The charts for Stuart Channel indicate a rock  at a depth of 8.5 Meters. After quite a bit of searching we could only find a bottom profile that came up to about 18 meters. Tossing the anchor in and rolling off the boat we headed down. Reaching the bottom we found a rather smooth large rock hummock at indeed 18 meters.

After doing a survey of the area surrounding our anchor, we headed east, then North. The area has quite a lot of good sized Orange Plumose The perimter of the rock is in about 20 meters of water. Although we continued to see lots of Plumose through out the dive we only saw a hand full of rock fish. They all appeared to be black rock fish sometimes called Sea bass, around here. Heading some distance North we finally came around the north end of the rock and started to head back in a south west direction. 

We did find the odd Sea cucumber and Nudibranch, and although we saw lots of crab shell, we did not see any crab. Now whether they have been fished out  by people or Octopus there is no way to know. Swimming for some time it appeared as if we were coming up on the southern tip of the rock we had been swimming when another large rock appeared in the distance a little farther west. Heading in that direction we found some lost prawn and crab traps. Heading south west along this new rock was where we found a Sail Fin Sculpin about 6 to 8 inches long, hence the name of the rocks. We followed this new rock around until we got to an area that dropped off where we headed down to about 25 meters. Here we found quite a lot of interesting topology, a shear wall with more rock fish, brittle stars, and sea cucumber. The rock face we were swimming along broke up into several Large boulders that you could swim around and through, the terrain then started to lead us back North past the crab traps and towards our point of entry. Swimming through more plumose forests, we came back up to the 18 meter level where getting low on air we started our ascent.
