The Henrietta sank in 1940 after running onto a basalt reef during a squall, leaving a scattering of pig-iron ballast, star pickets, and the ship's rudder in just 3–4 metres of water. The Diane rests nearby in similar depth. These heritage-listed wrecks are easily accessible to confident snorkelers, who can swim over the low-profile mounds and explore the artificial reef they've created, dotted with colourful sponges, reef fish, and crustaceans. A rare opportunity to combine maritime history with a shore-entry snorkel in protected bay waters.","intermediate","published",{"name":58,"amplitude":74,"phase":90,"latitude":22,"model":106,"epoch":107},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[75,76,77,78,79,80,81,82,83,84,85,86,87,88,89],0.010287218776962198,0.00874402608903705,0.15453300276379128,0.008239857875919998,0.26853473195678357,0.006887226457078093,0.008427956725218202,0.001297944725860009,0.027218689670413552,0.06988540431598464,0.032465330445844126,0.031292324244232,0.018450372734665724,0.10643910085038652,0.019427423936161356,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],46.3615731475033,315.96438784720755,293.4336930103717,27.367047632708704,23.280422124734457,248.08722204026685,149.97589368137466,208.2724210232151,33.609532421220536,287.8810536776573,289.00812691885557,278.81052665657313,10.080460675656354,224.32962692224697,196.73028601046434,"EOT20","1992-01-01T00:00:00Z",[109,114,119,122,125,128,131,136,139],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Slippery uneven rocks","The sanctuary's exposed rocky reefs and basalt platforms can be extremely slippery when wet.
