Correcting 'list'
Perhaps correcting the list is the way to go. I once read an article that suggested this fix. Use clay bricks placed as far outboard as possible in the bilge to 'level' the boat. Remove the bricks, weigh them, and have a lead 'pig' casting made with the same weight. When the bilge can be cleaned and completely dried out, perhaps during winter storage, place the 'pig' at the center of the area occupied by the bricks and secure it with epoxy and such bracing as may be necessary. When the boat is back in the water, if the 'pig' turns out to be too heavy and causes a list in the other direction, drill holes in it to remove as much lead is necessary to get the boat on an even keel. Use a collar on the bit to prevent drilling all the way through the lead and into the hull. Since one cubic foot of lead weighs about 707 pounds, you probably won't need a very large 'pig' to do the job. Another thought would be to determine whether any heavy objects, such as batteries can be repositioned to shift their weight in the right direction. If shifting the batteries results in only a partial cure, then, at least, fewer pounds of lead will be needed to complete the job.
