Good location at the entrance to Buzzards Bay. Facilities are fair, dinghy docks overcrowded, bathrooms/showers/laundry are adequate. Launch service responsive and reliable (CH9), excellent service department and ship's store. I've been mooring there for 20 years because it's equally convenient access either to the Vineyard or Newport, and seasonal prices are reasonable. Seldom spend the winters there because with a crane but no travel lift I'm required to unstep the mast. Westport harbor is great. Easy dinghy access to beaches near Horseneck Beach, good restaurant within walking distance, excellent upscale supermarket (Lee's) is a 4 mile Uber. Maybe they deliver...? Be prepared for the strong Westport River current. Channel shoaled last year to an unmarked, local knowledge nail biter, but for 2023 the new channel is well defined with lighted nun buoys (don't be distracted by the flashing reds if you approach from the sound after dark). A quaint, old school New England port, well worth a visit, not yet heavily trafficked, exploring the river and estuaries is great by paddle board, kayak, or fast dinghy.
My favorite spot on the Vineyard, so five stars no matter what. They raft up to four boats (always sailboats) on each of the two inside moorings. We've made some good friends that way, collaborating over fenders, springs and mooring lines, sharing or not sharing conversation and drinks. Sunsets seldom disappoint in Menemsha. Oh, the marina? Harbormaster's office, shopping, and two exceptional seafood stores/restaurants, public restrooms with pay showers, and a beach are all 1-3 minutes from the dinghy dock. Fuel/water dock accommodates one boat at a time and can be tricky in the current. Active fishing fleet only adds to the ambiance.
Avoid the insanity across the river, spend your transient night here. Well kept yard, docks in good repair, nice and much appreciated bathroom and shower facilities. In a quirky touch, there's a red British phone booth and a post box, if you have 10P.
