Nate Frederickson – President & Naval Architect, P.E.

Nate grew up in New England, where he became excited about boating at an early age spending time aboard a friend’s C&C 30, racing sailboats, and learning to windsurf and water ski. The allure of the waterfront led Nate to pursue an education at Webb Institute, where he earned a degree in Naval Architecture and Marine Engineering in 1996.

Following college Nate ventured to the Pacific Northwest where he cut his teeth developing and testing hull forms for planing powerboats, and later branched out to become involved in a wide variety of projects including design and construction of towing vessels, megayachts & other pleasure craft, long range patrol craft, barges, and passenger & fishing vessels.

Nate is a SNAME member who has held a Professional Engineering (P.E.) license since 2006 and is licensed in Washington, Oregon, and California. He has been self employed for a significant portion of his 20+ year career and founded Impact in 2017.

In his free time Nate enjoys spending time with his wife & daughter, skiing, cycling, camping, paddleboarding, admiring the northwest’s remaining old growth forests, and spending time in the mountains.
