Re: what was my mistake?

A tripping line is the best way, a line tied to the top (crown) of the anchor which enables you to pull it out backwards.
Having said that, whenever I've used one (when in a known likely area to snag) I've had more probllems caused by the tripping line than it's prevented.

Another way is to slide another loop of chain (with a line attached) down your anchor line in the hope that it will find it's way down to the crown of your anchor so that you can pull that out as per a tripping line.

Re: what was my mistake?

One other thing to consider -- if you keep a mask/snorkel/wetsuit on board, you can follow your chain down and (maybe) free it from the obstruction.

Basic snorkeling gear is also just great fun to keep on a boat. . . .

Re: what was my mistake?

Thanks everyone,

I just updated my navionics charts last week. I wasn't aware that Cheechako was using the term "wreck" for obstruction. I did check the charts before dropping the anchor. I saw nothing alarming on them.

I did most of my learning to sail in Monterey bay, and am new to the SF bay, and have 0 local knowledge or sailing friends in the area.

I actually had 2 anchors, and I still have the better of the two. I just need to buy some anchor chain now. I really should have tied a fender to it. I wasn't aware of how expensive anchor chain was... I was thinking $250. I had thought a diver would have cost more than the chain...

PM me--I might be able to help you out on the chain.

Re: what was my mistake?

You probably anchored in a cable area, see chart attached. Anchor snagged cable...

Re: what was my mistake?

Had that a couple of times. Once in Spain, no way to retrieve it, tried circling it, no luck. Fortunately a SCUBA class was nearby and the instructor dived it and freed it from being wrapped around, in his words 'the only rock in the bay'
Another time off Ibiza pulled the anchor up to move in the night but it would only come to 1m below the surface thanks to the pesky optic fibre cable from Ibiza to Majorca. No way we could pull it right up but we managed to get a line around the cable to take the tension while we lowered the anchor free. The cable was marked on the chart but about 150m out of position. I guess it had been snagged and dragged before....
No mistake in getting the anchor stuck but the above points are good to keep in mind
Mark the position on the plotter
Tie a fender/float and line to the chain
Use a anchor buoy tied to the head of the anchor in dodgy anchorages

Re: what was my mistake?

I heard of a diver who sells anchors that he recovers from Angel Island. Don't remember where I heard that story. I have anchored on the south east side of angel with no problems.

Re: what was my mistake?

Did you get GPS coordinates where you dropped the chain? Can you go back or take some divers back with you? I know lots of divers just love a challenge. I used to be one when younger.

kind regards,

Re: what was my mistake?

The east side of angel island looks nice. but there are cables, rocks, brick and "Stuff" in the water.

Better anchorage is paradise cove over by Tiburon. Nice clean mud. Ferry wakes can be fun, but more a problem during the week then weekend.

Aquatic park is calm, but busy with lots of swimmers in the water and lots of folks on land.

Clipper cove is very nice too. But only 5 feet at mlw (I measured last week with my 5 foot keel at 0.0 MLW) and thats 20 feet off the pier and 20 feet from the small boat dock at the end of the rock. Stay within that 20 feet. In the middle it's about 3 feet at mlw, avoid the middle, hug the pier. Back by the marina it's 14' at mlw. Really like clipper cover and much quieter with the new bridge.

Also china camp is an option on the west side of San pablo bay.

Richardson bay is not bad. Looks like there has been some cleanup there. A looks like only 100 boats in the middle right now. I anchor toward belvadeer, as it's a little quieter on that side of the bay.

There is also downtown petaluma with dockage ($24/day I think) but lots to see and do there. D street bridge needs at least 4 hours notice Half mile NW of the green marker in the petaluma river (there is only one) at entrance to a small creek on west side, is 3' at MLW from the middle of the river to west. Hug the east side if passing at under 3' of tide.

Re: what was my mistake?

I'm wondering just what kind of a Danforth was used, they made some not-so-good ploughs, but also the dual fluke kind like we have for our kedge, or stern anchor. While this instance is not one of dragging, in fact the fluke style Danforth is not a good choice where you get 5 and 6 knot currents running.

All the suggestions mentioned above are the canonical ways of trying to free a fouled anchor. We've used all of them at times. Mostly, they work. In all our years of cruising, have only left one anchor on the bottom. So now the OP has some good ideas.
Good on youse guys.

You have lots of friends right here.

Ask first, but also, I might have mentioned in one of your earlier posts:

Kimball Livingston's great book: Sailing The Bay.

Save some $$ over individual charts and buy a Maptech chart book of the area. Get your head out of eletronic only navigation. They used to make them with a DVD of MapSource sfotware, maybe not anymore, but even only the book will be a good thing to have, covers up to Bodega and east to Sacramento.

Yes, and you're in downtown at the Petaluma turning basin, immediately beyond the D Street Bridge, with lots of nearby restaurants, shops, and grocery. (You're likely need to motor up/down the Petaluma, if not the long and narrow dredged approaching channel in San Pablo Bay.)



But on busy weekends, you'll be required to dock perpendicular. Best to arrive and leave near/at high tide.

On the east side of Angel Island, in Ayala (Hospital) Cove there are still fore-and-aft mooring balls for day/overnight use, as well as docks for day use. (There we are: bottom row second from the left.)
