About the ‘El Cat’

The El Cat, built right here in Moss Landing, is a fully electric, 32 passenger, Coast Guard-certified vessel. This is a custom 37’ catamaran built and designed especially for the waters of our very own Elkhorn Slough. Joe Kitchell at Left Coast Composites used a proprietary fiberglass/carbon fiber vacuum infusion system to build an extremely strong, light-weight catamaran powered by 2 independent 20 horse power Elco electric motors running on 48 volts.

We can accommodate private groups as large as 32 and will schedule a private charter tailored to fit your needs.

School Groups

As the boat can seat 32 passengers and is a safe platform for kids of all ages we are a great option for school groups. Interested in field trips to study ecology, natural history, wildlife, birdwatching, stewarding our environment and so much more? We are excited to accommodate school groups and have special groups rates for education.

Birding Tours

The Elkhorn Slough is visited by over 340 species of birds throughout the year. This tranquil estuary has such an abundant variety of habitat for so many unique species that it is a birder’s paradise! Photographers love our boat because of the lack of vibration from the electric motors. Contact us for the special birder group rate. Click here for link to Audubon Elkhorn Slough site.

John, Daly City, CA

My family of 4 booked a tour with Monterey Bay Eco Tours after checking out other tour companies. We totally enjoyed the day. Our guide made sure we were comfortable, and was very accommodating with our children. We had a fabulous day and would recommend Monterey Bay Eco Tours to anyone considering an Elkhorn Slough Tour.

Anita, Phoenix, AZ

This was our fourth trip with Monterey Bay Eco Tours and it lived up to our very high expectations. The ship was quiet, clean, comfortable, and excellently crewed. A shout-out to our wonderfully informed guide who pointed out local flora and fauna. Excellent!
