Which currents would help this explorer sail along the east coast of North America then return to Europe?

To sail along the east coast of North America, the explorer would benefit from the Gulf Stream, which flows northward along the eastern seaboard and provides favorable winds and warmer waters. For the return to Europe, the explorer could utilize the North Atlantic Drift, a continuation of the Gulf Stream that heads east across the Atlantic. Additionally, the prevailing westerly winds would aid in the return journey. Together, these currents and winds would facilitate efficient navigation between the two destinations.
