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.

NJs law regarding PWCs and No Wake Zones.






From the office of the Attorney General

Personal watercraft operators are reminded that New Jersey personal watercraft laws have recently changed. The law now states that a person is not permitted to operate a personal watercraft above minimum headway speed within 100 feet of buoys or signs that mark the boundaries of a swimming area, the shoreline, any person in the water, or residential dwelling units.

Additionally, personal watercraft are not permitted to be operated in such a manner so as to make the vessel completely leave the water or otherwise become airborne within 100 feet of another vessel.

Preexisting laws that remain unaffected by the recent changes require that personal watercraft be operated only between sunrise and sunset and during times of good visibility. Personal watercraft are not permitted to be operated within the confines of the Point Pleasant Canal in Ocean County, or the Cape May Canal in Cape May County.

Personal watercraft operators must be at least 16 years of age, and must have a boating safety certificate in their possession.
