My main quibble is not that it's too easy, but that most of the stuff is irrelevant to many(maybe a majority) of boaters. The home version of the test require some time and concentration, as someone above pointed out. It's baffling that there are 2 ways of passing---the quick way at the shows and the longer way at home. But relevancy? e.g. On most all inland lakes there are no marker buoys, questions about the min length of rodes to be carried on larger vessels etc.
Paul--I'm puzzled re your comments about canoes. No licence is req'd for those.
