 From the newsgroup, rec.boats.cruising:
--------------------------------------------------------------------------------------------------------------------
Late last night, a huge sailboat came ghosting into this marina.
David, her owner and captain usually sails Aratinga, a 60 foot Alden
with an 80 foot mast, outside on the open ocean but he said he thought
this year he’d like to try the ICW. Now…this is quite the
accomplishment, given that the fixed bridge heights on the ICW are all
around 65 feet. David ingeniously rigged up a way of tilting his boat
over so that she “slides” under the bridges, healed up on an angle. He
has two one-ton (yes, 1 ton) thick rubber bags of water hanging midway
up his mast. His boat has a slight tilt to starboard anyways and when
he wants to tilt Aratinga over to pass under a bridge, he lets the
line out on these bags of water so they hang over the side and that
increases his starboard list. He figures that to cut 10-15 feet off
his mast, he has to let the bags hang out 10-15 feet to starboard.
It’s worked up to this point and I’ll bet this New Zealander will be
the talk of the ICW for years to come.

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 spinnaker 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 spinnaker pole
and heeled over about 3 deg according to the inclinometer.

All in all, not a very successful experiment.

I'm thinking to rig up a block and tackle 
arrangement. Hoist same up the spinnaker halyard 
then try hoisting the buckets. Hopefully getting 
them out farther will heel a lot more.

But then is it worth it? Doing the math says I 
have to heel 35 deg to lose 1 ft. of my 6 1/2 ft 
draft. Or will I lose more because the keel will "lift" as she heels?
