Heritage-23 Mackinaw Modern Boat Specifications 

The Heritage 23 is a lugsail rigged, modernized Mackinaw boat.  Mackinaw boats are classified as schooners and also fit the historic definition of cutters.. They were developed in our region in the 1800's as fishing boats, cargo carriers and passenger haulers. Their size was typically bigger by about 1-1/2 times than the Heritage 23 displayed here and were normally gaff rigged..  A picture hanging in the Iosco County Building indicates that they were in common use on Tawas Bay.

THE  DESIGNERS

Historic Design: 

Mackinaw boats are historic vessels developed in the upper Great Lakes region.  They were the pick-up trucks of the 1800’s and were used as fishing boats as well as for the short-haul transportation of freight and people.  Said to be the merger of Native American canoe building skill and European carpentry skill, the Mackinaw boat was an important aspect of the cultural and economic heritage of this area.  Looking for a classic regional boat,  the Mackinaw boat design was chosen by Heritage Coast Sailing and Rowing. 

Recognizing the skill level of volunteer builders, the group commissioned design and construction updates in order to take advantage of modern methods of boat building using marine plywood and resins and to make building suitable for kit building.

A search for skilled individuals to generate safe updates that maintained authenticity lead to Hewes and Company of Maine and to Alec Jordan of Scotland and Richard Pierce of Scotland.  Computer designed sheet of kit parts.   The Mackinaw rowing version kit is sold by Hewes and Company (pdf price list).

Updated Version Designer:


Richard Pierce

Richard Pierce was selected to examine historic Mackinaw boats and update the design to take advantage of modern material and techniques.  

Richard was uniquely qualified to accomplish this because of his extensive background as a boat designer, a  boatbuilder, a builder of models for tank tests and as a skilled craftsman with Computer Assisted Design (CAD).  Richard’s firm, Franklin-Eldridge Boatbuilders in Windemere, England has built over 80 boats.
