Description
For single-spar designs which are gravitationally stable (C_g below C_b), rather than having the ballast at the bottom of the spar, we could hang it from the spar for additional stability.
Detail
- This allows for much greater leverage of the ballast on the center of gravity, therefore allowing for less ballast and greater topside weight, without the additional cost of a long spar.
- Leads to stability issues when undeployed, however.
- It scares Patri that the seastead will be made unstable if ballast cables are severed.
- ? Is this needed/useful for metacentrically-stable designs, such as multi-column?
In this picture, imagine much longer cords for the hanging buoyancy:
