Preformed foundation support for a marine vessel gyro-stabilization system

A preformed foundation support for a vessel gyro-stabilization system generating sufficient torque to stabilize a vessel against rolling of the vessel in waves, comprising:

• a first side support;
• a second side support;
• a third side support;
• and
• a fourth side support, wherein the side supports define an opening for accommodating at least a portion of the vessel gyro-stabilization system, and wherein at least one of the first, second, third, and fourth side supports comprise a cuttable portion for custom fitting the preformed foundation support in the vessel, wherein the cuttable portion of the side supports are formed of saw cuttable molded fiberglass and cuttable so that the preformed foundation support fits into existing hull structures of the vessel and the cutting of the sides supports fits the preformed foundation support into the existing hull rigidly so that when affixed with bonding material to the existing hull the preformed foundation supports the transfer of force to the existing hull to support the weight and torque of the vessel gyro-stabilization system to reduce rolling of the vessel in waves.
