"Excellent blend of theory and real-world experience"

The section on seamanship and ship handling stands out as one of the best written explanations I have encountered in print. Capt. B. Santhakumar clearly understands what mariners face at sea, and the writing never loses sight of practical reality. One star held back only because I would love more coverage on autonomy and future navigation technologies.
