Given a starting point from dead reckoning (calculations based on speed, time, and direction) or a sextant reading, you would track the boat's direction (with a compass) and speed (with a log) to continue to know the boat's position. Now, however, most mariners use a marine GPS chartplotter to navigate.ome handheld GPS units also are plotters, if they show the position of the boat on a chart. A GPS unit that provides the position only in longitude and latitude is not considered a plotter. For all types of plotters, the general principles are the same: 1  The screen shows a nautical chart.
Tips & Warnings. Small 1-pound meatloaves can be cooked at a lower temperature of 300 F to 325 F, if you prefer, for 10 to 12 minutes longer. This gentler cooking minimizes moisture loss as the meatloaf cooks, yielding a moister and juicier end result.

If you prefer, you can place the meatloaf to bake in a bain marie (water bath) ie: in a baking tin half filled with water.eat the oven to 180C/350F/Gas4.
