The team

Christian Cavanaugh

Captain, Owner

As a young boy Christian lived to fish. Every chance he had, he was down at the docks working his way onto one of the charter boats. In 2005 he left the Bay Area to attend the University of Maine.

After college he was lucky enough to spend four seasons playing professional basketball in Europe. Throughout it all, he never lost his love for fishing and is thrilled to be back on the waters he's always called home.

Christian has been a deck hand on the Outer Limits and several other Sausalito party boats for over 15 years. Being 6'8" with a 7 foot wing span, he's earned the nickname "stretch" for his ability to net fish, long distances from the boat. In 2013 he passed his 100 ton masters exam and became a licensed captain. His passion and dedication show in his work as well as his catch success rate!

Ryan Ash


Captain Ryan has been fishing since he could walk. During his college career at CSU Sacramento, where he finished his bachelor of science in recreation & leisure studies, he was introduced to chasing fall run salmon on the local Sacramento and American Rivers.

It wasn’t long before he chased these hard fighting salmon to the source and made his way to the Pacific ocean where he found his passion and love of fishing on the big blue. Working with customers on a one on one basis, and his proficiency of catching fish has landed him a top spot with renowned Charter Boat Operation, Big C.

Captain Ryan has found his home on the Chasin Crustacean where he has transformed his experience, knowledge and passion into being a driven and results oriented Captain.

Bubba (Richard Foster)

Deck Hand

As a young boy he loved to go fishing with his dad and family. When he got older he started working on the charter boats in the East Bay. He came to work for the Outer Limits in 2017. He has a great love of fishing and fishes on his days off.

He's a perfect fit for the Outer Limits because he is great with making people have a memorable experience. He stands out when working with young children.

What time do we leave?

Whale watching trips depart at 8:00am, half day trips return by noon, and full day trips return by 3:00pm. Fishing trips check-in between 5–5:15am and return by 3:00pm.

What should I wear?

Dress in layers. It’s typically cold in the morning and warms up as the day goes on. Pants, jackets and sneakers are best. Don’t forget sunscreen and sunglasses! Binoculars are a great addition for the whale watching trips, if you have some! 

Do I need a fishing license?

Yes, you need to purchase a one day fishing license for your trip (unless you have an annual license) through the California Department of Fish and Wildlife.

Will I catch a fish?

Our success rate is extremely high and we limit the amount of passengers to increase the odds of YOU catching a fish. However, it’s never a guarantee. We will give it our all to ensure you go home happy.

Will we see whales?

We have a high success rate of seeing whales on these trips. We also target lots of other amazing marine life and birds that are unique to our coastline.

What if I get seasick?

If prone to seasickness, we suggest you take dramamine prior to arrival (1-2 hours).

Should I bring food?

Yes. Bring whatever you would like to eat or drink for the day.

Can I bring alcohol?

Beer and wine is allowed, but we have a strict no hard alcohol policy.

Are your trips family friendly?

We provide a fun, family friendly atmosphere and would gladly welcome kids over the age of 5 on board for fishing and whale watching. (We recommend the half day for whale watching for children).
