Oh yes - I love sailing and photography but photography is a relaitvely new hobby, so I'm only just starting to combine the two. A series of pics I did of the local lightweight sharpies in action last summer can be found here: http://members.iinet.net.au/~roller/
I used HP5 fo rthat but when the sailing season starts again, I think I won't have any problems using slower film - either sensia or FP4 which should make for better pics I reckon.
Cheers!
