Nieuwkerk FamilyKnoep Nieuwkerk has been fishing since 1996. His boat, the Hanna Jo, is a 38' Novi boat and fishes out of Government Warf on the Kennebunk River in Maine. It's a family operation: Knoep is on the water year round, his wife, Lucinda, delivers the catch from the dock each morning to Portland, and their children are often found on the boat.
