this time of year, the 'out flow' + 'outgoing tide' = stronger than expected current; trying to crab or fish before low isn't worth it. incoming tide to a high tide is better but the 'out flow' reduces high slack to almost nothing.
( I was out there March 8 during the outgoing tide on my Oasis and it was really ripping out around the #7 green tower, I had no issues making headway against it but it took some effort. There were also several stray traps caught up in the submerged jetty, with loose ropes swirling around. I got a limit of crab by working the area west of the submerged jetty, where the current is less, also just upstream from the #7 marker but still towards the west slightly, out of the main channel, lots of 30' water in there. My traps do have extra weight on the bottom, 2 to 3# of it. All my crabs were >6" but none over 6.5", the commercial boats have cleared out the larger crabs. I was also targeting lingcod but didn't find any).
