Kayak racks I made with shelf brackets. Brackets are 11x14, if I remember correctly, and can be mounted either way, so that leaves a hole out at the end of the top one that I thought I would put a bungee through over to an eye screw mounted on the post (to secure the yak). Yaks sat so nicely that I decided I didn't need that. I cut up a noodle and slipped it over bracket for padding. Yes!
