Print In the waters off San Diego, the smuggling boats often cloak their cargoes of migrants under cover of darkness. Only the hum of the panga boat engines signals their approach to slumbering coastal neighborhoods. But on Sunday morning it was clear and bright when Cale Foy spotted a horrible sight unfolding at the base of the craggy cliffs of Point Loma. A 40-foot trawler-style boat had crashed into the rocks, spilling men and women and a teenager into the pounding waves and a rip current so strong that it was dragging some farther from shore. Foy, a naval aircrewman on a hike with his family, didn’t hesitate to dive into the choppy surf.
