[C38] tide reversals in SFB

[Peggy Droesch]

Michelle,

For what it’s worth, China Camp is the only place that we’ve had this issue, & it is an issue every time. Our lovely tidal currents must do a crazy dance in San Pablo Bay. Wouldn’t be surprised if those two islets off McNear’s (The Sisters) had something to do with it.

We use a 33# Danforth & about 60' of chain rode. Small (10#?) kellet on the rope rode prevented a wrap once, didn’t another time - a larger one would probably work better.

If I had my druthers I’d go to 100' of chain at the very least - even better, lose the rope rode entirely - but talking the spouse into putting that much weight in the anchor locker of his beer can racer is going to be a challenge :-)

After some net surfing and post-event debriefing, we've learned (a) we need more chain rode and (b) we need a 15-20lb kellet to weigh down the rope rode and theoretically keep it plumb and away from the keel at turning tide.

After the first mishap, I downloaded a free anchor dragging app to my iPhone (Drag Queen) and set it so we could get some sleep. It woke us for the second wrap and drag.

We've anchored Dulcinea at Clipper Cove, Treasure Island and didn't have this happen. Perhaps we've been lucky the lee of the island is more protected from tidal flux than San Pablo Bay. We've anchored our Ranger 23 in many places and have never had this happen to Rigel.  Lessons learned! The only fouls were, well, the anchors, and we snapped one of our winch handles trying to grind in the hooks on our manual windlass that has no mechanical advantage, straight 1:1. Woof.

We've now downloaded a book on anchoring to learn more and will definitely go back to China Camp, with more knowledge and more tackle tools better prepared next time!

The GPS alarm awoke me for the first two, and I happened to awake during the third, about 4 am. The final reversal came during morning coffee. No anchor drags, we were lucky.

Twice in the night (once around 00:30 ~3 hours after setting anchor and 2hrs to high tide, the other this morning around 8:30a) Dulcinea had spun herself and wrapped her ground tackle around her keel and dragged anchor. It was no fun trying to undo the mess, twice. Thankfully we have a backup danforth that we dropped to slow the drag and give us time and slack on the primary tackle to untangle the keel.
