Balboa 27 Chula Vista
Does anyone know where to get (other than the obvious source) the dimensions for the cushions on a 1979 Balboa? We're off to the fabric store and the boat is out reach for the measurements. I'm struggling to find anything online. We're just looking for a rough estimate on how much material to purchase.

Thanks for any help!
