Fitted hull means the bare hull weight plus all the fittings Hobie adds internally/externally, not including seats, drives, paddles but includes drivewell plugs ...I think.
I weighed my ‘10 TI and posted details here
https://www.hobie.com/au/en/forums/view ... 71&t=53756My TI has a hull weight of 59kg, plus the 2 seats, drives and paddles for a kayak mode total of around 71kg.
The 2010-2014 TI models were much the same. In 2015 the TI hull had some minor hull changes like reverse bow and seatwell to accomodate the Vantage seats, with a slight increase in weight.
