Inno Kayak Rack System $99.00
 

IMO the best lockable system. Used one season and had to quit due to sea sickness and choosing not to continue. Tried a few other methods but whis was by far the most simple and secure.

Amazon sells for $198. Save $100 and buy mine.

Here is a link to my CL ad to see a photo of everything, including two sets of keys.
