Sitting in depths from 5 to 36 metres, the wreck is encrusted with vibrant sponge and coral growth and is now a thriving marine habitat. Snorkellers can explore the upper superstructure from the surface, while divers follow an interpretive trail past remnants of Vietnam War shellfire and plaques identifying the marine ecosystem that has colonised the wreck. Located 500 metres southwest of Seal Island, Albany's signature wreck site offers an unforgettable blend of maritime history and underwater abundance.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.009299306194575046,0.008385305470120374,0.17678847014443516,0.032206989038425234,0.07827889963031673,0.0032741113204419747,0.002654178190835447,0.0049320964490425605,0.034688355624342755,0.13383522580677998,0.05374989465718791,0.029985540208885574,0.011425446288905926,0.10004812450536767,0.008729685454637712,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],114.86685905797752,220.613969581341,208.97386295349793,74.46408155286045,99.13363767066683,293.1525578967762,95.29234105153432,228.94364224040405,146.83173362825485,198.21717724904315,203.88603170901763,191.87723532035014,338.54106646463293,91.0515335843324,133.10044205527385,"EOT20","1992-01-01T00:00:00Z",[110,115,121,124],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Strong currents in King George Sound","Tidal currents can run strongly through the Sound, especially around Seal Island and the wreck.
