Hi all,
The speedboat Runs a Jetdrive system, most Jetdrive systems have a panel or a flap that drops down at the exit of the steering system this enables the thrust to be re-directed down and towards the front of the boat, in military applications this feature is used to perform a 'splash down' which forces the front of the boat into the water and thus creates a large wave that travels forward from the front of the boat, this also creates a large amount of spray which helps to hide the movement of the boat and can be used to create a 'screen' when under fire. to see what i mean search follow this link.

This link will take you to a video that at about the 2 minute mark shows what happens when the panels are dropped.
it would be good to have this feature in ArmA 3 as it adds more realism to the Jetdriven boats.
