Hi and good evening, 

Anyone knows how to reproduce the concentric shoreline effect in affinity designer?

Pretty much exactly the same way. Start w. the shoreline line. Duplicate, and make the stroke bigger. Repeat as you like. Expand. Make fill none, and stroke minimal. Break the curves' end nodes, deleted the inland parts. Kinda tedious, but nothin' hard.

Hi @gdenby, I ended up with this:

Hi again, ivanozzo,

Glad its working for you.

This topic has come up a few times. Your post got me going, and I've just blown several hours over the last few days doing the same on an imaginary place map. I can see why there are people who work on story book antique looking maps.

Update: Spacing waterlines (credits: John Nelson - https://www.esri.com/arcgis-blog/products/analytics/analytics/water-lines-they-need-some-space/ ).

Take a look at John's spreadsheet:

https://docs.google.com/spreadsheets/d/1jeexb_WT3Q0S_upAPInUzO6VlEOcpZo3BHRkpXv-_YY/htmlview

Ex: spacing lines of 130%

1° line: 5pt

2° line: 5pt + (5pt  * 130%) = 11.5 pt

3° line: 5pt + (11.5pt * 130%) = 19.95 pt

...

...

And so on.
