Lack of Advanced Navigation Techniques: In the early days of exploration, sailors did not have access to precise navigation tools like compasses and accurate maps. They primarily relied on celestial observations and dead reckoning, which were susceptible to errors and could lead to detours or getting lost.
Unfamiliar and Vast Oceans: The oceans were largely unexplored, and the vastness and unfamiliarity of the open seas brought a sense of uncertainty and danger. Sailors were unaware of the currents, winds, and potential hazards, making it challenging to plan safe routes.
Small and Limited Ships: The ships used in early voyages were relatively small compared to modern vessels. They were often made of wood and had limited cargo capacity and maneuverability. These factors made them vulnerable to storms, strong winds, and rough seas.
Lack of Proper Provisions: Preserving food and water for long sea voyages was a significant challenge. The absence of refrigeration meant that fresh supplies quickly spoiled, leading to malnutrition, scurvy, and other health issues among sailors.
Diseases and Infections: Ships were often crowded, unsanitary, and humid environments, which facilitated the spread of diseases like yellow fever, smallpox, malaria, and dysentery. These illnesses could decimate crews and cause severe health problems during the journey.
Limited Knowledge of Oceanography and Weather Patterns: Sailors had limited understanding of ocean currents, winds, and weather patterns. This made it difficult to predict and navigate around storms and other adverse weather conditions, resulting in delays and increased risks.
Unforeseen Natural Phenomena: The oceans are home to various natural phenomena, including storms, icebergs, and fog, which could pose significant dangers to sailing vessels. These unpredictable occurrences could disrupt voyages and lead to loss of life and damage to ships.
Maritime Piracy and Hostile Encounters: Pirates and hostile encounters with indigenous populations added an element of danger and uncertainty during ocean voyages. Sailors had to be vigilant and ready to defend themselves against potential attacks.
Despite these challenges, the human desire for exploration and trade throughout history motivated people to overcome the arduousness of ocean voyages, pushing the boundaries of knowledge and contributing to the development of navigation, cartography, and shipbuilding technologies.
