"The most complete seafaring guide I have read"
After many years at sea, From Sextants to Satellites is the book I wish I had when I started. It connects scientific knowledge with practical seamanship in a way no other text has managed. The chapters on the human element and ocean understanding are particularly outstanding — essential reading for any serious mariner.
★★★★★

"Required reading at our maritime institute"
We have adopted From Sextants to Satellites as a recommended reference for our navigation and seamanship programmes. Capt. B. Santhakumar's ability to blend scientific rigour with practical experience makes this book uniquely valuable — students find it far more accessible than traditional textbooks, without sacrificing depth.
★★★★★
Verified Purchase
"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.
