THE boat building and restoration supplier in So. Cal. It's where all the professionals and serious amateurs purchase chemicals, fasteners, electrical, deck fittings, interior fixtures, and on and on. Professional staff for straight advice. The real deal.

You gotta love these guys! I work as a yacht technician and find myself on parts runs here all the time. The staff is super helpful and personable. They know their stuff! Unlike some other marine parts stores that have "non boaters" as staff. Also for the size of the store, the selection is very impressive.

The best place in Southern California for marine parts. Dan has all the knowledge and skills to help you fix/install anything. On multiple occasions, he has taken the time to make sure I have everything needed to complete the job. Saving me time and trips to get what I need. Thanks again!

A landmark of the boating community in San Diego. Competent help available. A great selection of REAL boat parts here and at their sister sailboat store (Downwind Marine). I have done business with them for 30+ years and always a good experience.
