Hi Bill,
Last first: The green circles on the water are gone.
The good news is that the hidden triggers of ’08 are not hidden; they are marked on the chart by green sunbursts.
To deploy a RHIB from the mother ship, click the rightmost button in the bottom right of the screen. You will see one or two boat icons apear above that button, click one to make a RHIB appear in the water next to the ship.
An icon for the RHIB will be at the left edge of the screen, as in ’08. Click on it to take control of the boat.
Regards,
Marty
