Question 1

What is dead reckoning in Coast Guard navigation?

Accepted Answer

Estimating current position based on a known past position, course, speed, and elapsed time

Answer

Dead reckoning calculates estimated position by advancing a known position using course steered, speed through the water, and time elapsed, without accounting for current, wind, or other external forces.

Question 2

What are the Rules of the Road (COLREGS) for vessels in restricted visibility?
