Vessel operators are advised that due to works associated with the construction of a new Marina, an exclusion zone and vessel operating restrictions are in effect on the waters of Shell Cove Marina and Tasman Sea in the vicinity of Shell Cove from 15 March 2021 until September 2021.


The Exclusion Zone (‘the Zone’) comprises the entirety of the waters within the confluence of Shell Cove Marina and extending 30 metres outside the breakwaters into the Tasman Sea on the dates detailed above.

The Zone will be enacted as required by the construction works and marked by the presence of local buoyage and signage, and patrolled by authorised officers and control vessels.

Vessel operators are further advised:

  • divers may be in the water during the works and vessels associated with the diving operations will be displaying an Alpha Flag, which is a white beside blue flag with the blue section featuring a swallow tail.
  • Vessels engaged in the contruction works may display Restricted In Ability to Manoueuvre shapes and lights indicated during the day by three shapes in a vertical line comprising ball–diamond–ball, and during the night or at times of restricted visibility by a series of three lights in a vertical line comprising red–white–red.
  • Vessels engaged in construction works that require a stable or calm state may display an ‘R’ over ‘Y flag (Romeo Yankee) which indicates all other vessel traffic must proceed at a slow speed that creates no wash when passing. An ‘R’ flag is indiacted by a yellow cross (vertical and horizontal lines) on a red background, and a ‘Y’ flag is indicated by alternating red and yellow diagonal lines.

All vessel operators and persons using the waters specified above should keep a proper lookout, comply with local buoyage and signage, and exercise extreme caution when navigating near the works.
