I have been trying to find a vessel constructed by my Grandfather who was one of the Gustafson brothers who owned the Ludington Boat Company out of Ludington, Mi. My Grandfather and his brothers built fine wooden sailing vessels thew the 40's, 50's, and early 60's. I know they built a few H28's in their day and possibly other Herreshoff designs. They were sold around the Great Lakes region and may have ventured elsewhere. Any help would be appreciated. Thank you.
