The nautical star tattoo is the most masculine design amongst star tattoos. Nautical star tattoos are considered old school. In the early days of tattooing, they used to be popular amongst sailors, who had them for guidance and protection. Sailor Jerry is a famous tattoo artist from those days. The nautical star is a 5-pointed star, the points are split in half and filled with an alternating color (usually black-red or black-white), creating a 3d illusion.
Sailors used stars and the North Star (aka Polaris) for navigation, so it's not hard to see why so many of them have star tattoos. They function as a guide to get them back home safely. Soldiers have them for the same reason. Swallow tattoos also have a similar kind of nautical history.
Also today, people have star tattoos for similar reasons, you can rely on them when you are lost in your life, they are a light in the darkness.
