10/26/25 Sunday Today we had a morning half day charter. The family charter wanted to try salt water fishing and what it has to offer. We found a nice school of bass that responded to our chum. Most had never caught keeper stripers and caught a few personal bests. We got what we needed and caught and released many for the memories before it was time to go. Moua, Thanks for trying the Nautilus! Captain Ron & Braden

11/23/25 Sunday We had a combo trip today. The swell was up today but the winds were low. We made the long run for the fishing area and found the fish but Mal de Mere came aboard the rocking and rolling dance floor and made it hard on the boys. We made a catch and ran to the crabbing grounds and found our crabs! Patrick, It was a pleasure having your group on the water, looking forward to our next adventure! Captain Ron

Amazing day on the water

VERIFIED   Half Day Trip (AM) on July 4, 2025
Did catch all we wanted. But was not from the lack of trying. Sometimes they donโ€™t bite! Loved it and would book them again
