Evaluation of noise and gas emission of engines

* NOTE: Legislative Degree 11th january 2016, n.5, defines “Recreational units “ as “boats”, “vessels” and “jet ski”


    •    Boat: a recreational unit with hull length larger than 10 meters and lower than 24, indepently from the driving force.
    •    Vessel: a recreational unit with hull length between 2,5 and 10 meters, indepently from the driving force and excluding jet skis
    •    Jet ski: a recreational unit with hull length lower than 4 meters, that use sas driving force a water pump and intended to be activated by oneor more person seasted, standing or on kneees instead of inside of it.
2013/53UE Directive includes in the term “recreational unit”  “boats” and “jet ski”, also partially completed, so defined:
1) «recreational unit», a recreational boat or a jet ski;
2) «recreational boat», any recreational unit, excluding jet skis, intended to sport and leisure activities with hull length between 2,5 and 24 meters, indepently from the driving force;
3) «jet ski», a recreational unit intended to sport and leisure activities with hull length lower than 4 meters that use as driving forcea water pump and intended to be activated by one or more person seated, standing or on knees instead of inside of it;


Legislative degree 11th  January  2016, n. 5, defines a different classification, that  recognize in Italian system the 2013/53 directive :


    1.    a) recreational unit: any product intended to sport or leisure activities, classified as recreational boat or recreational vessel or jet ski
    2.    b) recreational boat: a recreational unit with length larger than 10 meters and until 24 meters indepently from driving force;
    3.    c) recreational vessel: a recreational unit with hull length between 2 meters and 50 centrimetes and 10 meters, indepently from driving force and excluding jet skis;
    4.    d) jet ski: a recreational unit with hull length lower than 4 meters, that makes use of a water pump as main propulsion source, and intended to be activated by one or more person seated, standing or on knees instead of inside of it;
With the new 2013/53 directive all marine engines (inboard, stern drive and outboard) have to report the CE branding that attests the compliance of the “product” to the relevant requirements of the Directive itself. They have to be “certified”, for gas and/or noise emission, by the following table: EVALUATION OF NOISE AND GAS EMISSION OF ENGINES
