Depends. But since this is the South Tower of the Golden Gate bridge and
Baker Beach, the ocean will make it into very small pieces. They probably read the chart and saw the South Channel designation and used it. There is no South Channel and not for a lot of years. You can get through if lucky and a calm day. They should of gone through the middle of the gate, using the commercial ship channel. Still can get rough but lots more water underneath and the waves do not break normally. And lately the seas have been big swells. 10'-15'ers. Bill "Pierre" wrote in message . ..

I'm surprised the charts still indicate a channel if there isn't one. I was
also surprised at how the person in the boat (can't seen person #2) was sailing into a nasty situation and not even looking around. Certainly the beach and rocks, along with the very high possibility of shoal water, was evident right in front of them? And to just sit there and not even be concerned?

If you sail very near the rocks it is deep enough most of the time. It is
actually about 5 Fathom on the charts. NOAA chart 18645 I actually use Waterproof Chart #84 which is the reproduction of the NOAA chart. There is deep water on both sides of the South Tower but the swell comes in on that side. The surfers at Fort Point (under the south side of the bridge) are there most of the time. The problem at the gate is the 2 banks outside the channel. the North one is the Fourfathom bank and we crab there on nice days in about 70-90 feet of water. On bad days we do not go out. As the swell can be breaking on the bank. "Brian D" wrote in message ... I'm surprised the charts still indicate a channel if there isn't one.

Why is there breakers and big waves if the water is 4 to 5 fathoms deep? Normally, breakers from normal (or even large) swells don't roll over until the water is closer to 20' deep or so. The way the water was rushing out in front of the breaker in the sequence of photos, it looked very shallow. Any clue why this is happening in that spot? Brian "Calif Bill" wrote in message nk.net...

They are probably 14-20' swells and there is a big bar outside the
"channel". That area has ate a lot of ships over the years. Under the middle of the Gate it is deep. 33+ fathoms. But on both sides of the channel there are big bars. The slowing water from the bay carrying silt drops it. The North bar is easier to watch from the Marin Headlands and when big seas are happening, it is great to go out and watch the breakers on the bar. And the average depth of the bar is 4-5 fathoms.

Me either, I have looked at the colors trying to find the right counter
current but that was under the middle of the bridge. Once in I would play the normal game of close to the St. Francis when the current was foul but it never crossed my mind to not be in the ship channel coming under the GG. And that was on a CT-41. On the other hand, I love sailing those Santanna 22's and was surprised that it didnt surf. It might have been the skipper but why would anyone sail where people are surfing?

Being a Gulf of Mexico sailor, this entire sequence of pictures puzzled
me ( I saw 113 pics in the sequence). Was this an isolated wave or was the camera angle so odd that it didnt capture other waves? After the initial capsize, it looked as if if maybe there was another wave and then NO MORE. Huh? Was this a tidal bore coming into the bay so it produced one or two isolated waves? In the entire sequence of pics, there were no more waves of any size at all. What was this? |
After looking at many wave photos on this page, I think wave behavior
in that location is different than I am used to. This place seems to have a very long period between waves with nearly flat water between them, weird. |

You have to remember the waves hitting here have a couple of thousand miles of open ocean to build in. Keep in mind these are not traditional breakers, rolling into a beach, but swells coming through a narrow channel - not very shallow water, but still a bar with suddenly shallower depths. For more info: http://www.surfline.com/travel/surfm...fort_point.cfm It appears the tide was coming in, so the boat was caught in one breaker - rolled and dismasted - continued drifting under the bridge where the wash of a second wave rolled it again, and then into the relatively calm water of the bay. |
And swells coming in through a narrow channel accelerate through the constriction. Some won't have been large enough to break, while others will be. I think that might be why there's a long period between rollers in the picture sequence (of an obviously dangerous place, else why was someone rushing to get the camera out BEFORE anything bad happened?). Also, ships moving through the channel disrupt the swells, or create their own too. Brian D "Sal's Dad" wrote in message ...

The only chart I found online is at
http://historicals.ncd.noaa.gov/historicals/histmap.asp ; go to "Entrance to San Francisco Bay" 1974 # 5532 - download 5532_1-1974 and zoom in. Zooming in on the southern end of the bridge, you can see that between Fort Point and the South Tower it shoals - from 200-300' in the main channel, to 30' or so where the capsize occurred. The shipping channel under the main span stays 200-300'. Once past the bridge, the harbor widens immediately; presumably the first pier is the one seen in the later photos.

You have to remember the waves hitting here have a couple of thousand miles of open ocean to build in. Keep in mind these are not traditional breakers, rolling into a beach, but swells coming through a narrow channel - not very shallow water, but still a bar with suddenly shallower depths. For more info: http://www.surfline.com/travel/surfm...fort_point.cfm It appears the tide was coming in, so the boat was caught in one breaker - rolled and dismasted - continued drifting under the bridge where the wash of a second wave rolled it again, and then into the relatively calm water of the bay. |
