Here's another photo of the pilot boat, North Bend.
I mentioned before, that I was able to see by watching
online, that this pilot boat had moved away from it's dock and I knew this was in preparation to go off shore and put a local pilot on board a ship so that he could bring it in to dock at a chip loading facility.
I have watched this many times before, but learned something new this day. Something I had never witnessed.
It was foggy from the shoreline out to sea, but relatively sunny from the jetty into town........... not uncommon. Fog can persist directly on the coast all day, and not flow inland more than a mile or so. Foggy at the beach, yet sunny and blue skies everywhere else near by.
Looking at the Google map of the bay entrance, you can see the north and south jettys which stick out from the shoreline. They protrude less than 1/2 a mile into the ocean, and are made up of huge boulders. The two jetties block the large northern and southern waves and make entering the bay a much safer event and also help to control the amount of sand buildup and in the center of the shipping channel. The channel is dredged on a regular basis to keep sand buildup from making the water depth too shallow for the ships to come and go.
In the map, I drew where the pilot boat sat steady for an hour or so, till the ship finally came in,.
Usually, the pilot boat leaves the dock and then heads right on out, about 4 to 12 miles to put a pilot aboard a ship.......... but not this day....... it just
sat there mid way in the channel doing absolutely nothing. I was a bit confused.
Soon after I took this photo of the pilot boat, the fog rolled in along the shoreline and jetty where I was at. You couldn't see much....... maybe 50 feet out on the water. Minutes earlier, I could see the other jetty a half mile away.
We heard the ship's horn blast somewhere out there in the fog bank directly in front of us. I guess I missed this shot.
I raced a mile inward, and long the inner bay, the sun was shining brightly. The fog was only hovering on the coastline, not moving inland at all. The entire bay was sunny.
Long story short................. I say that a lot don't I?
I did a small vinyl repair today for one of the local retired ship pilots. I asked him why the pilot boat was just sitting there in the bay entrance for so darn long. I told him about how foggy it was.
He said that normally, the pilots use buoys, radar and other visual aids to navigate the ship in. He then told me that when it's foggy, the ship pilot will sometimes use the ships radar to lock on to the pilot boat, and simply follow the pilot boat in to the dock. He said that the pilot boat makes a lot better radar target than the bouys and other aids. Safety first, especially with a ship 660 feet long.
This is a tricky ocean entrance to navigate, partly because of sharp left hand turn that the ship has to make as it transitions from the ocean into the lower bay and also because of the narrow channel down through the bay.
The ships travel between the two jetties and around that first turn at nearly full speed. (10 to 12 knots) If they go slow, they wouldn't have very good control of the ship.......... the ships need to travel at a relatively fast speed so that wind and currents don't have as much effect on them.
.....anyway, that's my "Mr. Rodgers" show for today.
