TABLE 6: DESCRIPTION OF BOAT LAUNCHING RAMPS WITHIN BRISBANE WATER
BOAT RAMP

REMARKS
This single lane boat launching ramp has been
constructed on a shallow sandy foreshore, as such
difficulties can be experienced launching and retrieving
boats on anything but a high tide.
Signs may need to be erected informing users that the
ramp should only be used at high (high water boat
launching ramp).
