We have received many questions from curious customers who want to know if they can fit the new CT Vantage seat (introduced in 2015 models) into earlier model Hobie kayak hulls. We regret to inform you that no, this cannot be done, as the hull had to be remolded to suit. This is a shame (because we would have sold thousands of them if they were retrofittable) but understandable, given the design challenges of fitting a suspended seat into a kayak without compromising stability
