Just did the trip across to Nusa Lembongan in Bali fastest passenger boat Kai koa 650hp with just myself the Mrs and the skipper the on-board GPS was flashing between 45-49 knots or around 90kph. Skipper told me it can do 110kph but the boss monitors the ECU data and is rightly not happy with running the motors flat out. Air suspension seats, self inflating life jackets. If you're over here book it you won't be sorry.
