I stayed in Marina Park, which can be a challenge for a sailboat since you have to back in. But, the team was helpful. The location is great. The bathrooms are clean. Marina Slip 30 had no internet. None of the slips at the far end close to the Yacht Club have internet, and since Sag has little cell service in the summer, that can be a problem.
Low key, great and quiet location in sag, staff is great although not always around, needs to have internet for the price they charge.
It's always a pleasure to stay at Coecles Harbor. The docking team is friendly and helpful, and Shelter Island is a gem Also, if you have a problem to fix, they have a knowledgeable team that can help.
