Navagational Problem

[wreckee]

I'm looking at a map dated 1863 . The bearings for a wreck are North by West from this rock ( ok no problem ) . But the second cross bearing is NE by E half E . Does anyone know how many degrees this is form True north . I will adjust for magnetic north in that year Cheers Nick

Get yourself a copy of an old marine compass rose. The 1/2 points will be
clearly indicated all the way around the card. Just remember that compass
points are not the same as degrees.

Thanks for you reply but just can't understand the E half E bit.

Sorry OK OK I understand now. Thanks !

Nick:

NE by E half E:
NE by E is 56 degrees less 15 minutes
NE by E half E might then be 56 degrees less 15 minutes less another 7.5 minutes OR 56 degrees less 22.5 minutes.

I sent Don (who anwsered above) a email to look at a marine rose . On this is looks like 61 Degrees ? The link is http://www.stormy.ca/marine/compass_rose.html
Yes /no ?

The correct answer to NE by E 1/2E is = 61 degrees 52 minutes and 30 seconds.
