It's good that boaters are familiar with all the information your course provides. Having onboard a study guide for reference with ready checklists should be mandatory. As a commercial pilot, I cannot overemphasize the value of checklists. However, for practical purposes, with your current study format, the student suffers from information overload and the sample test questions are occasionally irrelevant. Eg; Is it important for the boater to know under which body of law [criminal code or some other] he/she is to be charged or simply that an act is illegal. Or, what the first sign of "cold water shock" is ["deep and sudden gasp etc.] rather than the clinical term for this symptom [cold shock]. Wrong answers should be identified to ensure future compliance. With this in mind, your training should be simplified and test questions should concentrate on what the immediate action should be taken to avoid catastrophe rather than identifying the nomenclature of such maladies and their subsequent phases. Non essential information should italicized or placed in an addendum. An online source to download and print checklists for individual crafts may prove an complementary aid to waterway safety.
