Always first rate. Well kept moorings, helpful staff and a pump out boat. Only slight negatives are exposure to northeast, which is generally where tougher storms blow from, and the launch is a bit pricey at $5 pp each way. The dinghy dock is getting more and more crowded every year. Needs to be expanded, but it probably belongs to the town, not the mooring owners.
I love Edgartown Harbor. The mooring field is well protected and the harbor master is very helpful and professional. The dinghy dock is starting to get ridiculous. It's always had the deserved rep of being three deep at times. It's now all the time. Boaters come and spend a ton of money in town, which must generate local revenue. They really need a larger or additional dinghy dock, even if it's a bit further from town.
Perfect downtown location. Pubs, restaurants, street performers, historical sites, the commons, etc. Everything within walking distance, except perhaps a grocery store. Uber/Lyft is readily available tho. It gets a little choppy during the day, not bad, but calm at night. Staff was very helpful.
