Hi to all,
Thank you for taking the time to reply and to give your various comments.
Very interesting point about reducing the volume below water level and therefore requiring less ballast to sit at original WL.
There would be a rise of the C of G when removing part of the keel which would mean a bigger weight would be needed compared to what was removed to compensate for this rise in C of G. This bigger weight would mean a reduction in freeboard when seeking the same righting moment and an increase in draft....? Complicated when you were trying to reduce draft in the first place...
I get the general consensus is far too much work and probably not the right way to go, but still interesting to think about.
Thanks again for all your thoughts!
