Got south of south island at 5:10 am for slow conditions. Trolled all around south island for one nice calico. Later, found lots of busting bait near the lighthouse for another calico. Joined the fleet in the south kelp ridge area for a yellow on a live sardine, #2 circle hook, and 15 pound fluorocarbon leader. Bite died and everyone filtered north. So did we. Pickup a nicer yellow a little south of south island on an xrap 20. Picked up 3 more yellows on xraps on the inside of south island at that little harbor and north. While leaving the islands, it was a bit rough so I headed directly for Imperial beach hoping to deflect some spray. Mexican navy ship coming from near Tijuana seemed to set an intercept course for me. This ship had a helicopter pad and a red rubber boat. I changed course for the border directly and picked up the throttle. Ship changed course, rounded pukey, and seemed to be headed for the 302.
