West Marine Antioch is the leading marine supply store in Antioch, Pittsburg, and the surrounding area. Located by the marinas on the California Delta, our store is a quick stop for anglers, boaters, and paddlers before enjoying a wonderful day on the water. Grab a new fishing rod and reel before heading out to target catfish, bass, and stripers on the Sacramento-San Joaquin Delta. Sailors and boaters can tune up their outboard motors, stock up on safety equipment, and find watersport accessories. Paddlers enjoy exploring the tranquil canals and can find paddles and PFDs in our kayak shop.
