With full-color chart details and photos (both aerial and on-the-water), illustrated endsheets, and chapters on Nantucket piloting, weather, tides and currents, anchorage, history, and shoreside attractions, this book unites beauty and utility to an unusual degree. Yacht designer Alfie Sanford has been sailing around Nantucket all his life. When he tells us to tack over to starboard just past the green can marking the end of the second dry shoal entering Eel Point channel, do it. He's been there, and he knows.
