Our Consultants
The World’s Most Trusted Team of Marine Consultants
On June 27, 2020, we lost our President and co-founder, James "Pritch" Pritchard. Pritch worked nearly 40 years in the marine industry and in 2009, followed his lifelong dream to establish North American Marine Consultants, LLC with partner Keith Weber, and was proud to watch that dream grow over the years.
Pritch was more than a boss, more than a co-worker; he was a beloved friend, father and mentor, and his loss is felt profoundly within our company and throughout the marine industry. We will miss him greatly, and will continually strive to honor his legacy by nurturing his dream according to his principles and vision.
