Irwin World · Since 1919

One hundred years, one family of boaters.

Jim Irwin opened his doors at Weirs Beach in 1919, and for the better part of a century Irwin Marine was the nation's longest-running Chris-Craft dealer. Four generations later, we're still on the same shore — selling, servicing and storing the finest boats on Lake Winnipesaukee.

Today Irwin Marine operates full-service marinas across New Hampshire's Lakes Region, carrying the century-old name forward under Resilient Marinas.
