Astrolabe. This is a term used for Portuguese ships that use triangular sails to sail against the wind.
How did ancient ships sail against the wind?
The air will blow on the sails, but friction against the water will mostly prevent the boat from traveling in that direction. The wind will be deflected off the sail at an angle parallel to the ship, where through simple Newtonian mechanics, imparts momentum that propels the ship forward.

The caravel (caravela in Spanish and Portuguese), was a type of medium-sized ship which, with its low draught and lateen or triangular sails, made it ideal for exploration from the 15th century onwards.
