Wildly overpriced for what you get. When we arrived, hailed to ask how to find our assigned mooring; no response. Called by phone instead; person answering phone didn't know, and there was no one else available. Included launch was not running (it's available 7 days a week, unless it's the dock person's day off, or he's not in). Free restroom in the store was disgustingly dirty; another restroom and shower in the adjacent building cost $5 per use. $2 charge to fill with water at the fuel dock. $5 per bag to drop off garbage.
Assuming 2 people on the boat want to shower once a day and use no other services, that's $50/day total. Compare the closest Dockwa-listed marina, Tenants Harbor Boat Yard: $87.50 per day (for our 35-ft boat) includes showers, clean restrooms, trash disposal, water tank fill. And that's for a dock, with helpful staff. Or $30 for a mooring, which includes launch, restrooms, showers, garbage, water.
A pity. We've wanted to stay in Port Clyde for a while, and it is a beautiful spot where we had a restful night. But we won't be back.
