This Westhampton Beach Contemporary, listed for $4.2 million, was designed to make you feel like you're on a boat, says listing agent Ellen Berkowitz of The Real Estate Store.

There are porthole windows in the master bedroom and curved glass walls etched with wave designs in the master bath. The master suite also features a fireplace and private balcony with unobstructed views of Moneybogue Bay.

That's one of the breathtaking things about the 3.3-acre property, Berkowitz says, adding, "there's nothing between you and the bay but natural vegetation."

The 1996 home has five bedrooms with four bathrooms and a half-bath, an eat-in kitchen, media room and combination living room-dining room with a fireplace. The on-the-water feel continues outside the house, where there are multiple decks, a new pool with an outdoor shower, a private boardwalk and floating dock. The home comes with beach rights, and Berkowitz says the location is key -- it's just a short walk to town or to those sandy shores.

Berkowitz is listing the property with Real Estate Store's Gary Knotoff.
