Second, it must be remembered that the bearing of any object obtained from the pelorus is the bearing _by compass_. ❋ Ernest Gallaudet Draper (1919)
Two pelorus repeaters swung to point a few degrees right of course. ❋ Richard Bach (2002)
Light clusters, clear, deep, on the face of the radio gear ... fans up softly off the dial of the pelorus ... spills out portholes onto the white river. ❋ Pynchon, Thomas (1978)
The center line of the pelorus should also be directly over the keel line of the ship. ❋ Ernest Gallaudet Draper (1919)
In other words, if the ship is heading NW, the pelorus must be set with the NW point on the lubber line when the bearing is taken of any object. ❋ Ernest Gallaudet Draper (1919)
The easiest and most accurate way to find the error of your compass is, first, to find the bearing of the sun by your pelorus. ❋ Ernest Gallaudet Draper (1919)
All being ready, secure the lubber's point of the pelorus at North and clamp the sight vane to the sun's magnetic bearing at the time you have figured to take the first heading. ❋ Ernest Gallaudet Draper (1919)
If, now, the compass were correct it would agree with the pelorus in showing the ship's head to be North. ❋ Ernest Gallaudet Draper (1919)
For that reason, it is wise to steam the ship completely around, steadying on every fifteen degrees by pelorus to determine and keep a record of remaining errors. ❋ Ernest Gallaudet Draper (1919)
As soon as possible after anchoring secure your bearings by pelorus and have them checked up by the quartermaster at regular intervals. ❋ Ernest Gallaudet Draper (1919)
Starboard or port your helm until at the time calculated the reflection of the sight vane on the pelorus dial cuts on the proper magnetic bearing. ❋ Ernest Gallaudet Draper (1919)
Have another officer who is thoroughly familiar with the pelorus stand by it as the ship is swung. ❋ Ernest Gallaudet Draper (1919)
In other words, it is just as though you took the compass out of its place in the pilot house, or wherever it is regularly situated, put it down where the pelorus is, and took a bearing from it of any object desired. ❋ Ernest Gallaudet Draper (1919)
If you set your pelorus, so that it will exactly coincide with the course you are steaming as shown by the compass in your chart house and then get a bearing of the sun by noting where the shadow from the pelorus vane cuts the circumference, this bearing will be the bearing of the sun by compass. ❋ Ernest Gallaudet Draper (1919)
First, that when the bearing is taken, the exact heading, as shown by the ship's compass, is the heading shown by the pelorus. ❋ Ernest Gallaudet Draper (1919)
Steady the ship on this heading until the shadow from the pelorus vane at the proper L.A.T. cuts the circumference of the pelorus dial at the proper magnetic bearing. ❋ Ernest Gallaudet Draper (1919)
These bearings will be secured in the best way by the use of your pelorus. ❋ Ernest Gallaudet Draper (1919)
If there is any Deviation on this heading, adjust the cast iron cylinders (called Quadrantal Correctors), which are on each side of the compass bowl, by moving them toward or away from the compass until the ship's head by compass is North-east at the proper time and bearing by pelorus. ❋ Ernest Gallaudet Draper (1919)
In taking a bearing by pelorus, two facts must be kept in mind. ❋ Ernest Gallaudet Draper (1919)
"Better use the pelorus and be careful about West Chop's bearing after we pass her, Mr. Bangs," Captain Mayo warned his first mate. ❋ Holman Day (1900)
