Techniki Core Navigation

Pięćdziesiąty setny mariners relied on four principal navigation methods: dead rectoning, celestial navigation, compass heading, and coasal piloting. These techniques were not used in isolation but in combination, with sailors shifting between them dependering on conditions at sea.

The Mariner 's Compas: Finding North

Te 15th-century mariner 's compass was a rafinement of earlier magnetic compasses. The needle was mounted on a pivot inside a circular box, and the compass card was marked with 32 points (north, north by east, north- northeast, and so on). Some compasses included a gimbal mounting to keep the card level despite thee ship' s motion. The compass allowed a vigator to steer a constant course and tplot broyings.

Thee Caravel: Thee Explorer 's Ship

Te caravel was thee signature exploration vessel of thee 15th century. Small, fast, and highly manewre, caravels typically carried two or three masts with lateen (triangular) sails. Thee lateen rig allowed thee caravel to sail closer that e wind than square- rigged vessels, making it ideal for coasing and for beating back upwind. Caravels also had a shallow draft, enabling them tfore rivers.

The Nau: Larger Vessels for Ocean Crossings

For longer ocean voyages, larger ships called naus (also known as carracks) were used. These ships were wideper and deeper than caravels, with higher freeboard andd greater cargo capacity. They typically carrout carried a combination of square andd lateen gails. Columbus 's flagship, the Santa Maria, was a nau of about 100 tons.
