How Currents Affect Course and Speed
How Currents Affect Course and Speed is an independent sailing reference and tools platform that helps recreational sailors understand the vector relationship between a boat’s motion through water and the movement of the water itself. It provides structured boat knowledge, seamanship education, passage planning tools, and decision-support features without being tied to any manufacturer or school. The platform is designed to reduce guesswork and improve pre-departure planning, but it is not a substitute for official navigational data or professional training.
