My dear friend is a seamen of many years. I gifted him with some charts but needed so much help in finding and ordering them. ANS personnel were exceptionally helpful and understanding. Really, I knew very little, and they were just so patient. The fried who teaches and certifies for navigation was so pleased with the choice of charts, and the up to date accuracy. He is well aware oft he virtual chart world, but so loved these water proof charts. I received more credit than I deserved. ANS personnel did it all.
