Headway speed is simply being able to make forward progress without going backwards (sometimes in a wicked current, you might be exceeding 6 but you need to do what it takes to keep moving ahead) no such currents exist on Winni save for the spring current toward Paugus. Simple, really. |

NO Wake/Headway is 6 MPH regardless of how much wake your boat puts out at that speed. The law is written as such that you can EXCEED 6MPH if conditions warrant it.

A 6 MPH wake is not going to affect anyone's day. I don't think a large cruiser at 6 MPH could cause any real issues, could it?

My boat at idle goes faster than most others, therefore I have to go to neutral.
Then I don't have headway and am constantly going in and out of gear in these conditions when there is a lot of traffic. Not good. --------------------------------------------- I am a retired workaholic and continuing aquaholic |

To some shore front owners it's like a tsunami that caused a seismic like wave.

![]() "Education" tells us that plowing produces more wake—which can also be attributed to "trim"—an equivalent affront to shorelines. Even a quarter-mile away, his wake came crashing down on our shoreline. "Surf's Up!" ![]() It's a good thing we're not at Spring's highest water level, or more silt would be severely eroded from shore—all the way to Meredith! .

![]() Indeed, in the photo below, the wake that struck the shore appears innocuous. Note the cruiser's wake coursing across the center of the photograph, as indicated by the two x's. Although a small wake, it is cresting between the x's—never a good sign. ![]() 2) The lake is approaching year-end's lowest level. Had this cruiser's "modest" wake struck at "full-pond", more soil (and Phosphorus) would have been released, more trees (and boulders) would fall into the lake, and more survey markers would be found in the lake. ![]() |

This was a 40 foot plus behemoth and he was plowing along making a huge wake. That idiot sailed right into the mass of sailboats without slowing and actually caused one to nearly capsize by cutting so close to it (less than 20 ft). We couldn’t believe our eyes. If I was to guess his speed I’ll bet it was under 10 mph. So yes, a wake can cause havoc at slower speeds. He may not have been going 6 but he may as well have been going 20. We were hoping the watch boat got his name or numbers. |

I do not believe you have faintest idea what you are talking about. I was over a hundred yards away from 30+ ft cruiser today, probably doing about 6, and it threw enough wake I had to scramble to turn my boat into it so I didnt get rocked from gunwale to gunwale.

When boat operate at 2/3 of hull speed or less, they make practically no wake at all. 40 foot boats would typically have a 35 to 38 foot LWL, thus their hull speed will be around 8 knots (9.3 MPH). At 6 MPH, they are clearly running at less than 2/3 of hull speed (6.2 MPH) and not making more than a minor ripple. The hull speed of a 10 foot PWC (assuming 9 feet LWL) is 4.6 MPH. At 6 MPH they are plowing like crazy and throwing a good size wake, pretty much like the photo in the first post on this thread... Here's a really neat white paper on wakes, if you like physics: https://dpipwe.tas.gov.au/Documents/...ake-151014.pdf |

What low speed does a, say, 35 ft cruiser need to go to throw a wake that breaks on itself 100 yards away?

Kawishiwi...
Its the weight/mass of the object that causes the wave energy.... a 35' cruiser could weigh up to 20,000lbs... My guess is you crossed paths with a 20,000lb underpowered brick... Woodsy

My 37' Egg Harbor weighed 40,000 lbs. It did not throw a big wake on plane, then one can always utilize the trim tabs to raise or lower the bow.

Try it out in your boat. Just plug the water line length into my original equation: (HS = 1.34 x √LWL) Then take the result and multiply it by .77 to get two thirds hull speed in MPH. If you have GPS, see how your wake looks at that speed, under that speed and above that speed. The magic speed for my boat is 4.88 MPH, when I'm really trying not to make a wake, I keep it below 5 MPH and have never heard a word from anyone about my wake. When I'm in a silly-big NWZ, (like Meredith, or the one on the Potomac River by Alexandria), I run at 6ish MPH until I'm 150 feet from docks. |

All this no wake complaining is quite entertaining. You should have spent the weekend sitting at my place. Huge, breaking waves slamming into the shoreline all weekend long, caused by all kinds of vessels, going all different speeds. I knew it going in when I bought the place, but the waves keep getting bigger and bigger. If a child or pet is in the water when some of these waves come ashore, there would be potential for serious injury.
So for you poor people that live in no-wake zones that are complaining about small ripples and white froth coming from boats, come on over and see how green the grass is on the other side of the fence! And for those who don't think these boat waves cause substantial shoreline erosion, please feel free to PM me and I will extend a personal invitation for you to come see for yourself (and I will supply the beer!). |

Thanks for taking the time to post the videos! I see no issues with your 6MPH wake.... kind of amazing how big it gets at 10MPH. Woodsy

The cruiser that threw a big wake at me Sunday was far enough away that I didnt really consider what it could throw. The only reason I was able to adjust was that the wake started breaking 80 ft away from me so that I heard it coming.

This thread is giving me a popsicle headache!!! When it comes time for me to enter a no wake zone, I utilize the "kiss" method. Since I don't have a gps on board, and my speedometer doesn't move till you are doing about 10 or 15, I have figured out EXACTLY what rpm's my boat makes NO wake at, (1200) and that's where I put it every time. 1200 rpm's - no wake, no looking back, no white, no foam, no yelling, no problem, and I have NO idea how fast I'm going. Doesn't matter... Keep it simple, stupid. Amazing how "things" get so complicated...

I saw them before they were deleted. That hull speed equation is only for mono-hull boats, multi-hull boats like yours are not the same because of the way the bow waves interact between the hulls. My 25 foot mono-hull makes a huge wake at 10 MPH. You can see it in the link below, taken on the Champlain Canal, where the speed limit is 10 ans there's no safe passage law. Bear in mind too, that the close confines and shallow water also increase the wake intensity.

At this speed the boat wanders left and right as there are no chines. When passing through the channel a decade ago, an LEO pulled me over for 3 things: Shifting in and out (because the traffic is slower than idle speed), wandering left and right, and a wake he feels was too high! After a safety, registration and sobriety check, he let me off with a warning and a note to my boat mechanic to fix the boat! WTH!

Seems like we have this exact same discussion every couple of years with the threads having all the same arguments. I'm not linking to the old thread because i don't want to revive them, but clearly there is confusion so the law must be "confusing" and needs to be re-written. Of course, there will always be those that are ignorant of the law no matter how clear it could be written. So, there will be waves, there will be idiots, and hopefully we can just relax and have another beer and enjoy the show.

To me it always comes down to common sense and respect for the shore line and other people's property. I do not think the law is confusing at all many looks for ways around the law, but for what... to go 8 mph instead of 6. Your not getting where you need to go that much faster. Relax and enjoy your on the lake

Very often on the ICW in Florida we meet up with 80' to 100" boats traveling at 10 to 20 mph. Some of them throw up wakes over 4' that can really cause problems if you don't handle them right. I have seen times in a narrow channel that I've actually done a 180 and fled to avoid a huge wake.
I cross them at a 45 degree angle....if you drive straight into them you're likely to bury your bow in the trough. Wasn't much of a problem on our lakes until the wakeboard boats showed up. Some of them produce the kind of wakes that BearIslander was talking about. Actually can be dangerous. I have nothing against them, just saying that everyone is responsible for their wake and operators should be considerate. |

I. "Boat" means every description of watercraft other than seaplanes, capable of being used or used as a means of transportation on the water and which is primarily used for noncommercial purposes, or leased, rented, loaned or chartered to another for such use. VI. "Headway speed" means 6 miles per hour or the slowest speed that a boat can be operated and maintain steerage way. VIII. "No wake area" means an area where a boat is to be operated only at headway speed. Headway speed is defined as 6MPH... so you can legally go up to 6MPH in a NWZ. The clause "or the slowest speed that a boat can be operated and maintain steerage way." is there for when the conditions are such that you have to EXCEED 6MPH... due to current, tide, etc... This is not Rocket Science! Woodsy

It is true that the statutes regarding Headway speed vs No wake appears to be one and the same. 6 mph or a speed to maintain steerage. Yet some LEOs interpret a different way. The size of the wake!
If you have a judge that goes by the law and one get cited for creating a wake then the judge will throw out the conviction if the person is traveling 6 mph. If the person claims he must travel over 6 mph to maintain steerage, this is where the judge have to make a decision. All boats have different speed to maintain steerage and outside influence such as current, wind etc. must also come into consideration. So do your homework. Unfortunately the local courts almost always side with marine patrol, so it's a no win situation unless you can justify and prove your speed! In my travels to other states, the signage makes sense. Headway speed signs in channels and passages. No wake signs in designated areas where there should be no wake. In NH there is now such thing as a 'Headway speed' area. In passages or channels it's no wake. Tough to pick your battles and to educate the public in NH.

Wow... So much wrong information...
The law defining Headway speed is absolute... you are allowed up to 6 MPH before you need to perhaps explain yourself to the MP. When the law was written, the NH legislature, knew that different boats need different speeds to maintain steerage, and that conditions such as current & wind can vary those numbers substantially. The law was written (just like the nighttime speed limit) such that the overwhelming majority of boats do not need to exceed 6MPH in normal conditions to maintain steerage, however, unlike the speed limit, there is a provision in the law that allows you to EXCEED the 6mph should the conditions warrant it. A boat ALWAYS makes a wake as it moves thru and displaces the water (its a simple energy transfer) that's just physics. So while at 6MPH while you might actually make a visible wake, there is very little wave energy in that wake so no damage is done. I have no problem at all going thru a NWZ at 5.5MPH on my GPS...

"VIII. "No wake area" means an area where a boat is to be operated only at headway speed. "
__________________ And headway speed means 6MPH or the slowest speed that a boat can be operated and maintain steerage way. So what is hard to understand about that? 6 MPH or the slowest speed does not mean JUST 6MPH. All I can say Woodsy is you do just what you want to do. But you deserve to be caught. As Real Big Guy said per Marine Patrol: Turn around and look and see if you are making a wake. I would like to educate not start an argument. But some people are so sure of themselves--- it just isn't worth it. And I do wonder if the new breed of MP is as knowledgeable as they used to be. So maybe you will get away with doing what you want. |
