Welcome to the classic ''Boathouse'' at 818 S. Main on the Centerville/Osterville line. This stunning waterfront property offers a lifestyle like no other. Located on the Bumps River this saltwater way joins the Centerville River & winds its way through East Bay & out to Nantucket Sound. Imagine waking up putting your paddleboards in the water for a leisurely glide over to your deeded private sandy beach for morning coffee; 250' of sand from river to sound. With over 60' of tie-up, return dockside & choose your boat for a 15-min. ride to Hyannis Port, Oyster Harbors or a little longer journey to the Vineyard. Enjoy the remarkable sunsets as you fish for schoolies from the dock. The home itself is most charming with renovations incorporating many features of the original boathouse. The versatile floor plan allows for a 1st floor primary BR. Upstairs is a private suite w/a Juliet balcony offering panoramic views. Come visit this unique property, in a setting that can never be duplicated.
