There are salty New England seaside getaways, and then there’s Captain Jack’s Wharf. Located in Provincetown’s West End, it was built at the turn of the last century for fishermen to store their bait and tackle and quickly became an artist hangout. The owners, who purchased the property six years ago, left the house mostly as they found it; they removed the layers of paint that hid the original floors in the open living room and redid the kitchen and bathroom. The furnishings are spare but comfortable; the ’40s-era rattan sofa complements the outdoor furniture on the deck beyond. It’s here that they spend most of their time: where looking out on Cape Cod Bay toward the Long Point lighthouse can be enough activity for the day.
