Northbound off Baja, heading for Ensenada, wind 25kts on the nose, seas 8ft, cloudy, misty, no visibility. Motoring into it. Alternator stops working, batteries go down, radar kaput, chartplotter kaput. Engine panel guages not working, no fuel or temp gauges. Autopilot quits. Low on fuel. Trying to make a night approach to the southern entrance, 2.5 miles wide, according to all the best info. Can't reconcile lighthouses, 3 of them, with chart info. Use a handheld GPS and paper charts, creep ahead, watching the lighthouses slowly move aft, find our way into the harbor, drop anchor right off Baja Naval. I had a severe stomach ache, brought on by nerves, that took a liter of ginger ale and whole packet of crackers to moderate. There were others on that trip to Mexico; on deck at night, wind 25kts, trying to bring the flogging genoa down when the furling drum jammed, twice. Engine quitting in the middle of the entrance to Turtle Bay, also twice, and a host of others, but I'm still sailing and still want to go back to Mexico. Someone once said "That which doesn't kill you makes you stronger." I believe it.
