yup, kayakers do have a better water sense in a way, in a way that if they apply this stroke, they know the kayak will move more efficiently. so if u put 20 of these kayakers in a dragonboat, they can all apply this efficient stroke, therefore, enabling them to have an adv over dragonboaters. plus, endurance wise, they are definitely better. indeed, cross training to kayaking will help dragonboaters to increase paddling endurance. Cheers.
