Method
Every sheet starts as a list of depths, not a drawing.
Survey before style
We row the water with a lead line and an echo sounder before a single line is inked. Depths come first; the drawing argues with them later.
Fewer marks, read faster
A harbour master should find the channel in two seconds. Anything that slows that down — decoration, a third colour, a clever font — is cut.
Names from the quay
Place names come from the people who fish there, spelled the way they say them, checked against the parish records.
“A good chart is mostly the things you were brave enough to leave out.”

Tell us where the water is.
We take on four commissions a year — harbour trusts, sailing clubs, and the occasional island that has never been drawn properly.
