Improved navigation capabilities enabled longer voyages across oceans with more accuracy leading generally towards expansion into new territories by sea through exploration or conquest, often compounding other effects such as colonization or trade network expansion.

The invention of cannons allowed Europeans better defense against pirates at sea, increasing overall safety and reducing losses incurred from piracy-related activities, however not specifically enhancing exploratory efforts except when used militarily against other nations’ vessels, potentially blocking routes or resources desired by Europeans.

Caravels made inland river travel faster, spurring economic growth along waterways, but having less direct impact on oceanic exploration, despite some limited use navigating larger rivers or near coastlines where appropriate conditions existed.

Inclusion of galleons in the fleet reduced the cost per shipment, allowing merchants to ship goods cheaper, eventually leading to an overall decrease in the price of certain commodities, however not necessarily tied directly to increases in exploration itself, though it may have facilitated greater volumes being moved over distances previously considered too risky or expensive to undertake without these savings.
