A fascinating video of dolphins and whales creating and then playing with bubble rings — toroidal vortices, also known as vortex rings. (Also a bit of volcanoes blowing smoke rings.)
This May will be the 250th anniversary of the launching of HMS Victory, the 104-gun first-rate Royal Navy ship of the line best known as Lord Nelson’s flagship at the Battle of Trafalgar in 1805. HMS Victory was also Keppel’s flagship at Ushant in 1778, Howe’s flagship at Cape Spartel in 1782 and Jervis’s flagship at Cape St Vincent in 1797. Since 1922, the ship has been in No. 2 dock at Portsmouth, UK. Four years ago, a maintenance report concluded that the historic ship was riddled with rot and being pulled apart by its own weight. Since then, the problems have persisted.
This week, the BBC reported that HMS Victory is ‘slowly rotting away from the inside’. Continue reading

Redbird Reef lies sixteen miles out in the Atlantic Ocean from the Indian River inlet, near the ominously named Slaughter Beach, Delaware. One of three explanations for the town’s name is that the first postmaster was William Slaughter. Likewise, while many reefs are named after ships that ran up on them, that is not the case with Redbird, which is an artificial reef in around 80 feet of water. The reef is named after the 714 New York City Redbird subway cars that, starting in 2001, were dumped on the generally barren sandy bottom. The cars became home to sponges, blue mussels, sea grasses, as well as flounder, tautog, and black sea bass. The cars were built of steel and painted red, earning their nickname, Redbird. Before dumping, the cars were cleaned of oil and grease and the doors and windows are removed.

The ferry MV Kalaka is making its last voyage today, a short trip to the scrap yard. The 276′ ferry carried millions of cars in the Puget Sound between Seattle and Bremerton between 1935 and 1967 and was notable for her streamlined form, art deco styling and luxurious amenities. After more than thirty years of service, she was decommissioned and towed to Alaska to be used as a crab and fish processor at Dutch Harbor and Kodiak. She was returned to the Seattle area in 1998 but despite the efforts of various owners with a range of restoration plans, the ship became a derelict. MV Kalaka will be towed roughly a mile from a dock on the Hylebos Waterway, where she has been moored for a decade, to a graving dock on the Blair Waterway, where she will be scrapped.
New York harbor has lost part of its living history with the passing of Sal Polisi, longtime volunteer and master carver at the South Street Seaport Museum. For three decades, Polisi carved everything from figureheads to wooden signs, using the time honored methods of a master craftsman. All his work was done by hand, without power tools or computers. Beyond his remarkable skills, he also a friendly face at the museum and was well loved by all who knew him. He will be sorely missed.
From South Street Seaport president, Captain Jonathan Boulware:
It is with a heavy heart that we mark the passing of our own Sal Polisi, master woodcarver, Seaport stalwart for well over thirty years, and gentleman of few peers.
Edge’s Windmill, 1815 — Sim’s Wind turbine 2015
Recently, the NY Times and others have been reporting on the installation of the first commercial wind turbine in New York City. The Sims Municipal Recycling facility in Sunset Park on the Brooklyn waterfront has installed a 100 KW 160′ tall wind turbine. Wind power is expected to provide about 4% of the electricity for the recycling plant, while solar panels on the facility roof already provide approximately 16% of the plant’s electrical needs.
While the new Sims’ turbine is the first in New York City, it is certainly not the first in the harbor. Just across the water, an even larger wind turbine has been in operation on the Bayonne waterfront for the last three years. The Bayonne Municipal Utilities Authority’s wind turbine has a rated capacity of 1.5 MW and stands 262′ tall.
Wind power, however, has at least a two hundred year history in New York harbor. Continue reading
Rokudenashiko in her vagina boat
Last May, Japanese artist Megumi Igarashi posted on her blog, Maybe you were thinking, “Hey, what happened to that vagina boat?” Well, good news: The vagina boat finally set sail. (Honestly, the question hadn’t crossed my mind.)
Igarashi, who goes by the nickname Rokudenashiko (“the good for nothing girl”), had raised money through crowd-sourcing to fabricate a 3D printed plastic model of her vagina to be installed on a roto-mold kayak. From the photos, my only issue with the kayak is that there is no place to put on a spray skirt. The Japanese authorities had other concerns.
The Norwegian firm Lade AS is developing a hybrid ship design, Vindskip, in which the ship sails using lift off its airfoil shaped hull. It is an intriguing design. Nevertheless, I can’t quite figure out how it would work in practice. It appears that since the hull itself is acting as the “sail” the only way to trim the “sail” for differing wind conditions is to change course in relation to the wind. Perhaps I am missing something.
USS Donald Cook
At 1 p.m. on Friday, the breaking news on the New York Post and the United Press Twitter feeds was that the Chinese had attacked US naval ships with missiles and that the “US Navy was engaged in active combat with Chinese vessels in the South China Sea.” The UPI Twitter feed also reported naval combat and also featured a photo of Pope Francis with the quote, “World War II has begun.” None of it was true. The Twitter feeds had been hacked. By now it should not be breaking news that one should never necessarily take anything in the Internet at face value.
That being said there is a very interesting story floating around the net about an incident last April in which the Arleigh Burke-class guided missile destroyer USS Donald Cook was “buzzed” by a Russian SU-24 fighter jet. The fighter made 12 “close-range, low-altitude” passes near the Cook while the ship was in international waters in the western Black Sea near Romania, Pentagon spokesman Col. Steve Warren told reporters. The fighter was observed to be unarmed. A second unarmed SU-24 fighter jet was also observed in the area.
. …………………………………. “Fat Leonard” Glen Francis
In October 2013, we posted that a US Navy purchasing scandal sounded like a bad novel. Bribes, prostitutes, and Lady Gaga tickets were allegedly handed out to US Navy officers by a Malaysian businessman in exchange for classified information and directing business toward the Singapore-based contractor, Glenn Defense Marine Asia (GDMA.) GMDA was accused of overcharging the Navy tens of millions of dollars for port services.
The drama is not over, but it is winding down. Leonard Glenn Francis, known is military circles as “Fat Leonard,” pleaded guilty to bribery and conspiracy charges in federal court Thursday. Francis, chief executive of GDMA, faces up to 25 years in prison and will forfeit $35 million to the US government, according to the plea agreement.
It doesn’t feel very much like summer right now, but at least we are on the far side of the winter solstice, so each day brings spring a bit closer. And this spring, the Oliver Hazard Perry, the first ocean-going full-rigged ship to be built in America in over a century will begin sailing. The OHPRI organization has announced summer camp programs on the new sailing school ship. From their press release:
Teens from around the country and the world will board in July and August for thrilling one- and two-week Education at Sea camps. The 200-foot Sailing School Vessel (SSV) Oliver Hazard Perry, hailing from Newport, R.I., has a 500-ton steel hull and a 130-foot tall rig with square sails on all three masts. She will have a captain, officers, a cook, an engineer and a dozen other professional crew members, but the balance of her crew will be none other than the students themselves – after all, she is a Sailing School Vessel.
We have followed the E-Ship 1 for the last four years. The ship is a Ro/Lo cargo ship owned by the world’s third-largest wind turbine manufacturer, Germany’s Enercon GmbH and is distinctive because it is fitted with four Flettner rotors. The rotors are vertical cylinders which spin and develop lift due to the Magnus effect as wind blows across them. So far, Enercon reports that they are observing roughly 25% fuel savings due to the rotor sails.
In December, the Finnish shipping line Bore installed a single rotor on the ro/ro M/V Estraden. The installation is an updated version of the Flettner rotor featuring advanced materials and a leading-edge control system designed and built by the Finnish marine engineering company Norsepower Oy Ltd. The ship will be undergoing testing of the new rotor sail auxiliary over the next several months.
The basic design of the Flettner rotor has been around for over 90 years. Flettner applied for his patent on the design in 1922. The Flettner rotor ship Buckau set sail in 1925, first crossing the North Sea and then the Atlantic.
Last Wednesday, Rob Konrad went fishing alone in his 36 foot Grady White boat. He left Deerfield Beach, FL and headed about nine miles out in the Atlantic Ocean. At about 1PM, with the boat trolling at about 5 knots on autopilot, Konrad fell overboard when struck by a wave while attempting to reel in a large fish. He was not wearing a flotation device and could only watch as his boat headed east toward the Bahamas. Remarkably, over the next 16 hours, Konrad swam the nine miles to shore, managing to crawl ashore on Palm Beach at 4:30 a.m. on Thursday. Konrad was taken to a local hospital, where he said he was treated for hypothermia and severe dehydration. He told his story at a press conference yesterday and appeared to be in good condition given his ordeal. Konrad was a professional football player from 1999–2004. The team he played for? The Miami Dolphins. Fortunately for all concerned, Konrad swims like one. Thanks to Irwin Bryan for contributing to this post.
The new generation of VLCC has arrived. The acronym usually refers to tankers, specifically, Very Large Crude Carriers, but in this case I am referring to Very Large Container Carriers. Perhaps they should be designated VLCS, for Very Large Container Ships. Mærsk now has 13 of their Triple E Class in service, each with a capacity of 18,340 TEU (Twenty-foot Equivalent Units.) Fora time they had the bragging rights as the world’s largest container ships. Indeed the Triple E website’s URL is http://www.worldslargestship.com/.
Now China Shipping Container Lines has built CSCL Globe which it claims is largest container ship with a capacity of 19,100 TEU. CSCL’s bragging rights won’t last much longer as Mediterranean Shipping Company’s MSC Oscar is going into service this month with an advertised capacity of 19,224 TEU.
Frank Jade was a passenger on the Royal Caribbean cruise ship Oasis of the Seas until Thursday morning when he said that a large wave knocked him off an open deck and into the sea, approximately eight miles from Cozumel, Mexico. Reportedly, no one saw him go overboard and no alarm was raised.
As if by magic, however, Jade was spotted by someone on a passing cruise ship, specifically the Disney Magic, which was on the same course as the Royal Caribbean ship. The Magic lowered a boat and picked up Jade. The ship docked at docked at Punta Langsota so Jade could be transferred to a private clinic for medical care. Frank Jade is said to be in stable condition without any serious injuries. Reportedly, no one on the Oasis of the Seas even realized that Jade was missing. Oasis of the Seas, with her near sister ship, Allure of the Seas, are the world’s largest crusie ships with a passenger capacity exceeding 6,000 and a crew of 2,400.
One week ago the car carrier Höegh Osaka was intentionally beached on Bramble Bank off the Solent in the UK after the ship developed an unexplained list. Last Wednesday, the ship floated free from the bank. It is still, however, floating with a severe list of roughly 50 degrees. Salvors plan on pumping out close to 3,000 of ballast water which should reduce the list. Once the ship is brought closer to upright it will be towed to Southhampton. The salvaeg operations have been delayed by high winds. Last night winds of over 70 knots caused the ship to drag at anchor approximately 100m. The ship is reported to be carrying 1,400 cars and 70 to 80 pieces of construction equipment. So far there have been no oil leaks or other pollution reported.
Having just gotten back from warmer climes, I am still adjusting to the temperatures around 20 degrees F, with wind chills in the teens here on the banks of the Hudson River. I have come across a new video from the Maine Windjammer Association. They introduce the video as follows: “Best way to take the chill off a cold winter’s day? Check out our brand new 1:30-minute video that’s filled with warmth and sunshine! Enjoy!” Personally, a cup of hot coffee and a thick wool sweater helps me fight the chill. Nevertheless, it is a fine video of fine sailing vessels.
As we posted in December, the Mayflower II, a replica of the ship which brought the Pilgrims across the Atlantic in 1620, is now undergoing a multi-year restoration in the Henry B. duPont Preservation Shipyard at Mystic Seaport in Connecticut. The Mayflower II was built at the Upham Shipyard in Brixham, UK and delivered in 1957.
A new replica of the Mayflower is now under construction in Harwich, Essex, England. They have are close to completing the farming of the keel. The charity, Harwich Mayflower Project, aims to raise £4m to complete the reconstruction by 2020, the 400th anniversary of the famous voyage. The charity, which has already helped train 300 young people in skills such as carpentry, hopes its training centre will act as a “legacy” of the ship build.
The Kalmar Nyckel Foundation is seeking recruits to train as volunteer crew for the replica ship Kalmar Nyckel. The original ship of that name served as Peter Minuit’s flagship for the 1638 expedition that founded the colony of New Sweden, establishing the first permanent European settlement in the Delaware Valley, Fort Christina, in present-day Wilmington, Delaware.

As we posted on Sunday, the passengers on the NorthLink ferry Hrossey, crossing Pentland Firth, off Scotland, saw a grim sight out the ferry windows — the bow of the cement carrier Cemfjord floating vertically in the water. The ship was loaded with 2,000 tonnes of cement and had sailed from Aalborg in Denmark bound for Runcorn in Cheshire. Eight crew, seven Poles and one Filipino, are missing and are presumed to have drowned when the ship sank.
There are now serious questions as to whether the ship should ever have been allowed to sail. The Cemford sailed with several serious mechanical deficiencies. There was a serious problem with her bilge pumps. Though managed by the German company, Brise of Hamburg, the ship was registered is Cyprus. The Cypriot authorities required the ship to carry two portable pumps on board the ship, presumably to supplement the ship’s bilge pumps, and limited the ship’s operation to 150 miles from the coast. The ship also had a faulty lifeboat davit, so an additional life raft was required to be carried. One life raft was spotted after the ship sank, but no one was aboard.
