DSK,

You don't have to sail the Longitude, you just need to know the local
noon hour. Fifteen minutes will put you 60 miles one way or the other.
Still within broadcast range of the Island.

By the way Doug, the Sun appears about one degree higher in the sky
about every 4th day (91.25/23.5=3.88 days per degree) if you don't have
an almanac.

A fist, with the tip of the thumb folded into the fingers, held at arms
length is 10 degree. 2 degrees per knuckle. 1 degree from the top of the
knuckle to the valley between. This will give you a sun sight within
sixty miles, within broadcast range of the island, if you don't have a
sextant or batteries for your GPS

Now, if my old 77 yr brain remembers right Montauk Point is pretty close
to 41 degrees Lat & 72 Lon ( 4 fists & 1/2
knuckle )and four and three quarters later than GMT

Bermuda is about four and a quarters later than GMT and about 3 fists
and 1/2 knuckle Sun Sight plus one degree for every day past March 21,
subtract a degree for four days to go to Mar. 21

Listen for the Broadcast from the Island, you can't miss it.

Have a great trip and enjoy.

Ole Thom
