking a smaller rescue boat), mostly operated by own full-time personnel and 40 rescue boats operated by volunteers. Voluntary organisations such as the German Red Cross (
Wasserwacht) and
DLRG provide lifeguarding and emergency response for rivers, lakes, coasts and such like.
Netherlands The Dutch lifeboat association
Koninklijke Nederlandse Redding Maatschappij (KNRM) has developed jet-driven RIB lifeboats. This has resulted in 3 classes, the largest is the
Arie Visser class: length 18,80 m, twin jet, 2 x , max. speed , capacity 120 persons. Some local lifeguard organisations also respond on the SAR.
Scandinavia Most
Scandinavian countries also have volunteer lifeboat societies.
UK and Ireland Royal National Lifeboat Institution in
Poole Harbour,
Dorset,
England. This is the largest class of UK lifeboat, at 17 metres long. The
Royal National Lifeboat Institution (or RNLI) maintains lifeboats around the coasts of
Great Britain and
Ireland crewed largely by unpaid volunteers, most part-time, with equipment funded through voluntary donations. In Britain, the RNLI design and build several types of all-weather motor lifeboats, the
Arun class kept permanently afloat, the
Tyne class slipway-launched boat and the
Mersey class carriage-launched boat. More recently the Arun replacement
Trent and
Severn class prototype models were delivered in 1992 with the first production Trent arriving in 1994 and the Severn in 1996. The first production
Tamar class, replacement for the Tyne went into service in December 2005 and the
FCB2 class replacement for the Mersey is being developed for deployment sometime in 2013. The FCB2 class of lifeboat was on 11 April 2011 accepted as a proven design and given the class name
Shannon, continuing the RNLI tradition of naming all-weather lifeboat classes after rivers in the British Isles. Scarborough lifeboat station in North Yorkshire and Hoylake lifeboat station on the Wirral are two of the first stations to be allocated one of the new boats. Scarborough's Shannon class lifeboat will be named Frederick William Plaxton in his memory as he left a substantial legacy to the RNLI specifically to purchase Scarborough's next all-weather lifeboat.
Independent services There are at least 70 lifeboat services in Britain and Ireland that are independent of the RNLI, providing lifeboats and crews 24 hours a day all year round, consisting of unpaid volunteers. They operate inland, inshore or offshore, according to local needs.
United States The
United States Life Saving Service began using motorised lifeboats in 1899. Models derived from this hull design remained in use until 1987. Today in U.S. waters rescue-at-sea is part of the duties of the
United States Coast Guard. The
coast guard's MLBs, an integral part of the USCG's fleet, are built to withstand the most severe
conditions at sea. Designed to be
self-bailing,
self-righting and practically unsinkable, MLBs are used for surf rescue in heavy weather.
36' (foot), 1929–1987 The Type "T" model was introduced in 1929 with a two-ton lead keel, powered by a Sterling gas engine, giving a top speed of nine
knots (17 km/h). Minor updates followed in 1931 (Type "TR") and 1937 (Type "TRS"). From the early days of the 20th century the 36 MLB was the mainstay of coastal rescue operations for over 30 years until the 44 MLB was introduced in 1962. Built at the Coast Guard Yard in Curtis Bay, Maryland, 218 36 T, TR and TRS MLBs were built between 1929 and 1956. Based on a hull design from the 1880s, the 36 TRS and her predecessors remain the longest active hull design in the Coast Guard, serving the Coast Guard and the Life Saving Services for almost 100 years, the last one,
CG-36535, serving
Depoe Bay MLB Station in
Oregon until 1987.
52' (foot), 1935–1967; 1956–2021 In the mid-1930s the USCG ordered two 52-foot wooden-hulled motor lifeboats (MLBs) for service where there was a high traffic of merchants ships and heavy seas that had a high capacity in the number of person that could be rescued of approximately 100 and could tow ten fully loaded standard life boats used by most merchant vessels. Unlike the older 36-foot, the 52-foot MLBs had a diesel engine. The 52-foot wooden-hulled MLBs were the only Coast Guard vessels less than in length that were given names,
CG-52300 Invincible and
CG-52301 Triumph. Both were built at the
United States Coast Guard Yard;
Invincible was initially assigned to Station Sandy Hook, New Jersey, and
Triumph was assigned to Station Point Adams in Oregon. In time
Invincible was also transferred to the Pacific Northwest at Station Grays Harbor.
Triumph later capsized and sank during a rescue mission on January 12, 1961. s (2003) The Coast Guard introduced a steel-hulled successor, the
52-foot Motor Lifeboats, in 1956, and completed four steel 52' MLBs by 1961. These 52' MLBs also are known as "Special Purpose Craft – Heavy Weather" (SPC-HWX); maintaining precedent, these were named:
Victory (CG-52312),
Invincible II (CG-52313),
Triumph II (CG-52314), and
Intrepid (CG-52315). All four were stationed in the Pacific Northwest and remained active until 2021, when they were laid up as they had become too expensive to maintain. In December 2024, the Coast Guard released a request for proposal and environmental assessment report for a proposed replacement, the "Special Purpose Craft – Heavy Weather Second Generation" (SPC-HWX II) program. The preliminary design measures in overall length with a maximum beam of , capable of operating in seas of up to , breaking waves of , and winds up to .
44' (foot) During the 1960s the Coast Guard replaced the MLB with the newly designed boat. These steel-hulled boats were more capable and more complicated than the wooden lifeboats they replaced. In all 110 vessels would be built by the Coast Guard Yard in Curtis Bay between 1962 and 1972 with an additional 52 built by the
RNLI,
Canadian Coast Guard and others under licence from the USCG. The last active 44' MLB in the United States Coast Guard was retired in May 2009, however these boats are still in active service elsewhere around the globe. The 44' MLB can be found in many
third world countries and is faithfully serving the
Royal Volunteer Coastal Patrol in Australia and the Royal New Zealand Coastguard Federation. The current engine configuration is twin Detroit Diesel 6v53s that put out each at a max RPM of 2800.
30' (foot) surf rescue boat Another surf capable boat that the Coast Guard has used in recent years is the
30' surf rescue boat (SRB) introduced in 1983. The 30' SRB was self-righting and self bailing and designed with marked differences from the typical lifeboats used by the Coast Guard up until the early 1980s. The 30' SRB is not considered to be an MLB, but was generally used in a similar capacity. Designed to perform search and rescue in adverse weather the vessel is generally operated with a crew of two, a surfman and an engineer. The crew both stand on the coxswain flat, protected by the superstructure on the bow and stern. The boat's appearance has caused many to comment that it looks like a "Nike Tennis Shoe". Since 1997 the introduction of the faster 47' MLB and the phasing out of the 44' MLBs made the 30 footers obsolete. The class of vessels underwent an overhaul in the early nineties to extend their life until the newer and faster 47' motor lifeboats came into service, and in the late 1990s most of the 30 footers were de-commissioned. One still remains on active duty at Motor Lifeboat Station Depoe Bay in
Depoe Bay, Oregon and is used almost daily. This station was host to the last 36' motor lifeboat in the late 1980s.
47' (foot) The USCG has since designed and built new aluminum lifeboats and the first production boat was delivered to the USCG in 1997. The
47-Foot Motor Lifeboat is able to withstand impacts of three times the acceleration of gravity, can survive a complete roll-over and is self-righting in less than 10 seconds with all machinery and instruments remaining fully operational. The 47' MLB can travel at to reach her destination. There are 117 operational with a total of 200 scheduled to be delivered to the USCG. A further 27 models are being built by MetalCraft Marine under licence to the
Canadian Coast Guard.
Response Boat – Medium The
Response Boat – Medium is a replacement for the
41-foot Utility Boat, Large and the
USCG plans a fleet of 180 in the
USA.
