CONCORD, N.H. (AP) – The House has approved a two-year trial boat speed limit on New Hampshire’s Lake Winnipesaukee.

The House voted 236-111 Wednesday on a bill that set a 45 mph daytime limit and 25 mph nighttime limit on the state’s largest lake.

Supporters argued the two-year trial would be plenty of time to test speed limits. They say speeders are spoiling the lake for other users.

Opponents argued the limits are unnecessary. As proof, they pointed to a Marine Patrol study last summer that found few boats exceeded the proposed limit. Opponents said it made no sense to pass a law in hopes a small, inconsiderate group would change its habits. They also argue the speed limits would be unenforceable since boats aren’t required to have speedometers.

The House passed a bill two years ago to impose limits on all lakes and rivers, but the Senate killed it.
