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 hed 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. Its worked up to this point and Ill 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?
