Just an FYI, I have seen this boat many times as I believe it is docked at the marina next to me, Aspasia in South Portland. I have always admired it, and day-dreamed that I might be able to buy it and remove the tower. Good luck with the sale.
Yes it is the old Aye Roller. I have actually owned both of the Aye Rollers at different times. The Duffy is now a working lobster boat in Cundys Harbor and the Libby is used as a charter boat out of South Portland.
