Piazza De Ferrari. Genoa, Italy. I was spent two hours and i can say it was a amazing visit. Genoa is fashion capital of yachts. Abramovich yacht Radiant was there. Cruise speed more then 75 knots and also it has a sonic guns that fire low-frequency sound waves that can burst the eardrums of approaching assailants, and a military water cannon capable of sinking an approaching boat at more than 100 yards.
