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: For that amount of meatloaf, I would cook it at 375 for about an hour to an hour and 15 minutes. I would cover it with foil, but it's not necessary. I've never cooked one in a loaf pan, but I don't think that would change the cooking time.Source(s): I make lots of meatloaf.aking time 350 degrees 1 hour for every 1 1/2 pound. I use 2 pounds of chuck and 1 pound of sausage in my meatloaf and I always bake it at 350 for at least 3 hours but like I recommend cover with foil until the last 15 mins.
