Race Three

Sure there was a race last Saturday, and there are results to report, but let’s skip straight to the good stuff: the most spectacular collision I’ve ever seen.

Bear in mind, I’ve seen more than a couple in the last couple of years (and, in fact, been involved in a few of them). Even Tom Hirsh, the guy who owns the boats we race and who has publicly proclaimed something close to a you-bang-em-you-buy-em policy, mentioned privately just last week that “if you don’t crash now and again you’re just not trying hard enough.” But this was a doozy.

A cutter called the Californian, the official “tall ship” of the state of California and a beast of some 130 tons, often cruises San Diego Bay. This particular day, it was out and about along with another sailing ship — name and exact size, I regret to say, unknown, but it was nearly as large, and let’s call it the Phantom. The two were scheduled to go out and blast cannons (plenty of gunpowder, no actual balls) at each other the next day, and they were, I suppose, warming up.

And there we were — “we” being myself and Midshipman Krabby Kyle — close-hauled on the final leg of our race, battling it out with archrival Steve McNally for first. We were on port tack, and I could see that the Phantom was on collision course on starboard. He had, in other words, right of way. But you know what? That didn’t matter. The law of gross tonnage applied here, and I was going to get out of his way. We tacked, and it cost us, and we were annoyed that we had to tack, but all was well.

Now, the Chapman brothers were in our race. As it happens, I am the only person to have entered a boat in these races longer and more regularly than they have. They’re established. But they have a record — a “crash-to-takeoff ratio,” as Tom put it in that private conversation, far exceeding that of any other entrant. They’re also remarkably uneven sailors; sometimes they’re way back in the fleet, and sometimes they contend for first. This was one of the latter occasions. They’d led much of the race and, only in a late leg, had fallen into a close third.

So, a minute or two after we were clear of the Phantom, I heard a noise. I looked back. There were the Chapmans, in exactly the same situation in which I had found myself a few minutes before, except apparently they’d never heard of the law of gross tonnage. (Admittedly, it’s a concept that’s essentially intuitive; I doubt it appears in any rule book.) They were crossing before the Phantom, on port to its starboard (as if that mattered!), and they had already made contact — hence the noise. The Chapman’s mast and the ship’s bowsprit had fouled, and I watched their mast being literally ripped right off their boat.

Hoochie Mamma! But, amazingly, there was no hull-to-hull contact, and no one was hurt. Even so, I turned back to offer any help we could (a decision that seemed obvious to me). It took less than a minute to reach them and to have them convince us they were ok and wave us back into the race, but by then we had no chance of catching Steve. (And in fairness to Steve, we likely would not have caught him anyway.) But the turning back led us to be caught by another boat, and we ended up in third.

So, in the final race a week from this Saturday, it seems highly unlikely that I’ll catch Steve (I’d need to beat him by four boats), and even less likely that the third-place boat will catch me. So it looks like it will be a nice, leisurely affair resulting in a second overall. Providing, of course, that I don’t run into anything……

There is nothing like a good sailing story involving a crash. Say, isn't a port tack boat always required to keep clear of a starboard tack boat?

The Law of Gross Tonnage is an accepted nautical convention that when a sea-going vessel has the right-of-way as established by the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS), it should nonetheless give way when faced with a larger vessel. This law is regularly invoked in non-maritime situations, such as when a bicyclist with the right-of-way invokes the Law of Gross Tonnage to avoid the Sport Utility Vehicle (SUV) that is about to cut them off.

The heavier vessel always has the right-of-way. There is no explicit directive in maritime regulations or law for the the Law of Gross Tonnage other than it is common sense that giving way and being alive is usually better than forcing one's right-of-way and being dead.

Example:

Two ships sailing in a battle group are operating off the coast of Southern California near San Clemente Island in the Southern California Operations Area. First, Oliver Hazard Perry class Guided Missile Frigate USS RENTZ (FFG-46) weighing a svelte 4,100 tons is going 20 knots at heading 090 (due east). Second, conventionally powered Forrestal class Aircraft Carrier USS RANGER (CV-61; aka "Danger Ranger") weighing in at a pudgy 81,000 tons is sailing at 22 knots, heading 180 (due south). The two vessels are approaching on collision headings.

COLREGS Rule 15 states that "When two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way and shall, if the circumstances of the case admit, avoid crossing ahead of the other vessel."
This would indicate the RANGER should take action to avoid RENTZ. In fact, COLREGS Rule 17 requires that RENTZ maintain current course and speed so as to allow RANGER to maneuver appropriately out of danger of collision.

However, the Officer of the Deck (OOD - i.e., the guy in charge of directing the ship's maneuvers) on RENTZ has had many previous encounters with RANGER and invokes the Law of Gross Tonnage to immediately relinquish right-of-way and turns starboard to course 190. The COLREGS allow this when it is apparent that the "give-way" vessel is not maneuvering as required.

True Story: One day on the RENTZ we observed the crew of the RANGER practicing small arms fire (shotguns, .45 caliber handguns, etc.) off of the fantail, or back end, of the RANGER. The RENTZ OOD placed a call to the RANGER OOD resulting in this conversation:

RENTZ: Uh, RANGER, is your crew practicing small arms fire off of your fantail?
RANGER: Affirmative, RENTZ.
RENTZ: Uh, are you aware that we are 1000 yards astern of your fantail?
RANGER: That's an affirmative, RENTZ.
RENTZ: Could you stop shooting at us, please?

"Hmmm. Small arms fire of the stern. Not a bad idea . . . "

Commodore Linda said...

you'd be better off shooting from the bow! :-)

"Small arms fire? How about heavy artillery? I wonder how big a piece I can carry and still stay afloat? Hmmm . . . "
