When you do something for more than 40 years you get pretty good at it. We are pretty good at manufacturing our 21-foot Old Bay. This boat is our classic and the one that almost all other Duffy’s spring from. We’ve built thousands of 21’s over the last 45 years.

If you’ve ever rented a Duffy or been on one as part of a tour, you’ve more than likely been on an Old Bay. Our 21-foot boat is popular with both rental fleet and tour operators.

"On a winter evening, there are very few boats out which would make for a very romantic setting. We turned up the music, danced a little bit, and enjoyed time to chat. I'd highly recommend Duffy boats."
"Just bought my wife a Duffy last Sunday for her birthday. The experience was unforgetable. This has been something both my wife and I use every week."
