Hello,
First thing, i need to tell you that i'm not a professional, but i sort out how to pass that problem..

You get the coastline, bur you need the one without borders, i mean (1:2000000 or so) then change the name to get rid of .dat, then:
load coastNAME
plot (coast(:,1),coast(:,2));
fillseg (coast);
coast_new=join_cst(coast,.005)
fillseg (coast_new)

if you don't like it change the value in green... not too much you will see....

after that insert a couple of values on the right positions, trial and error.... i mean look for the first second third... NaN and add one line using values that give you one land/water difference that you like....

tomorrow I will attach the files...
good luck: R

I know about the arrows... it happen to me yesterday...but without the exact coordinates that you use for the coast (do u use coastline extractor, don't you??) i can not tell you where to exactly insert the numbers...
if you attach the file `coastline extractor` give you in matlab format, would be better so i tell you directly where to look......

Y try to do your example... you can download it and see that if you add two lines in the variable coast_new, one in line 43887 lat 39 lon 28 and other at line 61925 lat 32 lon 27.5 you can manage to get the disturbing lines out the middle part of your nice-coastline-draw... :P
hope it help: R
