COVID-19 update: To comply with social distancing recommendations, the captain will take no more than 8 passengers. Each passenger is responsible to show up healthy and to wear a face mask.

If you are looking for a fantastic family fun-filled adventure, then you need to book with Nautilus Excursions today. Captain Ron Koyasako has been running charters for nearly 2 decades and will do his utmost to ensure you have an awesome day out on the water with him.

You’ll spend the day on a 30’ Island Hopper. This is ideal for large groups and families, as 8 can fish on her without bumping elbows. With a 480 HP Cummins engine, you’ll be at the fishing grounds before you know it – on the half day trips, the ride can be as short at 10 minutes.

On board are full safety and navigational equipment, including fishfinder. Coupled with Capt. Ron’s extensive knowledge, and you’ll be on top of the fish all day.

The fish you’ll be targeting on the half day trip include Striped Bass, Halibut, and Leopard Shark. This trip is ideal for families with children as the runtime to the fishing grounds can be as little as 10 minutes. There is no minimum age for children and life vests are provided. For infants and babies, parents will need to bring small life vests for them instead.

The full-day trip is great for catching King Salmon out of the bay. There is a longer runtime to the fishing ground, but the ride out is worth the catch! As well as King Salmon (also known as Chinook) you can expect to catch Leopard Shark, Rockfish, Striped Bass, Halibut, and Lingcod.

During the trip, you’ll be using top quality Daiwa rods and reels. The live bait you’ll use will be prepared before the trip, giving you maximum time fishing.

You are welcome to bring along food and drink (in a small cooler) on these trips. Please purchase a fishing license before the day.

Book now for an unforgettable trip with Nautilus Excursions. Capt. Ron can’t wait to show you why he loves these waters.

Fishing has always been my passion. I started Trout fishing at 2 years old, and charter boat fishing at 5 years old. I worked on charter boats for 18 years before becoming a captain. I have sportfished and commercially fished all my adult life. I enjoy seeing the thrill of a new person catching their first fish and anglers catching their personal best. My favorite species of fish to catch is Striped Bass. I fish for them year around.

6/18/21 Friday Today we had a AM charter. The wanted to catch some halibut so we tried targeting them. We found a little choppy conditions when we arrived to the grounds. We picked away at them until the bite turned on just before we needed to leave. We lost a few nice ones but that is why they call it fishing, not catching. We still ended up with a catch for the cutting board. Lauren, Thanks for arranging the charter. Looking forward to ou next trip! Captain Ron & Hunter

6/18/21 Friday We had a PM trip today. We went to the halibut grounds, but conditions had changed since we left. We found slow fishing and scratched at them till we made a catch. With time to spare we made a move and caught some nice bass and got what we needed. John, Thanks for trying the Nautilus, look forward to our next adventure. Captain Ron & Hunter

6/16/21 Wednesday Today we had an old friend charter the boat for his son Kysen’s 8th birthday. We started out on the early side, we went searching and found the bass willing And motivated to come aboard. We went looking and hooked into what we thought was the right kind ?almost, but no cigar as we parted our ways. We then changed zip codes and found the flatties on the munch with Kysen catching a 75# limit. To go with his bass limit by 6:45am. We caught what we needed and called it a day. Kyle, About time you tried the Nautilus! Thanks for the charter and see you in October! Captain Ron & Hunter
