Very pleased to hear there were no serious injuries.

On that basis hopefully it is not rude to ask what the industry can learn from this incident? If an engine failure causes a near instantaneous 90 degree turn, shouldn’t we all have grave concerns about running at anything over 70 MPH in a twin engine application where the lateral moment arm of the thrust line is increased due to the offset from the centreline? –i.e. Catamarans. Motor failures are not unknown and particularly in high HP applications. If an instant 90 degree turn is the failure mode of a single motor dying how is anyone getting insurance? I suspect something must have occurred to seize the propeller. Drive systems are not my specialty so I’d be very interested to hear the opinions of driveline specialists or those whom have experienced a high velocity single motor failure on a twin engine cat.

Many thanks

I met him in the elevator and asked about his tunnel tab.. He said it was NOT being used for the run..

Said he hit a pretty good crosswind right when the engine went down, so I'm SURE that didn't help matters...

Thanks Boatally –that is valuable information and the crosswind point may be highly relevant as powerboats are essentially backward flying darts. Those old Linder hulls do run on their nose a bit and this can cause real yaw instability. The video showed quite a bow down attitude just prior to the hook and with the high X-Dim there is very little skeg in the water to help once a yaw perturbation occurs. It is not often that one has clear video footage and a driver with a good recollection of an incident so it should be possible to figure out what happened here.
