Boat Building

Building hand-crafted boats since 1981.

Zimmerman Marine has been building custom and semi-custom yachts for almost thirty years. Our Downeast style cruising powerboats have proven themselves from the Bahamas to Nova Scotia, in the Great Lakes, the Pacific Northwest, and up to Alaska. These are exceptionally capable boats – able to go out in almost any weather and return unscathed. Owners often report that the boat can take considerably more than they can. That’s what you would expect from a hull form that has evolved through a hundred years of commercial fishing off the coast of Maine. Don’t let her handsome lines fool you – these are workboat hulls, bred to work offshore, year round, in the worst weather. The seaworthiness of her Downeast brethren is legendary.

The Z31 is a small sister to our successful Z36 design. Both boats were designed by Spencer Lincoln based on working Downeast lobster boats. The 31 is intended as a weekender and as a boat capable of more extended cruises.


Our proven and popular Z36 has been redesigned by Spencer Lincoln as a 38. The Z38 features the same layout concept as our Zimmerman 36, but added length, more freeboard, and a more efficient hull.


The Z46, built on the time tested Jarvis Newman hull, is designed and built for extended coastal cruising in comfort and safety. Comfortable at 8 or 18 knots, the 46 can cover ground quickly when needed. Her sweeping sheer line and handsome bow will turn heads.

In addition to our line of performance cruising powerboats, ZMI builds one-off custom yachts. We have built custom sail and powerboats, from 16' to 56', in cold-molded wood construction, and also in composites.
