Duffy 21 “Old Bay” Amply Blessed

There’s no better way to relax, unwind and connect with friends, family, clients or business associates than cruisin’ in a Duffy.

Harbor Crusing

For sunset happy hours, brunch on the bay, or afternoon outings with colleagues, cruise in comfort and style in the perfect craft for safe, reliable, sophisticated fun.

Party Time

No matter what you’re celebrating, do it on a Duffy—the perfect party boat for birthdays, anniversaries, club and association gatherings, and holiday revelry. Just add water, party guests, and festive fare and drink… and come prepared to have a great time!


Grab your honey, your favorite libation, a loaf of bread and pow! Climb on board a Duffy, turn on some tunes and watch the sunset as you reconnect with a favorite flame or significant other.
