ENC charts often look fairly strange to people not used to them, since they are vector-based, rather than raster-based maps. At low magnification factors, the detail on them will often be determined by the software setup rather than what data is actually there.

The raster charts that cam is talking about are essentially scanned versions of the standard charts. ENCs are very different, as the data in them is not really graphical, but actually stored in a database format of a sort.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
