I'm more interested in their use to recover from groundings than bridge

Me too Larry. I'm in a situation where I need to move Valkyrie to
another marina that's a bit shallow for my 6-1/2 ft. draft. It is
soft, silted mud. Experience tells me I can push through as much as 2
ft of it, which is about what I'll be lacking.

However....

I rigged up 3 25-gal "buckets". I figured 20 gal each, so a total of
500 lbs. Hooked 'um up to the spinaker halyard and started hoisting.
WHEW, it gets difficult, then impossible. Ran the halyard to the
manual anchor windless. Lots of tension with creaking and groaning,
then got worried when bucket # 3 was half out the water.

I think my pulley up there must be binding because it was puting a
HECK of a lot of tension on the halyard, then a second or two later
the buckets would move up, then seem to kind of "creep" up an inch or
two. Seems to me 500 lbs shouldn't take that much effort, especially
using a 2-speed anchor windless????

I was in the slip, stuck there in fact since the water was waaaay low.
Shoved the buckets out about 8 ft. from the boat with a spinaker pole
and heeled over about 3 deg according to the inclinometer.

All in all, not a very sucessful experiment.

Seems you need to run the spinnaker halyard differently as it shouldn't
bind like that.

Once that's sorted out, try pulling the weight further out with another
boat or a dink. 8' doesn't give much moment.

OR wait until you get a blow from the right direction to give you
higher water. I forget where you're sailing, but 'round here, a strong
southerly will give us a couple of extra feet, a northerly can make it
impossible to move from our slip (we draw 4'2")
