Which outcome occurred when 18th-century navigators relied solely on dead reckoning during prolonged bad weather?

💡 Explanation

When dead reckoning was the only method, systematic errors accumulated because estimations of speed and direction without external references led to compounded inaccuracies. Therefore positional errors grew, rather than velocity errors being compensated improving chronometer accuracy or latitude, all of which necessitate other navigational principles.
