better pic of aforementioned seats
why anyone would pay 1000 quid for one I dont know ?
with all the engineering know how on this site, making a simple jockey seat with similar type suspension would be a doddle for someone
a simple design of a parallel hinging wishbone and a light suspension shock / spring unit would do the job
I am very surprised that nobody has not already started to produce such a simpler cheaper seat
It would appear a good solution to the age old bashing you experience in a speedboat or rib
Manos Another marketing opportunity for you !!!
(looking at the design below it would appear to hinge at the front bracket and move against the shock at rear, with a wishbone design the seat would move up and down in a level plane )
