I have no commercial interest in this though as moderator of Willard Boat Owners, I have known the owner for over 20 years. She's located in Wisconsin. At 40 feet, she may be smaller than the other boats you're looking at, but these are incredible boats for a couple.
One of the last Willard 40s built. She's stabilized and I believe has been kept in a heated storage during winters. A gem of a fresh water trawler offered by a knowledgeable owner who has owned her since almost new in 1999.
If you pursue, tell Richard (owner) that Peter from WBO referred you. He's a great guy - he owned a W30 before Adria.
