This thwart you seek. What type are you requiring……that is how does it attach to the tubes……okay over canvas straps or slide type as in the more recent Seago Dinghy’s?
I have one from an old Waveline 265 that died and had to go, but for some reason the seats still in my garage.
My dingy is a Bombard (Zodiac) and has attachment points on the floor. Will yours work with this? Or maybe I can adapt what you have. Thanks for your quick reply.
