Whats the difference between a 12 or 14 ft tinny, or even a 18ft when crap happens? I was out in my 14ft sylvan tiller one summer morning. Calm, as calm can be. 4 hours later,east blows up and Im at the boat launch waiting to get out, along with 5 other boats. With 4-5 foot rollers that came up in 5 minutes, It got to the point, I was not waiting no more and just drove the boat onto the cement ramp. Boat got swamped, but was on land. Just bailed it out and loaded it on the trailer. I would say, I was smart and lucky I didnt get flipped waiting. It was me or the tinny. We both made it.
