What is a log and line
A log and line measured a ship’s speed in knots. The line had knots in it at regular intervals and was tied around a log. A sailor would hold the line, throw the log overboard and measure the ship’s speed by how many knots passed through his hand in a given time (measured by an hourglass). The speed was recorded in the ship’s logbook.
What is a line and lead weight
To measure the depth of water, especially around a coast, a line and lead weight was used. The line was marked with depths and dropped into the water to ensure it was not too shallow for the ship.
Portolan chart ?
To navigate properly, new and more accurate maps were needed. Cartographers (people who draw maps) started using maps from Constantinople, which were far more detailed. The Portuguese developed portolan charts, which mapped harbours and coastlines more precisely, recording information like currents, tides and depth. As explorers returned from their voyages, the information they brought was used to update maps.
