Frank Connelly and Sue Polans live aboard a boat that is smaller than most homes, but that doesn't stop them from celebrating Christmas with a 7-foot-tall tree.

Frank Connelly walks back to Emma, the boat that he and his partner, Sue Polans, call home. Shrink-wrapped for the winter, the boat is docked at DiMillo's.

Tim and Kathy Reilley sit with their dog aboard their boat, Carina. The Reilleys live aboard the boat and spent last Christmas in Florida.

Cappy, Frank Connelly and Sue Polans' dog, sits on the boat they live aboard year-round.

Matt Wilkinson poses for a portrait in front of his sailboat Snowbound Evening at DiMillo's in Portland. Wilkinson is new to the dock but lives full time on his boat.

Christmas decorations adorn the inside of the power boat Emma.
