Whilst at first glance it seems ridiculous, it's a course suited to the demands of the industry.
In North Devon alone the Surf Industry is worth over £52 million. That industry needs the board designers and shapers, the store owners, etc.
The degree incorporates elements of Ocean Science, Business/Management, Meteorology, Physics, Human Biology, Ergonomics, Engineering, Physiology, Economics, International Relations.
So, while it may not be further maths, or chemistry, it's certainly not a pointless endeavour. My opinion is that these degrees should exist, but should perhaps be classified as something like a V.BSc (Vocational BSc)
