New Hampshire Boating Restrictions: A Guide for Lakes Region & White Mountain Homeowners
Essential information for boaters and waterfront property buyers in NH.
1. The NH "150-Foot Rule" (Safe Passage & Headway Speed)
New Hampshire law (RSA 270-D:2) requires a mandatory 150-foot safety buffer. You must maintain headway speed—defined as 6 mph or the slowest speed necessary to maintain steerage—whenever you are within 150 feet of:
- Shorelines and private docks
- Other vessels or swimmers
- Rafts and mooring fields
- Permitted swimming areas
Expert Tip: This rule ensures the tranquility of "quiet coves," which are highly sought after in the NH waterfront real estate market.
2. Speed Limits on Major New Hampshire Lakes
While many smaller ponds have a default 10 mph limit, our larger lakes have specific statutory speed limits to ensure safety during peak summer months.
| Lake Name | Daytime Speed Limit | Nighttime Speed Limit |
|---|---|---|
| Lake Winnipesaukee | 45 MPH | 30 MPH |
| Squam Lake | 40 MPH | 20 MPH |
| Lake Sunapee | 45 MPH | 25 MPH |
| Newfound Lake | No state limit (open water) | 20 MPH (recommended) |
*Nighttime is defined as 30 minutes after sunset until 30 minutes before sunrise.
3. Jet Ski and "Skicraft" Restrictions
In NH, a "Skicraft" is a motorized vessel less than 13 feet long, capable of exceeding 20 mph. These have specific restrictions:
- The 75-Acre Rule: Skicraft are prohibited on public water bodies smaller than 75 acres.
- Total Bans: Skicraft are strictly prohibited on Squam Lake and Little Squam to protect wildlife and the environment.
- Winnipesaukee Restrictions: While allowed in "The Broads," they are restricted in certain coves and areas like Crescent Lake (Wolfeboro).
Frequently Asked Questions (FAQ)

Many smaller lakes in the Southern White Mountains have HP limits (e.g., "10 HP Max") or are restricted to electric motors only to prevent erosion and noise.
