Island Packers was my first thought too. I did a Channel Islands trip with them, though from Oxnard, not Ventura and enjoyed it very much. This is tragic. Hope they are able to rescue more people from that boat.
Could be a Scuba Charter
Island Packers is great. Id recommend them to anyone. Since Sheryl lives in our marina, if they have room on the boat shell just wave you on board without buying a ticket. Ive been out with them numerous times.
