Right now I carry a 35# Delta, a 44# Bruce, a 25# Danforth,
and a couple of small kedge anchors.
The Delta is has all chain rode. The Danforth has 25 feet of chain and 250 feet
of 5/8 Nylon rode. The Bruce has 250 feet of 5/8 Nylon (but that'll change.)
Ground tackle is an on-going area of slow improvements.
For local SF Bay conditions, the bottom is clay mud which holds really well,
(probably because it's full of mercury and heavy metals washed down from the Sierras during the Gold Rush.)
