Gulf Harbour Hammerhead is a marina at Gulf Harbour on the Whangaparāoa Peninsula in Rodney, north of Auckland, and it holds a 4.6 rating on Google. A good marina is more than a car park for boats: shelter from the prevailing wind, depth at low tide and a handy fuel dock matter more than anything on a brochure. Around the Hauraki Gulf, summer visitor berths fill quickly, so regulars book ahead and check lines and fenders before a southwesterly arrives. Hulls foul fast in these warm waters, so owners plan on haul-out and antifouling every year to eighteen months, which makes a marina's hardstand and yard services well worth weighing up. Set where it is, Gulf Harbour Hammerhead leaves peninsula boaties a short run to the gulf's islands and fishing grounds.
