You need to use the GSHHS coastline database which has continuous unbroken coastline segments. I always use version 1.2. There are much newer versions of this dataset, but I have not tested the extraction scripts with them. It comes in various resolutions. Then, I use the matlab/coastlines/get_coast.m from the ROMS matlab repository :arrow: https://www.myroms.org/svn/src/matlab to extract the appropriate application coastline file for SeaGrid.

The GSHHS version 1.2 (gshhs.tar.gz) can be downloaded from the :arrow: ROMS website.
