510 Waterline is excited to launch SUP (Stand Up Paddleboard) classes out of two locations now – Marina Bay Yacht Harbor in Richmond and The South Sailing Basin at the Berkeley Marina. “Mara and I know if where we exercise isn’t convenient we won’t do it,” says Jess Parker, partner.

Kick off your week with a 510-Yoga class Monday mornings at Berkeley. Every other Wednesday morning at Berkeley take 510-SUP Adventures: Intro and More to increase your skill and efficiency. Or skip the gym and get a workout with our 510-Fitness class on the water. It’s all about building skill and building community.

“Jess and I love what we do,” says partner Mara Stonefield, “and we strive to keep building a community based around stand up paddleboarding. As many know, we want to make SUP available to all, in a supportive and healthy environment. SUP is not just a sport to us, it’s a way to be in nature while getting a full body workout. It clears the mind and calms the soul. It’s a chance to experience the Bay with new friends and old.”
