Boatyard Services

Hauling & Storage

Niemiec Marine has a 5-acre facility capable of hauling and storing up to 200 yachts ranging in size up to 70′ in length or 60 tons in weight. Our yard is locked at night and is under 24 hour recorded video surveillance in order to protect your investment. We provide the cleanest and most organized facility in the area. Our boats are spaced with adequate room around each boat to wax, wash and service each boat. We do not stack boats two, three and four deep like many other yards. Come by and visit our yard.

Mobile Services

Niemiec Marine, Inc. offers mobile mechanical service for routine maintenance and problems that may arise during the season. We have a fleet of on-road service vehicles equipped with tools and parts to service and support our engine lines: Cummins, Yanmar, Volvo Penta, Westerbeke, Crusader, Universal, and Phasor.

Electrical Repair

Electrical work can be tedious and overwhelming. Niemiec Marine has service staff with the experience and patience to perform both simple and extensive electrical repair and rewiring. We provide proper labels and diagrams when wiring a new component or system on a boat in order to allow another service technician or the boat owner to troubleshoot problems years down the road with ease. When running a single new wire or completely rewiring a vessel, our electricians make sure to use adequate wire size and heat shrink and solder every terminal end. We do not use crimp on connectors — these fail over time.

Fiberglass & Painting

The fiberglass and painting technicians at Niemiec Marine are highly skilled individuals. These services are available for both structural and cosmetic work. We provide gelcoat and fiberglass repair and well as painting and gelcoat refinishing. In addition, Niemiec Marine specializes in grounding damage repairs. We focus on making your boat structurally sound, safe and back to factory finish standards.
