Ok, so I tried to find some kind of information on the internet (and on this site using the search function), but I haven't come up with a straight answer to two questions: (1) Is an operator of a pontoon boat required to have a PFD? (2) And, can one receive a DUI while operating a pontoon boat? Couldn't find anything, so I did a little bit of research, and was wondering if I was off-base, or had possibly missed something. RCW 79A.60.040 (1) It shall be unlawful for any person to operate a vessel in a reckless manner. (2) It shall be a violation for a person to operate a vessel while under the influence of intoxicating liquor or any drug. A person is considered to be under the influence of intoxicating liquor or any drug if: (a) The person has 0.08 grams or more of alcohol per two hundred ten liters of breath, as shown by analysis of the person's breath made under RCW 46.61.506; or (b) The person has 0.08 percent or more by weight of alcohol in the person's blood, as shown by analysis of the person's blood made under RCW 46.61.506; or (c) The person is under the influence of or affected by intoxicating liquor or any drug; RCW 79A.60.160 Personal flotation devices required — Penalty. (1) No person may operate or permit the operation of a vessel on the waters of the state without a personal flotation device on board for each person on the vessel. Each personal flotation device shall be in serviceable condition, of an appropriate size, and readily accessible. Right, so I know that for a 'vessel' dui's can be issued and PFDs are needed. But, RCW 79A.60.010 Definitions. (29) "Vessel" includes every description of watercraft on the water, other than a seaplane, used or capable of being used as a means of transportation on the water. However, it does not include inner tubes, air mattresses, sailboards, and small rafts or flotation devices or toys customarily used by swimmers. My question is: Does a pontoon constitute a 'vessel'(allowing for DUI and lack of PFD penalties) or is it more akin to the exclusion for "inner tubes, air mattresses, and small rafts?" By the way, I don't plan on getting drunk in my pontoon boat with no PFD. I know some of you drink a little on the pontoon and a lot don't have PFDs, but has anyone talked to an enforcement officer?
