1. Sketch the
coastline (picture of coastal sketch—line drawing)
2. Draw
coastal profile of harbors, inc. hills, dunes, mountains. Image from Duarte Pacheo Periera’s De Esmeraldo Situ Orbis
3. Survey the length
of coastline visible from ship (Basel BW illustration (woodcut) showing
surveying from ship.
4. Note all the
hazards to ships including sandbars, submerged rocks, swamps. Side by side Iimages of hazards from Benincasa with modern nautical chart (US or Russian)
5. Note all rivers of
inlets visible from shipboard even if you do not land (potential future trading
location)
6. Note safe harbors
(shelter from storms, sufficient depth)
7. Compass angles for
sailing (compass drawing from a map)
8. Impact of rising sea levels on coast

Acquiring
information for a coastal sketch required ability to draw—both the shore and
the profile of the coast. It also demanded the ability to situate the
navigational hazards, and river/lagoon entrances precisely. Surveying ability
was required to measure the size of the stretch of coastline visible from the
ship.
