Why there are no wake zones

In fluid dynamics, a wake is the region of disturbed flow (usually turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body. In incompressible fluids (liquids) such as water, a bow wake is created when a watercraft moves through the medium; as the medium cannot be compressed, it must be displaced instead, resulting in a wave. As with all wave forms, it spreads outward from the source until its energy is overcome or lost, usually by friction or dispersion.

btw. Click on the pictures to read the boat reg. #s, need a better view. email me at bigcreekwatch@gmail.com and I will be happy to furnish you with closeups.



Underlining and bold by me. Please notice the phrase “until its energy is overcome or lost” IN the case of a boat moving close to shore or between two close shores the wake’s eneregy is dispersed or spent on the shore line as it washes away mud and soil. This mud, soil and vegetation, now displaced by the wake sinks to the bottom where it builds up and reduces the depth of the waterway.

§ 13:82-1.7 Speed

(a) No person shall operate a vessel in a manner where the speed and/or wake of the vessel may
cause danger or injury to life or limb or damage to property.

(b) All vessels shall reduce speed to slow speed/no wake when passing:
1. Any marina, pier, dock, wharf or abutment at a distance of 200 feet or less, except on Lake
Hopatcong, in accordance with N.J.A.C. 13:82-3.11;

2. Work barges, platforms or floats while actually engaged in work related activity;
3. Through bridge openings of 400 feet or less;

4. Through lagoons, canals and confined areas of less than 200 feet in width;

5. Vessels not under command;

6. Emergency vessels displaying sequential flashing or rotating blue lights; or

7. Vessels engaged in activities recognized by the Coast Guard displaying rotating or sequential flashing red and yellow lights.

(c) "Slow speed/No wake" as used in this section means the speed at which a vessel moves through the water and is able to maintain minimum headway in relation to the vessel or structure being passed and producing the minimum wake possible.

(d) State Police, on the recommendation of the Commission or on its own initiative, may designate a specific area not included in (b)1 through 6 above as a temporary slow speed/no wake area based on congestion, visibility, safety, or other good cause. All vessels moving through these areas shall reduce their speed to slow speed/no wake within a 200-foot radius of the sign or buoy, in addition to any restriction under (b) above.

(e) No person shall place, anchor, or construct any buoy that states or implies that an area is a "Slow Speed/No Wake" area except as provided in (a) through (d) above. The State Police may remove or have removed any such unauthorized buoy.
