I know that these yachts (50-60') were imported from Taiwan into Indiana. As a Canadian, we pay 9% duty on any boats/yachts that are built outside of the US, however that may not apply if the boat has been restructured or modified to a certain extent in the US. I'm having trouble finding this information from US/Canada customs. Does anyone know more about what modifications if any were made after these boats were imported.
Try reaching out to a member of the Shaw family at Marlago boats in Indiana. They're the family behind the Jefferson brand.
