Irwin Marine continues to grow nearing our 100th year in business we have added a second location in Alton and made some changes to our original Alton location’s role in our business.  We are proud to add a water location in Alton Bay combining the two locations functions to serve our customers better.  We have moved all sales operations to the new Alton Bay location and have made the original Alton location the service and storage center for our customers on the SE corner of the lake!
