Join the Europeans who led the way in search for new routes across the oceans. They were funded by kings & queens and motivated by the desire for wealth in the guise of spices. These were not easy voyages, lack of food & water plus bad weather led to sinking ships or ill sailors.
Possibly the best known is James Cook who would test the K1 (copy of the H4 sea watch) to establish longitude at sea. Also well known is Amerigo Vespucci, and while he did a lot of exploring of the South American coast, it is for the placing of his name on a map.
Would you be brave enough to travel days at sea with no idea of where land might be?
