“Irish builder Safehaven Marine has handed over a new coastal patrol and search and rescue (SAR) craft to Future Defense USA.”
Baird Maritime has a review of a new 45 foot self-righting patrol and SAR boat.
It is reportedly considerably faster than the USCG 47 foot motor lifeboat, has a longer range and an active stabilization system. I does not seem to have the space for survivors the 47 foot MLB provides nor the step-down cut the side of the hull that facilitates pulling survivors out the water. It does have a platform at the stern.
You can see the builder’s story about this boat, including a video, here.
“An integral transom platform and dive ladder allows for dive operations from a spacious aft deck.”
Just wanted to pass along this video of new pilot boats for Los Angeles found on MarineLog. Requirements for pilot boats can be similar to those for motor lifeboats. As the 52 footers are reaching the ends of their very long lives, with one taken out of service already, these might be worth a look. In some places a motor lifeboat larger than 44, might effectively replace 87 foot Marine Protector class patrol boats as well. Specs are here.
The designer of these boats, Carmarc, in the UK, also designed a larger, self-righting 29 knot 75’6″ pilot boat that was built by Kvichak Marine Industries, Seattle, WA, now Vigor, Ballard, for the Columbia River Bar Pilots. Kvichak Marine was the developer of the Response Boat, Medium, also a Carmarc design.
MARCH 19, 2014 — Seattle headquartered Kvichak Marine Industries has delivered Astoria, a self-righting 75 ft 6 in all-aluminum pilot boat, to the Columbia River Bar Pilots (CRBP) of Astoria, OR.
gCaptain had a report on this new hull form, which a University of Iceland study found reduced slamming as much as 95% compared to a deep-v hull. It explains the development of the hull, I needed more information to understand how it worked.
The company website has many much clearer photographs as well as the video above.
Claimed advantages are:
- Exceptionally smooth and comfortable due to limited slam on waves.
- Significantly reduced slamming results in less mechanical and equipment fatigue, extending the lifetime of expensive electronic equipment on board.
- Greater on-board safety from significantly reduced slamming means reduced risk of injury, lower crew & passenger fatigue and related costs
- Precision performance without compromising cruising or top speed.
- Immediate handling response with no sliding
- No wake created behind vessel, resulting in less water disturbance
- Exceptional stability and balance when idle and at speed
- High payload capacity without compromising cruising or top speed
Could this concept be scaled up for a Motor Surf Boat? Apparently the Icelandic Association for Search and Rescue is already looking into the possibility of a 15 meter (49 foot) MLB.
Thanks to Lee for bringing this to my attention
I did do a post on this new class of motor lifeboat before, there is more detail there as well as a comparison with the 47 footer, but thought you might like this video.

McIntyre Bay and Pachena Bay loaded on the Atlantic Raven
The Canadian Coast Guard is getting some new assets. They are getting two new 62 foot Motor Lifeboats that will be stationed at Port Hardy BC, on the NE tip of Vancouver Island, and Bella Coola, about half way up the British Columbia coast.
They are being transported on the newly leased Atlantic Raven, seen above, which will join its sister, the Atlantic Eagle. They will serve as Emergency towing vessels.
The two larger vessels are expected to be homeported in British Columbia. The Atlantic Eagle in Victoria and the Atlantic Raven in Prince Rupert near the border with SE Alaska
According to Naval Today,
One will patrol a northern area in Canadian waters between Alaska and the northern tip of Vancouver Island, and the other a southern area including the west side of Vancouver Island and the Strait of Juan de Fuca. They will also be available to conduct search and rescue operations and support environmental responses, when required.
Canada has dispatched a RCAF C-146 search and rescue helicopter to assist local authorities in dealing with the fires in California.
Thanks to Ken for bringing these two developments to my attention
Late note: CCGS Corporal McLaren, a 140 foot cutter similar to the Webber class, slid from it cradle into the water at Sambro, Nova Scotia shipyard. The stern is under water. Vandalism is suspected.
Thanks to Walter Y. for bringing this to my attention.
Canada is building twelve large, relatively fast, self-righting Motor Lifeboats. These are the “Bay” class and the first are now making an appearance.
Reportedly they will be “capable of safe operation in extreme weather up to Beaufort Force 12 conditions and are able to survive in 12 meter (40 foot) seas.”
This again brings to mind the fact that at some point we will need to replace the four 52 foot MLBs and we may also want to use the replacement class in other areas where exceptional seakeeping and longer range than the 47 footers is desirable. We did discuss this possibility earlier including some other alternatives and got lots of comments.
Chantier Naval Forillon and Hike Metal were awarded contracts totaling $89.2 million (Candian presumably, about $67.5M USD–Chuck} to build twelve of the new SAR lifeboats.
These self-righting, 20-meter (65.6 ft–Chuck) boats are powered by a pair of MTU 1600 HP marine Diesel engines providing a speed of up to 24 knots in extreme weather conditions. These vessels are primarily a day boat and will be operated by a crew of up to five Coast Guard seamen.
The vessel’s particulars are as follows:
- Length overall: 19.0 metres
- Length DWL: 17.5 metres
- Beam, moulded: 6.3 metres
- Depth, moulded, at midship: 2.58 metres
- Hull draft, nominal: 1.67 metres
- Power: 2,400 kW
- Speed: 23.5 kts

Third Round of Industry Input Sought On 47-Foot Motor Lifeboat Service Life Extension Program
July 13, 2018
A request for information (RFI) was released by the Coast Guard on July 12 for the 47-foot motor lifeboat (MLB) service life extension program (SLEP) as part of the In-Service Vessel Sustainment (ISVS) program. The Coast Guard is providing industry with the latest draft of the statement of work and specification along with access to the majority of the MLB technical data – drawings and technical publications – while seeking industry comments before making a formal solicitation for the contract, which has an estimated value of over $100 million.
This is the third RFI for the MLB; the first was released in September 2016 and the second in November 2017.
The MLB is the Coast Guard’s primary search and rescue platform in surf and heavy weather conditions. The fleet of more than 100 MLBs is approaching the end of its planned 25-year service life, and operational availability has been limited by parts availability and obsolescence issues. The SLEP will extend the useful life of the MLB by 20 years. The original operational capabilities and characteristics of the MLB will effectively remain the same, while efforts to enhance human system integration will be made where practical.
“This RFI answers questions posed through prior industry engagement,” said Cmdr. David Obermeier, deputy program manager for boats acquisitions. “It also gives industry the opportunity to provide additional feedback on the latest draft statement of work and specification.”
The RFI can be found here. The deadline to submit responses is July 27, 2018, at 2 p.m. EST.
