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.

You can also check out the original post from the Senate Committee on Commerce, Science, and Transportation. (Same video is available there, but the meeting does not actually start on that version of the video until minute 36.) There you can also find the written statements of the other three witness who constituted the second panel. The Commandant was the sole witness on the first panel.
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.
45m Western Pacific Fisheries Protection–They have not seen much risk of Illegal, Unregulated, or Unreported fishing.
51m Inland River Tenders
56m We may need to replace the 52 ft MLBs with something larger than the 47 foot MLB sometime in the future, but their end of life is not yet apparent
58m Coast Guard Museum in New London
60m Sexual Assault in the CG
1h02m Puerto Rico/Virgin Islands continuing commitment and its effects on drug seizures and alien migrant interdiction.
1h05m Vessel homeporting
1h08 CG center of expertise, particularly in regard to clean up spills in ice and fresh water
Motorboat & Yachting (via gCaptain) brings us a video test of a unique craft designed for military operations. As you can see, it is pretty seaworthy. Its shape and composite building material make it stealthy. It has a disappearing remote weapon station.
Beside, It’s always fun watching guys go weightless, followed by high-G.
