Judging exactly what is 150ft!

Many of us have driven water skiier's or pulled a tuber

Another way to look at it and judge, which is the way I was taught and currently teach my kids -- maintain (at least) two ski-line lenghts from another craft or object and you'll be fine. Is this again subjective - of course -- but 9 out of 10 times MP is not measuring to the "inches" (barring a few Rambo's out there). The majority of the issues, but certainly not all, come when powering up after a NWZ --- especially the Wiers chanel - eithor side! Think of how many times someone has come right up your stern and flew off leaving a NWZ as opposed to "open water" issues. And I am NOT here to say open water issues don't occur .... their simply rarer.

With regard to posting the rule or any other rule at ramps or wherever ....... how many people actualy read those? None the less - it is the resposibility of the Captain to know the local and State rules wherever he/she boats. No different from driving a car here or abroad.
