| Boat Name: Ocean Trek, a catamaran style vessel that measures 18 meters in length, powered by two 6-71 Detroit diesel engines giving a top speed of 10 knots. With the ocean swells still affecting the entrance, the afternoon dive was at Murray's Sandline, to hunt for baby Port Jackson Sharks! I skipped this dive and had an afternoon nap to recover from the long drive from Melbourne. Then it was time for a pre-dinner twighlight dive, also at Murray's Sandline. On the bottom we found Skate, Flathead, Banjos and Sea Pens dotted about. There were some old survey stakes enveloped in Queen Anne Scallops. There were half a dozen baby PJ’s around the base. Then we found many more around and between other stakes. Finding the boat was made easier by the noise of the generator, and as we approached I saw a cloud of small Chinaman Leatherjackets. There was a beautiful little Butterfly Gurnard, and Squid hunting in the light pool at the back of the boat. Back aboard, showered and refreshed, we sat down to another superb meal, chatter and laughs. By eleven ‘o clock almost everybody had hit their bunks, so the generator shut down early. |
