We Keep You on the Water,
Season After Season.
Factory-trained technicians, genuine parts, and a service team customers trust enough to call themselves "customers for life." From winterization to full repair — done right, right here in Discovery Bay.
A Full-Service Shop,
Run by Real Boaters
Buying the boat is only the beginning. Our full-service repair facility keeps your investment running right. Handled by technicians who not only fix boats, they own them and run the same Delta water you do. As a factory-authorized dealer, we know the brands we service inside and out — and we treat every boat that rolls into the shop, ours or not, like it's about to head out for the best weekend of the season.

Hull, Gelcoat & Fiberglass
