When at sea, pirates used special tools to navigate and get to islands and ports more then your average telescope. Also on hand minor weapons to use.
AstrolabeEditThis 16th century astrolabe is used to find their way across the great oceans of the world. Invented around the end of the 15th century, it enabled seamen to navigate by the sun and the North Star, measuring their altitude above the line of the horizon. The astrolabe and the compass were the source of main navigation for over 200 years.
Diptych DialEditThe truly amazing device, ? was created in Germany in the 17th century, served as kind of a compendium of instrument for calculating time & direction. The upper two leaves shows the times of day and planetary hours, as well as relative position of the planets. The lower leaf shows latitude measurments for Europe. A piece of string, known as "gnomon" stretched between the upper and lower leaf and was used to take measurments.
LodestoneEditSeamen used this when the compass was still under development they made it with pieces of natrual magnetic rock called Lodestone.When a needle was put against it,the needle became magnetized and could be used to steer by.Lodestones were valuable and were often incased in cases like in the picture to the right.
Pirates relied on the compass on long sea voyages and other navigational equitment to avoid getting lost. Alot of the time they were mounted on pivoting rings called gimbals, which left the needle free to be drawn toward the magnetic north.
The navigator could then estimate with surprising accuracy and longitude ( the direction of east and west ) and the distance traveled.
TelescopeEditThe telescope was invented in the early 17th century. After which it became a main tool of seamen and pirates everywhere. allowing the user to observe landmarks and islands to which a course could be steered, Of course telescopes were also useful for spotting enemy ships and bases. The nickname for the telescope was "bring 'em near"
