Love seeing the grandeur of huge sea mammals. In this case, we were cruising North from Frailes to Muertos about 5 miles off Baja and I saw a whale in from of us. He was just cruising South on the surface and I actually had to alter course a bit to miss hitting him. We passed each other by about 30 yards. He seemed completely unpurturbed by us. I think it was a humpback.
