A Port Washington houseboat that comes complete with a rooftop deck is on the market for $128,000.

The 1,100-square-foot boat was built in 1990 and has three bedrooms and one bathroom, says listing agent Debra O'Brien of Harding Real Estate Inc.

It's situated in Manhasset Bay.

"It has expanded panoramic views of Manhasset Bay, and it's in a protected inlet," O'Brien says.

The boat doesn't have boating rights or an engine, but it stays at the marina with a slip fee of just under $800 a month.

"You can take a water taxi over to the main town dock, and you can drive into the marina and park your car there before you get onto the houseboat," O'Brien says.
