Lake Champlain is a big lake, with 125 miles of water that crosses state lines, borders Canada, and sees everything from kayaks and fishing boats to tall-masted sailboats and active car ferries on any given summer day. That variety is part of what makes it such a great place to boat, but it also means there’s more to know before you go than on a smaller, single-jurisdiction lake.
Lake Champlain boating regulations come from three sources (New York State, Vermont, and the U.S. Coast Guard) and they don’t always line up perfectly. Here’s a practical breakdown of what applies, and what to keep in mind to keep your day on the water safe and legal.
Boating Safety Certificates
As of January 2025, every motorboat operator in New York State is required to carry a valid boating safety certificate, regardless of age. This is the result of Brianna’s Law, named after an 11-year-old girl killed in a boating accident in 2005. The law was phased in over several years and is now fully in effect.
If you’re launching from or operating on the New York side of Lake Champlain, this boating regulation applies to you. Boating safety courses are available online and in-person through the NYS Office of Parks, Recreation and Historic Preservation. Out-of-state certificates are recognized by New York, so if you completed a safety course through another state’s program, you’re covered; just carry proof.
Vermont has its own requirement: anyone born after January 1, 1974 must complete an approved boating safety course before operating a motorboat on Vermont waters, per the Vermont Fish & Wildlife Department. That bar is lower than New York’s current standard, so if you’re certified for New York, you meet Vermont’s requirement as well.

Speed Limits & No-Wake Zones
New York and Vermont approach speed limits slightly differently, and both apply on Lake Champlain depending on which side of the lake you’re on.
New York: Per New York State boating law, speed is limited to 5 mph within 100 feet of the shoreline, any dock, pier, raft, float, or anchored boat. The general open-water speed limit is 45 mph during daylight hours, and 25 mph from sunset to sunrise. Local ordinances can extend the nearshore slow zone up to 1,500 feet from shore in certain areas, so it’s worth knowing the specific Lake Champlain boating regulations near your launch.
Vermont: Vermont’s nearshore limit is more conservative. Per the Vermont Department of Environmental Conservation, speed must remain under 5 mph within 200 feet of the shoreline, any dock, swim area, person in the water, or anchored vessel. The extra 100 feet matters, especially when you’re running parallel to a developed shoreline.
No-wake zones on Lake Champlain are marked with buoys and should be treated as hard stops, not suggestions. You’re legally responsible for any damage your wake causes to other boats, docks, and shoreline, regardless of whether a posted limit is present.
Required Safety Equipment
Whether you’re on the New York or Vermont side, U.S. Coast Guard requirements apply across the entire lake. Here’s what you’re required to have on board:
Personal Flotation Devices (PFDs)
- One Coast Guard-approved PFD for every person on board, in appropriate sizes
- Vessels 16 feet or longer must also carry at least one Type IV throwable PFD (such as a ring buoy or seat cushion) that is immediately accessible
- Anyone being towed (water skiing, tubing, wake surfing) must wear a PFD; This is required by law in both New York and Vermont
- Children 12 and under must wear a PFD at all times while on deck and underway
Fire Extinguisher
- Required on motorized boats under 26 feet; at minimum one Coast Guard-approved B-1 extinguisher
- Larger vessels require additional extinguishers; check current USCG requirements for your boat’s length and class
Visual Distress Signals
- Required on Lake Champlain. The lake qualifies as a “navigable water of the U.S.” and USCG requirements for visual distress signals (flares or electric distress lights) apply
Sound-Producing Device
- A horn or whistle capable of producing a four-second blast audible at a minimum of half a mile is required on all vessels
Navigation Lights
- Required between sunset and sunrise and in periods of reduced visibility; know your boat’s light configuration and make sure all lights are functioning before you head out after dark
Boating Under the Influence (BUI)
Both New York and Vermont treat boating under the influence the same way as driving under the influence, with the same legal blood alcohol limit of 0.08% and similar penalties including fines, license suspension, and potential criminal charges.
Vermont additionally sets a stricter limit for anyone under 21: per Vermont boating law, a BAC of 0.02% or higher is considered impairment on the water. The U.S. Coast Guard also enforces federal BUI law on Lake Champlain and has authority to board and inspect any vessel.
If you’re planning a day that includes alcohol, designate a sober operator. There’s no exception for “just crossing the lake.”
No-Discharge Zone
Lake Champlain is a designated No Discharge Zone (NDZ) under New York State law. This means that any vessel equipped with a marine toilet or sanitation system is prohibited from discharging any treated or untreated sewage into the lake. Type I and Type II marine sanitation devices that discharge overboard are not permitted.
Vessels with an onboard head must have a Type III marine sanitation device (a holding tank) installed, and that holding tank must be emptied at a certified pumpout facility on shore. Operating the overboard discharge valve while on the lake is a violation even if the system is certified to treat waste.
Pumpout facilities are available at several marinas around the lake. Plan accordingly before you leave the dock.
Aquatic Invasive Species: Clean, Drain, Dry
Lake Champlain already has established populations of zebra mussels, spiny waterflea, Eurasian watermilfoil, and other invasive species. The stakes for preventing their spread to other water bodies are high. Both New York DEC and the Vermont Fish & Wildlife Department require that you clean, drain, and dry your boat and trailer before launching and after leaving the water.
In practice, this means:
- Clean: remove all visible plant material, mud, and animals from the hull, trailer, motor, and any gear that touched the water
- Drain: empty all water from the bilge, live wells, bait buckets, and any compartment that holds water, away from the lake
- Dry: allow your boat, trailer, and equipment to dry completely before using it on another water body. Five days of sun exposure is recommended if hot-water rinsing isn’t available
Several launch sites on Lake Champlain have boat washing stations available. Use them. Violations can result in fines under both state laws.
Towing Rules (Water Skiing, Tubing, Wake Surfing)
When towing anyone behind your boat on Lake Champlain, New York and Vermont law both require that you have an observer on board in addition to the operator, someone whose sole job is to watch the person being towed. One person cannot legally drive and observe simultaneously.
Additional towing rules to know:
- The person being towed must wear a PFD (Type I, II, or III, not a Type IV throwable)
- Towing activities must maintain at least 200 feet from shorelines, docks, swim platforms, and anchored vessels unless departing from or returning to a launching or docking area
- No towing from sunset to sunrise
Navigating Around the Car Ferries
Lake Champlain has three active car ferry crossings that operate between New York and Vermont throughout the boating season:
- Fort Ticonderoga Ferry between Ticonderoga, NY and Shoreham, VT
- Essex-Charlotte Ferry between Essex, NY and Charlotte, VT
- Cumberland Head Ferry between Plattsburgh, NY and Grand Isle, VT
These ferries are large, operate on a fixed schedule, and have very limited ability to maneuver or stop quickly. Under U.S. Coast Guard rules, vessels with restricted maneuverability have right-of-way. Give the ferries a wide, early berth; crossing ahead of them is not a race worth entering. If you’re uncertain whether a ferry is moving, assume it is.
VHF Radio & Emergency Contact
On a lake the size of Champlain, a VHF marine radio is strongly recommended, especially if you’re venturing into the main lake or planning a longer cruise. Monitor Channel 16 whenever underway; it’s the international distress and hailing frequency and is monitored by the U.S. Coast Guard.
Emergency contacts on Lake Champlain:
- U.S. Coast Guard Sector Northern New England: VHF Channel 16 or call 1-800-424-8802
- New York State Police Marine Unit: 518-897-2000 (Troop B, covering Lake Champlain)
- Vermont State Police Marine Division: 802-244-8775
