Meet our boats

Humboldt, Island Time, and Camarão, our vessels that will make you feel at home



up to 20 divers/24 guests


The Humboldt is a scuba diver’s dream dayboat. We dare to say the most popular San Diego dive boat. Co-designed by one of Waterhorse Charters’ founding fathers, our largest vessel is a prime example of Newton’s acclaimed dive special model.

They are recognizably so safe that the San Carlos’ Coast Guard only approved of a Newton 46’ to sail through hurricanes. Not to mention, Newtons are the main dive boat featured on the popular Art To Media Dive Maps.

“The best day boat I’ve ever been on. Plenty of room to sit, eat, move around, store my camera and gear, full bathroom, and even little tables to eat or nap after the fun.”

Meet our latest nautical star and sistership to the beloved Humboldt. This 36' Newton gem features an enclosed galley, three snug bunks, a breezy second deck, and not one, but two hot showers for post-dive warmth.

A chance sauna encounter between her former owner and one of our diving patrons sparked the shift — a conversation that led Orion to Waterhorse Charters and her new chapter as a San Diego diving and cruising boat.

*We're in the process of reinstating its Coast Guard COI, aiming to expand its capacity from 6 to an estimated 12 divers/18 guests by June 2024.

Island Time

up to 12 guests


Meet Island Time, the ultimate 32' pontoon for your Mission Bay fun! With ample space to mingle, party, unwind, and entertain, it's perfect for groups of up to 12.

Once drifting in a Middle American freshwater quarry, Island Time longed to meet saltier waters. Lucky for her, a kind San Diegan came to the rescue, whisking her away and sprucing her up with love and care.

Now, join us as we transform Island Time into the floating island paradise of your dreams. Kick back, relax, and let's get to know this beauty together!

Which boat...

should I charter?

It’s totally up to you to decide which boat fits your group’s needs better. The main differences between the two boats are their capacity and some of their amenities (e.g. Humboldt has a hot shower and an inboard air compressor, the Camarão doesn't have either).

If your group size allows for it, we recommend the following:

  • Scuba diving: Humboldt
  • Snorkeling: Orion
  • Freediving: Orion
  • Wildlife watching: Humboldt
  • Party cruises: Humboldt/Island Time

is my public charter on?

On our public trip schedule, we start most trips with a capacity of 6 guests, wich is the current capacity of the Orion. When we hit that guest count and if our schedule allows for it, we automatically 'bump' that trip to the Humboldt, and open up another 14 spots.

If you have physical special needs, please reach out to us and we’ll make sure to accommodate you on the right boat for you.


Don't want to charter a full boat?

No problem! Our public charters run weekly to San Diego scuba diving and freediving dive sites. To join those trips, all you have to do is book your spot online.
