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.
Best Answer: I bake mine in a loaf pan so it catches the juices/fats that bake out of it. If you're going to use a baking sheet, make sure it has rim edges! I bake my 1 1/2 pound meatloaf for 1 1/2 hrs. at 350 F. You're probably fine with 1 hour at 350 F for 1 pound.Enjoy! I made meatloaf on Sat.eport Abuse. 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.
