I am thinking of adding weight to my keel. On my boat the trailing edge of my keel is hollow and I could probably fit about five gallons of water down there or equivalent lead pellets. Has anyone done this? Sounds alot easier than adding a keel blub (around 2k) but haven't determined how much lead will fit and whether that amount of weight would make any difference. This might mean reinforcing the trailing edge of the keel as there really isn't alot of material there, I have reglassed this edge once before.
