THIS is who you want working on your boat! I have so much peace of mind after hiring Holdfast Marine to do battery replacement, electrical rewiring, and proper thru-hull grounding on my sailboat. Jon is such a pleasure to work with and his experience and professionalism are apparent in the work he does. He even takes the time to answer follow up questions I have once the work is done -- which is really helpful. Holdfast Marine is my go-to for getting the job done right and on time!

I had a wonderful experience when dealing with Jon from Holdfast Marine. He showed up on time to my boat (to both appointments), not knowing what he was getting himself into. My boat hadn’t run for a couple of years, so he began his diagnostic work. His meticulous analysis of my boat led to the correct diagnosis of a problem with the starter. He removed it and was able to replace a new one in my boat at my earliest convenience. Throughout both of our appointments, Jon was very helpful by telling me what he was doing and teaching me more about my boat as we went through the diagnosis process. Jon was very professional, friendly and highly skilled. I definitely recommend Holdfast Marine for any of your electronic or mechanical boat needs.

Jon is a fantastic mariner, and overall intelligent electrician. He’s the kind of person you want working on your boat. Top marks!

Very professional work, ABYC certified!

Jon does very clean work and has a tons of experience.
