Got mine at West Marine over the summer, they were on sale I think for $39 each? 8.5" x 25" I think. The prices of the holders are crazy, so I bought a rubbermade tub at the dollar store and put it in the engine compartment with some holes drilled in the bottom to let water out. I store 5 fenders, 2 anchors and all my lines in it, and was something like $10. I have seen some pics somewhere that some guy made his own holders out of 10" PVC pipe and drilled some holes in it and painted them, mounted to the back of the rear seat. They looked pretty cool!!
