Twin Keel vs Bulb Keel
Have to agree that it would be simpler to leave the lead exposed on the keel and box in the bilge/garboards with steel & floors and bolt the lead assembly to it. Lead is a great cushion if you hit something hard. (We know -- but that''s another story...) If you poke a hole in a steel casing that''s holding your ballast you can develop some nasty problems before you know it. Woodenboat has had several articles on pouring lead keels and moving them around with farm tractors, winches, and tackles. Sounds quite straightforward if you think it through. Unless you absolutely require shallow draft, twin keels are not the way to go. They''re lighter, individually, but imagine the fun you could have making sure they''re both parallel with the hull and each other...!
