Repair & Service

From minor repairs to major refits, from new boat gremlins to new mysteries on older boats, Zimmerman Marine has the knowledge and skills to take care of your boat. We don’t rent slips, pump gas, or sell shoes – we repair boats and our entire organization is focused on providing excellent service. We assign a service coordinator to each boat, so that you have one point of contact. Your service coordinator keeps you informed about the status of your boat and the projected costs, and whenever possible we quote firm prices. Whether you own a 17 foot center console, or a 70 foot trawler doesn’t matter to us – it’s how you care for your boat that determines if Zimmerman Marine is the boatyard for you.


ZMI has a rich tradition of exceptional woodworking. As custom boat builders, our craftsmen are continually challenged to hone and expand their skills.
