  3. How to use
  4. @ Attach the water guide tube to the main device. At that time, you should hang the fall prevention cord on the ring of the main unit.
    A Set the KENDRAFT on the hull near the center draf mark and descend towards the
    water surface.
    After landing, the water rises through a water tube approximately 5 meters long and
    stops at the water surface inside the pipe.
    Read the draft mark located at the center of the float on the water surface with a mirror.

    B If you attach a waterproof light to the mirror at night, you can see draft marks just as clearly as during the day.

    C It can only be used to read the draft marks at port & starboard sides in the center of the hull. The bow and stern are visually read as usual.

    For draft surveys, the center draft mark readings account for 75 % of the average draft reading. Therefore, it is more important to read the center draft marks correctly. On the other hand, the readings of the bow and stern draft marks each account for 12.5 %.
