The lunar was taken in the very rolly anchorage behind the reef. Not
open ocean, but definitely a lot of motion.  The moon happened to be
nearing its highest point, providing several challenges.  It was very

difficult to get the sun over to the moon, and the high altitude made
for a very awkward posture when I did. This sight was a prolonged
struggle; I tried several postures but found nothing comfortable.
...

All in all, I am pleased with how well it came out given
the difficulties.

It took longer to read the message. Nothing about sails (well, Arthur was at anchor at the time) and this seems to have been the conclusion:
"

I felt I got a good look at a couple
of the contacts but struggled with the others.  The graph of the
observations is more consistent than I would have guessed although I ended
up pretty far off.  I would guess that had I worked the longitude as I did

with the first set, I'd be off by over 80 miles. Practice, practice,
practice... I suppose I'll just have to spend more time in the
Caribbean!
