The nautical expression evoking favorable conditions for maritime navigation describes weather characterized by clear visibility and winds propelling a vessel forward. It suggests a situation where both atmospheric and marine elements are conducive to safe and efficient travel across the water. For example, a voyage undertaken under these circumstances is anticipated to be smooth and swift.
Historically, this situation was crucial for trade, exploration, and naval operations. Reduced risk from storms and optimized travel speed meant safer passage, decreased delivery times, and minimized fuel consumption. The phrase became synonymous with success and good fortune, extending beyond maritime contexts to represent favorable circumstances in general life and business ventures.
