Early explorers used ships as their exploration vehicles. Both polar ocean waters are filled with icebergs and sailing in them is not only dangerous but extremely cold. Until the technology -- reinforced hulls, for example -- supported expeditions into these extreme situations, Antarctica could not reached.
The logistics of sailing into uncharted, iceberg-filled waters is daunting, because the ship could be pierced by an iceberg and the temperatures are so low that all would perish in the cold.
Until ships could be reinforced and crews prepared for extreme cold weather, exploration of the southern-most continent was simply not practical.
