One more consideration, if the final keep configuration adds to the original
righting moment, you may want to reinforce the keel stub.  If you just cut
off 600 lbs of lead and add a 600 lb bulb, it won’t be an issue.  Most of
the time you’re just trying to maintain the original righting moment.  

 

If you cut off 600 lbs and add a 1200 lb bulb, the keel joint will be more
significantly stressed than the original design.  I reinforced the keel stub
when we R&R’d the keel on my boat.  It had hairline cracks and benefited
from a little extra glass work.   Having an engineer do the calculations is
just common sense.

If adding significant weight to the keel (increasing the righting moment),
then you should take into account the increased load on the rig.
