I was going to ask how you got on. I was busy from 10:30 onwards elsewhere, so no probs whatsover. If places like Portland are anything to go by, small groups of shears could as likely be Balearics in the middle of the day as anything it would seem.
I asked this a while back, even going into the harbourmsters in the high street. They did give me a printout with a position -
50 deg 06.04;'N, 004 deg 59.65'W
Which is absolutely useless for me! I was told eslewhere that it was 4 miles out, but it would be nice to know more precisely, plus of course is that from Falmouth harbour or the site it was towed from as opposed to Pendennis?
The above position should be possible to work out with the correct GPS gadgetry, or sea charts, I actually discussed this with the landlord this evening, so may be able to get somewhere hopefully.
Another useful possibility is a mobile phone app which identifies ships at sea - given the number in the bay if a distance is also included this could be interesting ...
