Watch relative bearings change, predict crossing situations, plot offshore fixes with a 3 arm protractor, or check your compass by sun or stars. These are some of the things you can do with a pelorus. Large ships have permanently mounted peloruses, or some that can be mounted in deck shoes. On a smaller scale, these portable peloruses will give you many of the same benefits. A compass adjuster will find this a very nice instrument when calling on an assignment. The Shoe Mounted Pelorus comes with a deck shoe that can be affixed with two screws at a desired location where bearings may be easily taken. The pelorus can be taken from its storage box and be quickly mounted on the shoe. After use it can be returned to its box, or left out for later use. Storage box size is 9.75″ square x 5.75″ high, and is finished in natural wood tones.
The Boxed Pelorus is stored in its plywood box by resting on two lower gimbals. For operational use, the pelorus is raised to engage two upper gimbals in the box. The plywood box size is 8.25 ” square x 7.25 ” high and is finished in natural wood tones.
Both peloruses have a gimbaled bearing card which is 5 inches in diameter, and is marked in one degree increments. A sun shadow vane may be used for checking the ship’s compass. The heading indicator and sighting vanes may be locked independently of each other. The gimbals are weighted for stability, and overall construction is of metal and plastic.
The Boxed Pelorus is quite nice looking in its box. Apart from its functional attributes, it would be well suited as a marine artifact in a den or office. SW 5 lbs
