Lava Bomb Hits Sightseeing Boat In Hawaii

5 Knots Everyone Should Know

BSR says...

Best description I've heard for a Bowlan knot was from a captain of a scallop boat out of Port Canaveral. He said "...it won't come loose and you can get it loose."

These revelations about Iran show Obama got played!

Nearly 2 years and still ZERO nothing with Trump/Russian collusion. Mueller's indictments of 13 so far are for low level irreverent to Trump or pre Trump issues

However boat loads if nefarious activity between HRC, DNC, CIA,FBI to interfere, monitor, railroad Trump.

"They" being Trump and his Russian buddies?
Hmmmm....we agree then....time to reevaluate my position.

Russians create an ice floe and ride it down the Don River!

Kurzgesagt - In a Nutshell: Egoistic Altruism

newtboy says...

There are a few problems they skipped.
First, that bigger pie is still finite, but we act as if it's infinite, pretending that one person having billions doesn't adversely effect others, but that's simply not true.
Second, it overlooked the fact that those countries going through industrial revolution often do so by using other non industrial countries resources, making it impossible to industrialize everywhere....we would need at least one more planet to harvest.
Third, it never pointed out that the GDP increases caused by industrial revolutions were met with massive increases in population, which decreases the per capita net worth significantly. Doubling GDP while tripling population makes the average person have less, not more.

I'm disappointed they didn't mention the French revolution, caused largely by the wealth disparity they're discussing.

This video seems to be a long winded version of 'a rising tide lifts all boats'.

To be fair, what I thought is new is the cheaper motor running on regular unleaded gas more efficiently. Airplane fuel is insanely expensive compared to gas, and harder to get in remote places.
Ground effects plane/boats have been around for quite some time, but not in a commercially useful configuration. This seems like a big step up from small ferries or tour boats (faster and smoother rides) and far cheaper than small planes to buy and operate.

Yeah, the biggest ecranoplan was enormous, with immense lifting capacity but little evasive capacity, so they were awful in practice as military vehicles except as transports well behind the front. I can't find any instances of them being used in conflicts.

Yep,

What once was old is new again! This tech has been around for decades.

Here is a Lun-class Ekranoplan on the Caspian Sea.

I can only guess those are nuke rated missiles it is firing.

The Moiré Effect Lights That Guide Ships Home

Hi Tom, I'm a merchant navy officer who used to work around there, although I never came across this particular light... Sector Lights and Leading lights (parallax) are the internationally recognised marine signals for this sort of use (white light centre, with red and green lights either side to guide you to a safe channel, which i'm sure you've researched and are aware of), but one thing that doesn't come up too often is lines to specifically avoid, and as such there isn't an internationally recognised means of transmitting this with lights. The signal is pointing towards the danger, which is unusual in maritime practice, but it's certainly not a common light and isn't in the IALA buoyage system used for identifying marine hazards.

If it's in a marina, which i think you mentioned, it'll be specifically to stop boats dropping anchor on the submerged cable within the marina's jurisdiction, and it'll be specifically referenced in the marina's or the solent by-laws as an anomalous regulation. (I don't have time to go and hunt it down, but it'll be there as a local reg.) As far as i'm aware, that's the only possible reason for it. It's an unusual solution to an unusual problem. I could of course be wrong...i bring no hard evidence to the table!
Hope it helps

Nauti-Craft Marine Suspension Technology

But... they mostly do that with helicopters.

When they use boats they drop a line and winch the crew up/down because the oil rigs are generally way too tall to go from deck to deck.

Also, I'm not entirely sure this technology is safer in rough seas than a traditional hull, especially when you factor in the added risk of mechanical failure.

Payback said:

Crew transfers to and from oil rigs in heavy seas. That's profitable enough to not require anything else.
