The Coast Guard is in the market for replacements for the 52 foot MLBs. Now this is, at 90 feet long, a good deal larger than the 64 foot maximum length replacement currently envisioned. At 120 tons, its larger than the 87 foot, 91 ton Marine Protector class WPBs, but in many ways, it’s probably more capable than either.
Compared to the 52 foot MLB’s planned replacement, it has longer range, probably higher sustained speed in adverse conditions, greater towing capacity, and a daughter boat capable of getting into the shallows. It also has a fire monitor and medical facilities.
Compared to the 87-footer, it appears more seaworthy. Though nominally slower than the Marine Protector class, it is probably capable of maintaining higher speed in rough conditions. It carries more fuel, 18,000 liters (4,755 gallons) vs 9464 liters (2,500 gallons), giving it a greater range at a higher speed, 900 nautical miles at 15 knots vs 882 at 10. Perhaps more impressive is the claim of a 600 nautical mile range at 24 knots. It also has bow thruster.
Something like this could replace both the 52-foot MLBs and at least some of the 87-foot WPBs. In addition to the Pacific NW, they would be a welcomed addition in Alaska or along the Maine coast.
The remarkable thing I see in the specs, is the crew, only four, about the same as the 52-footers. That would be a substantial savings relative to the ten-person crew of the WPBs.

Just got this comment from Peter on an earlier post,
All four 52 footers are officially retired today. They are all currently underway to rendezvous at Station Cape Disappointment. The Intrepid left Coos Bay yesterday, the Victory left Yaquina Bay at 0200 this morning and the Invincible will leave later today.
The end of a era.
This certainly was not unexpected, and we have had some indication the Coast Guard is looking for replacements. My Feb. 2021 post on the topic included a number of comments and referenced earlier posts and possible alternatives.
As seems to be too frequently the case, we have waited too long to look for a replacement for a system obviously approaching the end of its useful life. There should not have been a gap in providing a replacement. Additionally, in many locations, a faster more capable large MLB could also serve as a replacement for 87 foot WPBs–also approaching the end of their useful life. This could be a larger program than just five boats.

It looks like the Coast Guard may be finally looking at replacing the 52 foot Motor lifeboats.
“The U. S. Coast Guard (USCG) is conducting market research in preparation for the replacement of four Special Purpose Craft – Heavy Weather (SPC-HWX). The primary purpose of the SPC-HWX is to conduct Search and Rescue (SAR) missions in extreme weather conditions to include surf and extreme seas and be able to tow larger fishing vessels. Other missions will include Ports, Waterways, and Coastal Security (PWCS) and law enforcement. These boats will replace 52-foot SPC-HWX boats that were built in the 1950s and are increasingly difficult to maintain. The SPC-HWX boats will be deployed to four USCG stations in the Pacific Northwest. A preliminary table of requirements that outlines the features desired in a new SPC-HWX is attached…”
We could see this coming. One has already been taken out of service. They are approaching 60 years old, and, while they have warranted affection from those that have served on them, we can certainly do better. We have been discussing possible replacements for over seven years, here, here, here, here, and here
There are two specifications that I saw as unnecessarily limiting, first the dimensions, length, 64′, beam, 22′ max with fendering, draft 7′, and secondly the maximum speed, 25 knots. Are the maximum dimensions based on infrastructure limits, or are we unnecessarily limiting our choices? Limits on length in particular might preclude use of innovations like the Axe Bow. We really should not have to specify a maximum length, unless there are limits on supporting facilities. Competition will inevitably favor smaller craft as long as they can meet the other specifications. Higher speed is desirable and attainable, so why not add 30 knots as an objective speed and provide an incentive in the contract for reaching speeds over 25 knots. On the other hand the RFI include nothing about noise of G-force limits.
This RFI only refers to replacing the four 52 footers, but in many places, a larger, relatively fast motor lifeboat could be a suitable replacement for the 87 foot WPBs, after all you can expect heavy weather from time to time, anywhere the Coast Guard operates. If the Coast Guard does see the advantage of replacing WPBs with these larger MLBs, it is also possible to make this type of vessel ice-capable for operation in Alaska and and other Northern ports.
There should be no problem finding a builder with the appropriate experience. I expect Vigor now owner of the former Kvichak Marine Industries, Seattle, WA will be a bidder.
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.
“In the summer of 2020, Birdon America delivered the first of the upgraded 47 MLBs which was accepted by the U.S. Coast Guard. It had passed or exceeded all the U.S. Coast Guard requirements under the contract. Birdon will now proceed with the service life extension of over 100 of these vessels built between 1997 and 2003. Work on the first boat was completed at the All-American Marine yard in Bellingham, Wash. Other west coast boats will follow. The 47 MLBs on the east coast will be upgraded at an east coast yard beginning in 2022…a pair of US-built, 6-cylinder, Cummins QSC8.3-M engines were chosen for the repower as part of the MLB Service Life Extension Program (SLEP). These EPA3-rated engines have four valves per cylinder and produce 530 BHP each at 2,600 RPM. They replace the original 435-hp Detroit 6V92TA mains. The new engines exceed the contracted requirements in terms of noise reduction and fuel economy.”
Earlier, when I discussed developing a WPB replacement, I was primarily concerned that in addition to a SAR response, that the Coast Guard in major ports have a response to unconventional maritime attacks by terrorists or other hostile forces. But there are also a number of WPBs in small ports where such attacks would have far less impact and consequently are far less likely. The US shipbuilder Metal Shark has new 87 foot patrol boats in series production for Foreign Military Sales (FMS) that were evolved from the Marine Protector class. They might fulfill the needs of these smaller ports. They appear to be relatively cheap. Looks like the last group had a cost per boat of about $4.3M each. That is way less than the approx. $60M we are paying for the more capable FRCs. Still there might be a better alternative,
A recent Marine Log report that the EU is buying nine large motor lifeboats to help the Turkish Coast Guard deal with their immigrant crisis, got me to thinking that perhaps, at these small ports, what is really needed is a larger motor lifeboat. Specs for the Damen designed Turkish Coast Guard boats are here. They are apparently a version of the Netherlands own motor lifeboat.
Damen SAR 1906 motor surf boats
There has been a lot of work on development of Motor Surf Boats since the 47 footers and the now over 50 year old 52 footers. Canada and the Netherlands have both made such craft over 60 feet in length. The RAFNAR hull form looks particularly promising. They may not be more survivable than the ones we have now, but they may be better in other ways. Where we don’t need the long term endurance of a WPB, we could have a boat of about Marine Protector class size or perhaps some what smaller, that could operate with a smaller crew, be faster, tow equally large or larger vessels, reduce G-forces on the crew, and still be able to operate in weather where the legacy WPBs could not. There might also be Foreign Military Sales potential for such a vessel.
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.

This was something of a love fest for the Coast Guard with repeated praise for the people and actions of the Coast Guard.
This hearing was reputedly about how the Coast Guard had been impacted by the unusually severe Hurricane season. There is not a lot new here but there were some interesting remarks.
Polar Icebreaker Contracts
The intention is to Contract for the first Icebreaker and then employ block buy for the next two (28m). To me this seems to negate most of the advantage of a block buy. I don’t believe we will or should buy one and then wait until we have tried it out before contracting for the next two. That would necessitate a delay of at least five years during which we would still have the nightmare scenario of our only heavy icebreaker having no rescue if it should break down in the ice–certainly not an impossibility even with a new ship. If we are going to contract for the remaining two before testing the first, we might as well block buy all three.
First of class is always the most expensive. If the shipyard gets a block buy they know that initial improvements in productivity can be amortized over the entire block buy quantity. In some cases, in order to win the whole project, the shipyard will cut the price of the first ship substantially knowing they will make a profit over the entire project.
If we buy one and then block buy the second and third, we have paid for improvements to the winning yard with the first contract and minimized the chances for a competitive bid for numbers two and three.
Legislation has capped DOD participation in icebreaker procurement, so the bulk of icebreaker procurement costs will come out of the Coast Guard budget.
Authorization
There was a lot of discussion about the need to have the Coast Guard Authorization Bill signed into law, still not approved. You can see it here.
Other topics
There was a discussion of the high cost of the Coast Guard response to the recent series of Hurricanes.
Representative Sullivan spent a lot of time, discussing and advocating for an eleven mile road from King Cove (population estimate–989) to Cold Bay, Alaska (population estimate–122) which has an all-weather airport with two runways, one 10,180 feet and one 6285 feet in length. The Coast Guard connection is that the road would minimize or eliminate the necessity for the Coast Guard to Medivac emergencies from King Cove by helicopter, which is frequently hazardous. It is a Federal issue, because the road would run through a Federal reserve. The Commandant fully supported the desirability of completing the proposed single lane gravel road as a means of minimizing the requirement for helicopter medivac.
Video Breakdown
28m Domestic icebreakers–Design work on new domestic icebreakers is expected to start in 2030. That sounds a bit late to me. Mackinaw was commissioned in 2006 so if that is what he is really talking about, that makes sense, but the 140 foot icebreaking tugs are a different story. The first for of these will be 51 years old in 2030. More than half of them have already completed in-service which was expected to add 15 years to their service life. Morro Bay, at least, is expected to reach the end of her service life in 2030, and considering how long it takes us to build a ship we really need to start the process not later than 2025.
