A buoy has an upper float 1 and a lower stabilizer 2 depending from the base 3 of the float 1. The stabilizer 2 preferably comprises a plurality of vertical plates 4 and is configured to increase pitch inertia whilst having minimal effect on heave inertia. Particularly applicable as a control buoy in offshore engineering for carrying an umbilical for transmitting signals, power or fluid to a sub-sea well.
