Win a set of tapered Cat Battens at the RYA dinghy show.

Visit the UK Catamaran racing Association Stand (UKCRA) at the RYA Dinghy Show and enter the F18 class competition to win a set of Cat Battens.

For more information visit UKCRA stand, C4, talk with the F18, enter the competition and test out the product.
