New product for us: Paddle parks by Steve!
 
These are in stock and I'll be ordering more.
 
From Whetman's site:
Secure spare paddle shafts on the bow of a sea kayak for simple quick access & simple to repack on the water.
Easy velcro wrap installation
To install
Wrap the webbing round the decklines and secure with velcro underneath. Use the red cord to tie off the cuff to either a deck mount or deckline to prevent it travelling along the deckline.
Sizes
One size fits all paddles including push button and metal lever lock
and the larger nylon lever lock fitted on some paddles.
