7/31/26 Friday Today we had a birthday party aboard the Nautilus. We started our day with slow fishing. The water was a bit muddy with the large tides. As the tide slowed. We caught a couple and as the tide switched the bass bit with a few doubles and even a triple. We got what we needed as the buzzer ended our half day trip! Alex, Thanks for trying the Nautilus!

Thursday 7/30/26 We had our annual charter for some fishing. The waters outside were a bit challenging, we prospected a little outside but didn’t wet a line and aimed the bow to more sheltered waters. We started out slow with the bass, but with the change of tide, so did the stripers.we got what we needed in short order. We made a move searching for the unicorn, stopping on a nice mark. We had WFO sharks and rays for a couple of hours as they bit with reckless abandon, not a chance for the ghosts to find our baits. Doug, Thanks for the charter! Captain Ron & Mike

7/25/26 Saturday Today we had some repeat customers out for a day on the bay. We looked at the forecast and thought better than to venture too far out the gate. We found some biters and stayed with them until we caught what we needed. We tried the close bottom fishing spots, but the swell had them hunkered down. Looked at a few ghost towns and only found a baby Casper before calling it quits. Zhicheng, Thanks for the charter! Captain Ron & Mike
