I've taken a 22 and a 25 across from Grand Portage. If I remember you have about 26 miles to cross, so you are never more than 13 miles from land. I can't say that I've seen a 16' coming across, but I have seen some smaller fishing boats over there. Rather or not they crossed or came over on one of the larger commercial boats, I don't know. But if the water is calm, and a good forecast, I suppose you could. Is the 16 really any less seaworthy than a 22? Maybe Jay Green can answer. He has taken his 22 over from Houghton. It is a beautiful island to explore, and once you are over there, there are plenty of smaller bays and protected coves you can sit out weather in. Colby
