Named after a submerged boat-shaped rock formation, this reef features extensive low-relief limestone with a labyrinth of nooks, crannies, crevices, and small swim-throughs that shelter an incredible diversity of marine life. Accessible as a shore dive from the beach south of the harbour, the reef drops gradually and rewards snorkelers with the feel of entering their own private aquarium. The site is popular with both divers and snorkelers for its proximity to Perth, easy entry, and consistently good visibility in calm conditions.","intermediate",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.004349365941535819,0.00926741896775185,0.1666072050159385,0.01344304367083093,0.055314134950340516,0.004960114534354051,0.005349492418752834,0.004627878303902165,0.013270664839166953,0.1223946399999975,0.050422269524137565,0.022978820472093663,0.013701882408665931,0.04189887111239728,0.003185717441722617,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],32.465438398763304,227.72670912886508,181.79600509759723,41.14901925599287,59.14250614771857,127.84745873268706,36.210051294030364,217.53243682831817,104.15965933221861,175.95879501515287,171.12388371159034,172.82430128822807,318.29751286006194,65.03368873326534,220.8471923124807,"EOT20","1992-01-01T00:00:00Z",[71,77,81,86,89,92],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":76},"Boat traffic","The reef is near Hillarys Boat Harbour entrance, with boat traffic in the area.
