Ceasar Thunderbolt

By a coinsident stumbled over this boat type on the net. A big boat to be a SIB(well, in my opinion its a sib not a rib). Noted also here on the forum some previous discusions but not so much how it performes in tuffer wind and chop than in the marketing video. Anyone her tested one in slightly rougher condidtions?

Boat is light 120kg, and recomended engine is 90HP (weighing more than the hull) would this make it sensitive for flipping?

Here a smaller one is learning to fly"

fun on a boat is inversely proportional to size...sort of anyway

Cats usually use 50 HP engines to fly, a 90 is a exageration, that engine will rocket you to the moon, sib included. Handles rougher waters than sibs as the hull doesn't touch water at all, if drivers are not correctly distributed and balanced inside cats, can flip over waves as happens every time while racing.

Happy Sibbing

The Thunderbolt is as you say a lot larger with proper seats and everything, it would have hydraulic trim so it's as safe as you make it!
