The "Ohana" cruises the Pacific northwest, and is a 30' sloop. We use a 35#
cqr with 20' chain and nylon rode, and the windlass is the mast winch. We
have anchored in some pretty rambunctious situations, and have been
spared the distress of a dragged anchor on most occasions. One time we
were in the pub at Garden Bay (Pender Harbour) during a blow reviewing
photos taken earlier from the digital camera and noticed the boat had moved
a substantial distance towards the docks. We raced back in the dink, but she
didn't move again. I have found that the boat moves a bit until the anchor
"soaks" into the bottom. She then holds fiercely. If the wind shifts about to
opposite compass points, the anchor may have to reset itself, but it still holds
bottom.
There was one situation during a qualicum at Lesquiti Island that had me up
all night evaluating the drag potential. The wind and waves were making the
boat hobbyhorse and wrestle about in rodeo fashion, and I used most of my
scope in an attempt to relieve the tension. I have fussed with a snubber, but I
find that it hasn't helped all that much. Maybe a bridle is better? When
addressing the issue of relief for the rode under extreme conditions, friends of
mine have a solution for this that is worth investigating.
They use 20# lead fishing weights that they slide down the rode on a shackle
in advance of potential weather situations, or in short scope areas: each one
on a separate line. The idea behind the weights is to :
1. decrease the angle of the rode to the bottom
2. increase the weight and forgiveness of the rode
While admittedly a low-tech solution I think it has a place in the discussion.
We, here in the northwest, sail in sheltered waters more of the time than some
of you in this group (I imagine). For me? In the spring I hope to sail to Barkley
Sound, on the west coast of Vancouver Island, where Mel (Port Townsend
living history) said: "Your boat goes up and down, up and down." Does
anyone want to discuss chafe?
