329 Main St. Seal Beach, CA
Harbour makes the claim that their Seal Beach shop is the world’s oldest continually operating board manufacturing location.
Rich Harbour, the name behind the brand, started shaping boards back in 1959 so no matter the validity of their historical claim, they play a major role in California surf history.
Today the shop has artifacts scattered around the walls, on shelves, and hanging from the ceiling. It also has new boards on the racks, being shaped in the back, and available online. The place is not a museum but a functioning shop.
It is crowded with tourists and surfers, the two not being mutually exclusive, parking is tight, but you should visit.
