About Us

Bay Marine Supply is based in San Diego, California, and specializes in specialty electrical and solar equipment for boats, RVs, service vehicles, and off-grid solar installations. We are a stocking distributor for Sterling Power and Victron Energy, and an authorized dealer for a wide variety of brands. Our tech staff is intimately familiar with the function and specifications of all products that we sell, and we fully support all components purchased from us! Our goal is to give you a level of expertise that you simply won't find at the mega-stores, and we're happy to work with you on your equipment choices both before and after your purchase. While we'd really rather be sailing or camping, we totally enjoy bringing our knowledge - and great service - to the marine and RV parts marketplace.

A note on our prices: we think boating and RVing and solar installations cost too darn much! And since we don't have a lot of overhead, and we're privately owned, we're in a position to do something about it. We do get asked quite often if our prices are real, and the answer is yes, though we'll be happy to raise them on request.

Just drop us an e-mail or call us at 619-320-5899. We can get pretty busy at times, but leave us a message and we will get back to you as quickly as possible. Please note that we are not a retail location, and unfortunately cannot accommodate walk-in inquiries, in-person transactions, or perform in-situ component troubleshooting or system design. We do offer will-call as an option for orders placed online, though! We also have a (very) short list of local trusted independent installers that we would be happy to refer you to as well should you need design or installation assistance!
