COLREGS - The final word on pecking order in restricted visibility.
Sorry Jeff,
It seems I also missed much of the earlier thread. I was agreeing with the point that thick fog is not the only type of restricted visibility. Now that I have discovered a bit more about the original thread, I should perhaps add a couple of points; First Point: Rule 19 Very definitely applies to all vessels at sea by virtue of Rule 1 (Application) '(a) These Rules shall apply to all vessels upon the high seas and in all waters connected therewith navigable by seagoing vessels' Second Point: Did Neal really claim that you don't get wind in fog? He perhaps needs to understand the process by which sea-fog is formed. It happens when warm, wet air comes into contact with a sea that is colder than it's own dew point. The only way sea fog disperses is 'normally' with a change in wind direction which brings in dry air which is able to absorb the moisture in the fog. Continued wind from the same direction merely feeds more moisture, and thus, more fog! If the same wind direction continues for long enough - the fog gets thicker and thicker. I have certainly been in situations where I have been sailing in thick fog. I find it safer than motoring because you can hear other vessels sound signals much easier than with an engine on. Sorry to bore everyone with this pedantry, but I lecture in both COLREGS and Meteorology amongst other things. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Bill Wife and I rather enjoyed the day. Anchored up by Angel Island, to avoid the mess by Alcatraz, then went to Ayala Cove on Angel Island after the show and got a slip and did a little hiking.

COLREGS - The final word on pecking order in restricted visibility.
Extremely thick fog is mostly a myth. Yes, it occurs on
occassion but the general run of the mill fog is not so thick that vessels can collide without ever seeing one another. At any rate, the worst case scenario of pea soup thick fog is but one case of restricted visibility and the majority of the other cases definitely allow in-sight situations in or near an area of restricted visibility. In sight situations are ruled by the in sight rules which specify give-way and stand-on status for vessels in sight of one another. Jeff, Otnmbrd, Shen44 and Rick have up till now maintained there is NEVER a stand-on vessel in or near an area of restricted visibility while I have maintained there IS a stand-on and give-way vessel in or near an area of restricted visibility. I'm right and they're wrong - that's the bottom line. I maintain that my sailboat even in a thick fog is going at a safe speed by virtue of the fact that the hull speed is less than seven knots max. Many fogs have little or no wind so I may well be going even slower. Even if the winds are brisk in a fog and I'm going hull speed I'm still going at a safe speed. In effect, I'm standing on and I'm doing it completely legally. If I hear the fog signal of a motor vessel I know right away if and when we come in sight of each other I am the stand-on vessel and the motor vessel is the give way vessel unless I'm overtaking the motor vessel which is not likely at all considering they all think safe speed is 10-15 knots instead of the usual 20-30 knots - let's face the facts here for once. Therefore, I keep going at my safe speed of five or six knots and try to determine by the sound signal if there's a danger of collision. If I determine there is a danger of collision I change course - I'm certainly not going to take all sails down and come to a stop and become a sitting duck to be run over and sunk by a ship not keeping an adequate lookout and going too fast for the conditions. This would be causing a collision and not avoiding a collision - a violation of the RULES. Yet this what the arrogant tugboat captains are saying the Rules require me to do. WRONG! When a motor vessel hears the fog signal of a sailboat or any other boat above it in the pecking order it knows before even coming in sight of that vessel that the motor vessel is the give way vessel in a close quarters situation and a close quarters situation in most cases of restricted visibility in an in sight situation. This is what I call the abbreviated pecking order. That there is an abbreviated pecking order proves there is a give-way and stand-on vessel in restricted visibility. If and when the motor vessel and sailing vessels come within sight of one another the motor vessel already knows it is the give-way vessel in all but the overtaking situation. (we're not talking narrow channels, traffic schemes, etc, here - we're talking at sea.) This means the give-way/stand-on status exists in or near an area of restricted visibility.

I guess in pieman land you get light fog only. Here in North Calif you get
friggin fog so thick you can not see the front of the car from the drivers seat! Bill "Simple Simon" wrote in message ... Extremely thick fog is mostly a myth.

COLREGS - The final word on pecking order in restricted visibility.
Yes they are both different, but they are equally hazardous to shipping and
should be treated accordingly. I suppose you are implying that there is no wind when you are dealing with land fog? What do you think causes the land fog to move out to sea? The Wind. Drainage winds and katabatic winds can both move off land out to sea and carry fog with them. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I don't think fog is moved around much by the wind. Fog develops when atmospheric conditions are such that the air becomes saturated with water vapor. A distant fog bank on the ocean doesn't "blow" in to surround your boat. The fog that surrounds you generates at your location as the atmospheric variables permit. Eisboch |

You've never obviously seen it blowing in the Golden Gate on
its way to Bezerkeley. The interior valley heats up and rises, and the air flows from the cooler ocean toward the valley. It is typical to see fog moving at 30+ kts through the slot between Angel Island and Alcatraz. "Eisboch" wrote in message ... "Tim Roberts" wrote in message ...
