If you're lucky enough to own four surfboards and be embarking on a surf travel adventure, then you might want one of these. The Dakine World Traveller Coffin will make your quiver easy to lug around (it has wheels) and less likely to get trashed (generous foam padding). Available in sizes from 6'4" to 10'0" for £165.
