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.
I line a rimmed baking sheet with tin foil, place the meatloaf (in a loaf shape) on the foil in the middle of the pan, and cook at 350 degrees for 35 minutes. Although the loaf pan provides a nice shape, the only place for the fat to go is to be reabsorbed into the meat.eport Abuse. I usually cook a 1 lb meatloaf for an hour on 350. Pour the tomato sauce/ketchup topping on and bake for 10 more minutes, and the let sit to cool. Either will work, when I didn't have a loaf pan, I would use a 9x13 pan line in foil and shape into loaf form.
