End of the story, at least as of today!
Patty was not satisfied with her splice of 8 plait half inch rope to chain, she could not get a nice narrow taper. We just did not see that working well.
So, we now have 100 feet of 1/4" G4 chain in the locker. Came in through the windlass without a hitch. I will be using 15 feet of three plait dock line as the snubber, and will probably use a rolling hitch knot rather than a chain hook.
First trial will be Wednesday, August 19, the night before crabbing opens in Washington area 7 north. We will be anchored in Birch Bay Wednesday through Monday, pulling the anchor twice a day to set and check pots!
