A Del Mar resident called authorities to report a suspicious boat ashore early Monday.
Eighteen men were taken into custody after a panga was discovered on Torrey Pines State Beach around 2 a.m.
U.S. Border Patrol agents say the men are originally from Mexico. No drugs were found in the boat.
Two of the men were transported to a nearby hospital.
A San Diego Coast Guard helicopter was used in the search.
