No wake zones

Because of the myriad of boat hull designs, there is no way to define what is acceptable wake height, and what is not. Every hull is different and creates a different wake and that wake all varies with the forward speed of the boat.

The important clause here is "maintain steerage". Maintaining proper control of your boat is paramount and trumps ALL! Currents, boat traffic, wind & weather can all affect at what speed steerage can be maintained. For example, in the spring the Weirs Channel usually has a 5 MPH current... to overcome that current you have to go a minimum of 7-11 MPH... guess what your boat is making a pretty good wake!

The 6 MPH speed is essentially the standard acceptable speed that is universally recognized as the maximum speed necessary to maintain steerage for 98% of the recreational boats. Why 6 MPH and not 5 MPH? No idea!

A couple of points that I would disagree with:

The movement of water across your hull is what leaves a wake, not necessarily your boat speed. For example: If you maintain a constant stationary position against the current in the Weirs Channel in the spring your boat will be leaving a wake, though not moving at all.

To travel against the current in the Weirs Channel (or anywhere with a strong current) the same 5 to 7 mile per hour speed is all that is needed. Don't confuse the speed of the water across your hull with your actual speed over the stationary land. Your boat speedometer (if not GPS) will indicate a higher speed than you are actually going because it will read off the pressure sensor and will not correct for water flow.

Many people are use to one "No Wake" speed RPM setting and fail to account for the movement of water underneath them and adjust accordingly. Quite often that is the reason that the Weirs Channel backs up so much. It would be nice if people looked behind them to see if their slow speed is causing a backup or handling problem for the boats following them. Not all boats react the same way at slow speeds.
