[upthesaukee]

X. (a) No person shall operate a vessel on Lake Winnipesaukee at a speed greater than is reasonable and prudent under the existing conditions and without regard for the actual and potential hazards then existing. In all cases, speed shall be controlled so that the operator will be able to avoid endangering or colliding with any person, vessel, object, or shore.
(b) Where no hazard exists that requires lower speed for compliance with subparagraph (a), the speed of any vessel in excess of the limit specified in this subparagraph shall be prima facie evidence that the speed is not reasonable or prudent and that it is unlawful:
(1) 30 miles per hour during the period from 1/2 hour after sunset to 1/2 hour before sunrise; and
(2) 45 miles per hour at any other time.
(c) The speed limitations set forth in subparagraph (b) shall not apply to vessels when operated with due regard for safety under the direction of the peace officers in the chase or apprehension of violators of the law or of persons charged with, or suspected of, any such violation, nor to fire department or fire patrol vessels, nor to private emergency vessels when traveling to emergencies. This exemption shall not, however, protect the operator of any such vessel from the consequences of a reckless disregard of the safety of others.
(d) The speed limitations set forth in subparagraph (b) shall not apply to boat racing permitted under RSA 270:27.
