This tape appears to have been made at least 15+ years ago. The referenced navigation texts by Mr. Gonder are no longer in print. Unfortunately, the approach is to recite rather than to teach. Complex subjects are covered in haste. No summaries are made for detailed subjects like lighting or signals. The only purpose this tape served was to convince me to allocate more preparation time for the test, which I appreciated. Recommend some of the newer versions by Magic Lamp's Safe Boating Series.
