    a mere flower water sprayer used for wetting a ship's sides?

    Hello everybody!

    I am sorry to be asking such a childish question but I would like to make sure that I get the meaning right.

    AHR measurements – when and how?
    o All surfaces can be measured provided they are hard enough (silicone coatings on the next day)
    o Remember to calibrate the unit first!
    o When the sensor unit is rolled over a silicone coating the stylus can due to high friction bounce rather than smoothly follow the surface features. Wet the surface prior to measuring
    o By standard flower water sprayer on Vertical Sides
    o By wet cloth on Flat Bottom
    o Do not roll the measuring unit too fast
    o Guidelines for use are on the Marine Technical Portal

    AHR stands for Average Hull Roughness.

    Does the author really mean spraying water on vertical sides of a ship by means of a flower water sprayer?

    As far as I know, a flower water sprayer is used for watering flowers or plants.

    What do you think?

    Yes. The measuring unit must test an area that's small enough to be wet with such a sprayer.
    I am not a teacher.

    And there must be a standardised version of this, which I had no idea about.
