GPS map coordinates on 1715 shipwrecks?

[ourhistory153]

Does anybody know if there is a index of GPS map coordinates of beach sites where
treasure has been found? Maybe the Cabin Wreck coordinates. Or just the McLarty
Museum would be a good start.

I started an index with my other historical interests.

WreckDiver1715,

Why is it when I convert these to decimal they seem to be wrong. This one, for instance, shows in the middle of land. 27.76667, -80.40639

What am I doing wrong?

Don't convert them!

They are displayed in hddd mm.mmm (heading minutes.minutes) SPRINGOF WHITBY shows on my GPS as N 27 48.200 / W080 24.700.

or if you convert to hddd mm.ss.s (heading.minutes.seconds.seconds) it would display as N 27 48.12.0 /W080 24.42.0

Hope that helps!

Tom

Did you see the shipwreck on the Map I posted here? It is called the Whisper Fir. Anybody know anything about that?

Also, there is a online mapping service where you can post the coordinates and a map will come up of that area. Anybody
know the URL for that?

I use Garmin's "GPS Maps of the World" software to build my maps.

It actually says "Whistle FIR" and I think it is some type of a marker connotation rather than a reference to the wreck just above it.
