⚓️ Exciting Updates at Grafton Harbor⚓️

Hello, I’m Ashley Sievers, the new Marina Manager at Grafton Harbor. I’m looking forward to another great boating season ahead.

We are currently in a transition period with the new owners of New Haven Marina, and we truly appreciate your patience as we finalize details and prepare for the upcoming season.

Updates on slip availability, boat rentals, and the tour boat will be coming soon. As information becomes available, it will be shared right here so stay tuned!

If you have any questions, please message us on the Grafton Harbor page. We’re happy to help! This page will be closing as of February 1st so be sure to follow our GH page.

Thank you for your patience and support—we’re looking forward to a fantastic season on the water!
