Quick MC² Gyros are air-cooled, compact and quickly exert powerful stabilizing forces, spinning up to full power in about 10 minutes to reduce roll up to 95 percent in some boats. The flywheel rotates horizontally on twin bearings, evenly distributing weight and wear rather than putting the stress on a single bearing as in vertical-rotation models. Quick Gyros make less noise than competitors and do not require through-hulls for water cooling, making installation faster and cheaper. Multiple units can be combined to stabilize large yachts. They’re effective at anchor and while underway.
