I am interested in the Whitehall 17' rowboat, but specifically I want to know if it is possible to use the sailing configuration and have one or two oarsmen rowing at the same time? I would like to use it for ocean sailing to and from Catalina Island and that is about a 21 mile trip at the closest point. I do not want to use a motor so when the wind is missing it would be nice to be able to row, or actually row while under sail if the wind is light.
