I found a blue and white version at last but it is a bit tatty. The yellow roof rack does need to have the kayak in it too. The rack is fitted through four holes drilled in the roof so it needs to stay there and there's not a great deal we can do other than fit some vinyl to cover the holes perhaps! So it is pretty clear now that all in this colour variation will have derived from the Gift Set with the trailer, kayak and rider.
