Hi Richard
Is sea-swimming also of interest (close linked to the island hoping)
If so this article might also be of interested
Bringsøe, H. 2001. Hav og hugorme. NHF, 44(2): 65-69.
(translated it would be: Sea and vipers) - it has a short english summary, which i might be able to scan to you if you like.
