Law of Gross Tonnage
The law, which is more common sense then explicitly written in the code, goes like this: “The heavier vessel always has the right-of-way.”
This is based on simple Newtonian physics. Newton’s first law talks about objects in motion stay in motion unless another force is acted upon it. In other words, if a boat is moving a 5 mph east and you were in the vacuum of space, it would never stop traveling east at 5 mph. However, we all know when we stop our engine on our boat, we slow down.
How long it takes to go from 5 mph to zero, depends on wind, and current. Even if there was no wind or current, we’d still slow down, because the water itself provides friction upon the hull of the boat, and that in itself acts as a brake.
We all have, by observation found that the bigger the object, the longer it takes to slow down. Newton’s second law of physics talks about how the amount of force required to move an object is inversely proportional to the mass of the object.
So, if a tug and barge were traveling down a narrow channel, and you stopped your boat 1,000 feet away, right in front of the tug and barge; and, if the master of the tug saw you immediately; and if the master of the tug immediately began to stop the tug and barge; you’d have less than one minute to move your vessel.
Because if you didn’t move your vessel in less than 60 small seconds, the tug and barge would just run right over you. It would be impossible for the master of the tug to stop, based of the collective mass of both the vessel and the barge, in 1,000 feet.
The law of gross tonnage is un-relenting. It is a fact of life. What also is a fact of life, is that you should not depend on the master of the tug or any other large vessel is able to see you, either visually or on radar.
A U.S. Navy guided missile destroyer was left with a gaping hole on one side after it collided with an oil tanker early Sunday just outside the strategic Strait of Hormuz.
The collision left a breach about 10 feet by 10 feet (three by three meters) in the starboard side of USS Porter. No one was injured on either vessel, the U.S. Navy said in a statement.
The collision with the Panamanian-flagged and Japanese-owned bulk oil tanker M/V Otowasan happened about 1 a.m. local time. Photos released by the Navy showed workers standing amid twisted metal and other debris hanging down from the hole.
The cause of the incident is under investigation, the Navy said, though the collision was not "combat related." There were no reports of spills or leakages from either the USS Porter or the Otowasan, the Navy said.
Navy spokesman Greg Raelson said the destroyer now is in port in Jebel Ali, Dubai. "We're just happy there were no injuries," he said. "An investigation is under way."
Looks like an end of career voyage for the for the commanding officer. I guess making the Strait safe against the Iranians isn't without it's own hazards. It's certainly not the first or last time something like this will happen.
If the Iranians have oil and we have cash money it's hard to understand why it requires our military when there's a mutually beneficial transaction to be had. Let's identify the most primary elements of the impasse.
