Today marks the beginning of my voyage into the unknown, driven by an insatiable thirst for discovery. As the ship's sails unfurl, leaving my family behind, a bittersweet ache settles in my heart. I’m anxious yet exhilarated, surrounded by the hum of anticipation and the sound of waves crashing against the hull. My musings drift to the advanced tools I carry: an astrolabe to chart the stars, a compass to guide me through uncharted waters, and the sturdy caravel ready to brave the elements. I can only wonder what secrets await across the horizon.

CARAVEL • Light, fast sailing ship • Steered with rudder at stern • Lateen sails • Triangular • Catch wind from any direction
WOODEN BARREL • Store drinking water, food, and supplies • Made of staves bound with iron or wooden hoops • Staves bowed to make barrels wider in middle • Allowed barrels to expand as filled with goods
