“Slow -No Wake…” What does that mean?

SNWSignTo make our “slow no wake” zones more enforceable, we are interested in getting your thoughts on writing a definition of “slow-no wake” in law.  This is NOT open for formal testimony , we’re simply interested in your ideas.  Please comment in the field below! 

The current draft definition is:

250-010-0010 Definitions

(8)”Slow–No Wake” means operating a boat at the slowest speed necessary to maintain steerage and that reduces or eliminates waves that appear as white water behind the boat.

The definition would then be applied to the existing basic rule 250-010-0025, and in all the local and special area rules in Division 20 that use the term slow-no wake.

250-010-0025 Basic Rule for “Slow-No Wake”

(1) No person shall operate a boat on the waters of this state in excess of a “Slow-No Wake”, maximum 5 MPH speed within 200 feet of a boat launch ramp, marina with a capacity for six or more moored vessels, floating home/boathouse moorage with six or more contiguous structures, and locations where persons are working at water level on floats, logs or waterway construction.

(2) Section (1) of this rule does not apply to commercial vessels or vessels engaged in navigation on rivers where a speed in excess of 5 MPH is needed to ensure safe passage.

OUR QUESTION FOR YOU:

Would you like to keep the reference to Wake“maximum 5 mph” within the basic rule, or would you be in favor of eliminating the reference to 5 mph?  An argument for keeping the “maximum 5 mph” is that it gives boaters a point of reference; an argument for eliminating the 5 mph reference is that it implies to some boaters that they can go 5 mph even if that speed causes their boat to plow and create a large wake. If the 5 mph reference was eliminated the basic rule might look like this:

250-010-0025 Basic Rule for “Slow-No Wake”

(1) No person shall operate a boat on the waters of this state in excess of a “Slow-No Wake” speed within 200 feet of a boat launch ramp, marina with a capacity for six or more moored vessels, floating home/boathouse moorage with six or more contiguous structures, and locations where persons are working at water level on floats, logs or waterway construction.

(2) Section (1) of this rule does not apply to commercial vessels or vessels engaged in navigation on rivers where a speed in excess of “slow-no wake” is needed to ensure safe passage.

  1. No wake speed to me is minimum speed to maintain steerage way. I have seen minimum speeds defined as speeds between 4 and 8 mph or knots. I know that a knot is a bit faster than a mph, but many recreational boats use speed meters calibrated in mph vs knots. The problem I see is the definition of what wake looks like and it must be defined. I think it is just assumed everyone knows what a no wake behind a boat looks like. I bet that’s not true. Some vessel shapes do not leave white water behind them but generate good sized pressure waves off either or both the bow and stern which result in decent sized wake waves at the beach or dock.

    • Thanks for your comment, Ron. The Board approved a new definition in 2015 of slow-no wake that is very close to your assessment: “Operating a boat at the slowest speed necessary to maintain steerage and that reduces or eliminates waves that appear as white water behind the boat.”

  2. Please do not remove the 5MPH language from the current slow no wake law. 5MPH is objective and can be measured, without this the law becomes completely subjective leaving it to marine officers to make the call on what is or is not a violation. Boat operators need a clear understanding of what is legal and expected while under way. Anything that moves threw water makes a “wake” the wording should be 5 MPH minimal wake.

    It appears this is be done to appease the non-motorized boaters operating in the Holgate channel. There are several large non-motorized boats (Dragon boats) that continually exceed the 5MPH limit in this area, they feel that because they are humane powered and not licensed they are exempt from the law. I believe that ALL watercraft need to limit their speed and follow the law.
    There is no benefit to boaters to have the 5MPH removed. it will only lead to confusion over what is expected from a boat operator .

  3. For the responsible boater, it doesn’t make a difference whether it says “Slow-No Wake” or “maximum 5 mph” both will cause the boater to go idling speed. I treat them the same.

    For the irresponsible boater, I think it also doesn’t matter — they’re still going to ignore them and go faster than they’re supposed to go.

    Has anyone done a study comparing how boaters behave with each type of sign, whether one really causes one group to go slower than the other? When I first heard of the issue, I thought people were over-thinking it since I treat them as though they’re synonymous. I’d really be surprised if it really makes a difference.

  4. I do not support keeping the reference to 5 MPH in the rule. It allows for confusion in a couple of different ways. Many boaters have GPS, and speed over ground is increasingly the only speed information available. So when operating in a current a boater may see a speed of 4 MPH, but may be going upstream against a 2 MPH current, and have a 6 MPH speed through the water. A boater using GPS SOG may not realize the violation. Similarly, a boater traveling down bound with a 2 MPH current and 5 MPH speed through the water show 7 MPH over the ground. I have no idea how sophisticated law enforcement radar is, but I can envision some difficulty in getting true speed readings.

    The draft does not define “white water behind the boat”. Some boats that I frequently operate leave a “white” wave even at low speeds. The “white” dissipates at some distance from the transom. This happens even when the height of the wave is quite small. If we truly expect “no wake”, then most boats will not be able to make headway in waters with any significant current. North Portland Harbor, for instance. It may be more reasonable to establish a maximum wave height rather than try to define the wake by the color of the water.

    Jean Quinsey, Vice-Chair
    Oregon State Marine Board
    PO Box 14145
    435 Commercial St NE #400
    Salem 97309-5065

    Chair Tonnensen and Vic-Chair Quinsey,

    I am submitting this letter as formal testimony on behalf of the Urban Greenspaces Institute regarding the Marine Board’s proposal to more clearly define “slow no wake.” Our presumption is the Marine Board would like to, and should, close a huge loophole in the “slow-no wake” zone rules which allows boats operating at less than 5 mph referenced in the current rule to still generate huge wakes with boats operating with Wave Enhancement Devices.

    We have observed, time and again, such boats operating in the Holgate Channel and Ross Island Lagoon “slow-no wake” zone and agree there is a need to address this issue, both for boater safety and environmental concerns.

    Our position is that BOTH the 5 mph limit AND “no wake” objectives are important to retain in the rule. We would prefer to see both retained in a new rule. The 5 mph speed limit is as much as safety issue as the “no wake” provision. Each has its importance with regard to boater and water user safety, whether the user is in a motorized craft, paddle boat, paddle board, or swimming. Similarly, even a boat traveling well below 5 mph has the capacity of producing dangerous wakes that pose a danger to other river users and to the environment, owing to erosion of banks in sensitive areas such as the Ross Island lagoon and Holgate Channel.

    Therefore, we strongly support the Marine Board’s effort to make “slow-no wake” zones more enforceable and support the draft definition of “slow-no wake” which reads:
    “250-010-0010 Definitions
    (8)”Slow–No Wake” means operating a boat at the slowest speed necessary to maintain steerage and that reduces or eliminates waves that appear as white water behind the boat.”

    However, as noted above, we continue to feel strongly that a 5 mph maximum speed is necessary for public safety and protection of the environment. We are pleased that the Marine Board recognizes the importance of enforcement of the “slow-no wake” zone and the need to clarify the definition accordingly. Please ensure BOTH wakes from craft operating at less than 5 mph through use of WED’s and safe speeds (5 mph) are contained in any new “slow-no wake” rules.

    Respectfully,
