Tule Reed Canoe Navigation Across the Bay

Long before the arrival of sailing ships and steam ferries, the tranquil waters of San Diego Bay and the Coronado shoreline were navigated by Kumeyaay mariners in swift, lightweight canoes known as ha kwai (tule balsa boats). Constructed by tightly bundling and binding buoyant tule reeds harvested from freshwater river mouths, these remarkable double-ended watercraft measured up to twenty feet in length and were propelled with double-bladed wooden paddles.

Kumeyaay navigators utilized these resilient canoes to traverse the calm tidal waters of the bay, fishing with bone hooks and woven nets and trading valuable coastal commodities with inland communities. Dried fish, smoked shellfish, abalone shell jewelry, and coastal salt cakes were transported across the harbor to mainland villages, where they were exchanged for mountain acorn flour, pine nuts, chert stone tools, and obsidian from the eastern deserts.

Archaeological evidence confirms that these ancient maritime trade corridors extended along the Pacific coast and southward toward Baja California. The mastery of tule boatbuilding and bay navigation demonstrated the sophisticated aquatic knowledge and trade networks of the Kumeyaay, who made the bay and peninsula a thriving regional trade crossroads.
