Finally here, to Ken's mention of megohm tests for boats. Again, for those of you not familiar with such testing, this type of test is used to test the integrity of electrical insulation and involves shooting a pretty high voltage through the system and determining if there are any breakdowns in electrical resistance or insulation that could cause a problem. In commercial boating environments, this procedure is actually a requirement as part of periodic inspections. It is really quite an involved procedure to perform a comprehensive megohm test on a modern boat's electrical system. Statistically, I can tell you that the number of system failures like the one described in "To Bond or Not to Bond" is so small, that in spite of the severity of that situation, the number of actual incidents like it in a given year are so small, I could never sell the concept of a required megohm test or cathodic protection level test to the committee that governs these things. Plain and simply, there is not enough of a demonstrated needs for such tests.
