I picked up cup holders at a Canadian Tire store here. They are hinged and when needed fold down and have an adjustable cup holder to fit a drink. I put 1 below my shifter/throttle controls. I asked my 1st mate where it was most convenient for him to have for either fishing from the bow seat or the rear casting platform. He said here and here and was very surprised when I took the drill out of bag, handed it to him and told him to mount them wherever he wanted. I paid something like 7 bucks each CDN. That gives me 5 cup holders on my 19 foot fish/ski rig. I like that they fold up and lock tight and out of the way when not in use. Came in black or white, I still have an extra in the package and will look tomorrow for the brand,
