gCaptain is reporting:
A Dutch engineering firm has come up with a unique solution that it believes could be the answer to road and waterway traffic congestion caused by the raising or opening of low movable bridges so that tall vessels can pass below.
To solve this problem, Royal HaskoningDHV proposes that instead opening or raising the bridge itself, why not just use gravity to lower boats underneath?
The concept is actually fairly simple. The design uses a sort of floating lock that tilts back and forth, lowering and raising the water levels inside chambers beneath the bridge just like any other lock does.
Royal HaskoningDHV says that by using this ’tilting lock’, water levels can actually be adjusted by as much as 8 meters in the case of the Zeeland Bridge in the Netherlands and cost as little as $76 million, or approximately 60 million euros, to fabricate and install.

DAY 8, BORING IS GOOD
At 17:00 local time today, we are more than half way through Prince of Wales strait, at 72.26 N 118.48 W
Both Captains Rose and Grandy said on different occasions that ‘boring is
good’ when it comes to navigating in the arctic. Of course, boredom is
relative. There is nothing boring about being in command of a modern ship
in the arctic. Here, boring refers to not having to spend hours or days
beating through difficult ice. The easy life, relatively speaking.
The conditions have been almost ideal, good visibility under grey skies
still (a recurring theme on this voyage so far). Barely any serious ice to
speak of – serious at least for the Nunavik. Captain Rose is delighted with
the conditions – made to order really. The winds today pinched the 5/10th
concentration to the south side of the strait. The ship is slipping through
barely impeded, but for one small section. That small section however is a
reminder of the unpredictability of shipping in the arctic. One patch, even
a small one strategically placed, would make the route impassable by the
vast majority of ships.
Boring can be bad, however as it leads grown men towards silly endeavours.
Silly things like an Arctic Ice Bucket Challenge. So, while the ship very
briefly mired in a thick floe, the gauntlet was thrown – boys being boys, a
few took the challenge. Some, braver than others, stripped down to basics –
one brave soul went two rounds.
The water, drawn from the Arctic Ocean was invigorating to say the least.
Salt water freezes only at -1.8 degrees C, so the drenching was beyond
freezing as was the air temperature at minus 5. No ice cubes required here.
Forgotten in all the revelry, was the issuance of a challenge. So, to all
who dare, the challenge goes to other mariners (and hangers-on), in the
north and elsewhere.
PS – A corrector to yesterday’s entry – the NUNAVIK will be the second
commercial vessel through the strait. IN 1986 the Kalvik, a Canadian Flag
icebreaking anchor-handling tug plied these waters. She later became the
Arctic Kalvik in the Fednav fleet and sails still today as the Vladimir

As Britain’s most celebrated warship, she withstood the onslaught of the combined French and Spanish navies at the Battle of Trafalgar. But HMS Victory, the flagship of Lord Nelson, now faces its ultimate battle.
The 245-year-old ship is leaking, is riddled with rot and is gradually being pulled apart by its own weight, according to maintenance documents and a structural survey obtained by The Sunday Telegraph.

The Coast Guard is investigating a collision Tuesday between the Coast Guard Cutter Key Largo and the 42-foot commercial fishing vessel, Sea Shepherd, approximately nine nautical miles east northeast of Vieques, Puerto Rico.
At 6:38 a.m., the Coast Guard Cutter Key Largo was on a routine patrol when the collision occurred. Following the collision, the Sea Shepherd sank at a depth of over 100 feet.
The crew of the Key Largo recovered and embarked the two-man crew of the Sea Shepherd, Winston Ledee, 57, and Kenneth Turbe, 30, both residents of the U.S. Virgin Islands. No pollution or injuries have been reported concerning the incident.
The Key Largo is a 110-foot island class cutter homeported in San Juan, Puerto Rico.

Three Sheets NW is reporting:
“It’s like the Iditarod on a boat with a chance of drowning, being run down by a freighter, or eaten by a grizzly bear.”
That’s how the Race to Alaska’s webpage describes this new event.
“Like all good ideas,” joked co-organizer Jake Beattie when we spoke recently, “this one came over a beer.”

The Scuttlefish is reporting:
New York, far more typically known for its bright lights, big city vibe, has a new and quite unexpected tourist attraction. Sightings of endangered humpback whales (Megaptera novaeangliae) – more commonly seen off Alaska or the coast of Hawaii – have been on the rise in the waters around Manhattan and the Boroughs, and have more than doubled from two years ago.
The Big Apple’s best-kept secret won’t be a secret for long, with at least 52 humpback sightings this past summer. This increase in sightings may be due to an upswing in menhaden, one of their important prey fish.
