We talk a lot about boats, their related systems and the techniques to use them to sail the best we can. However, it’s also very important to have a solid understanding of the elements we all find ourselves in whenever we untie and cast off. Take a crack at this quiz that focuses on just that – tides, fog, currents… that kind of stuff. This quiz is created from the information found in ASA’s 104 Bareboat Cruising Made Easy textbook. Good luck!
