The chart is very much in the style of other charts produced by Jeffreys at the time and indeed this chart adjoins with the northern boarder of Jeffreys' chart 'The Island of Cuba with part of the Bahama Banks and the Martyrs' (see Heritage Charts A504). This is the later, 1794, edition of the chart published in London by Laurie & Whittle.
Jefferys also includes on the chart a great deal of hydrographical information around the Florida Peninsular and around the Islands of the Bahamas. This includes soundings and channels. He also marks sandbanks, reefs currents, anchorages and includes 'rhumb' or 'loxodromic' lines (taken from an initial bearing it is a line on a sphere that cuts all meridians at the same angle. It is the path taken by a ship that maintains a constant compass direction). Such lines were only really useful in waters which were bounded by not too distant land fall as they did not take account of the curvature of the earth.
