Welcome to the new Irwin Marine of Alton Bay!

The team at the “Tip of the Bay” is excited to continue the tradition of personalized service started by Ernie Gillan Sr. over 30 years ago while joining forces with the largest and oldest full-service marina in New Hampshire, Irwin Marine.

The new location on Route 11 in Alton Bay (next to the bridge) is a full service facility offering new Larson sport boats, water sport towboats by Supra and Moomba. Our service department is open 7 days a week in-season and our parts department is fully stocked to ensure you won’t miss any time on the water with your family and friends.

New for the spring of 2015: our ship’s store will be expanded to carry more of the items you want to get the most out of your day on the lake. Towable tubes, wakeboards, wake surf gear and more will be on hand as well as stand up paddleboards by Riviera and canoes and kayaks from Old Town.

Stop by and see what’s new at Irwin Marine of Alton Bay.
