INTRODUCTION

• When you neglect to perform hull cleaning, the
  boat is said to slow down and doing maneuver will
  also become a hard thing.
• Fouling will be developed over time and this
  eventually increases the friction in the boat.
• This can be held as the reason for slowing down
  of the boat.

PROCESS IN HULL CLEANING

• The removal of fouling is the main activity here
  and this is done with the help of a brush, soft
  sponge, scraper and more.
• The divers focus to clean every part of the boat
  including all the fittings.
• In addition to, the running gear will also be
  checked and when cleaning is necessary for the
  running gear that will also be performed.

5
DIFFICULTIES INVOLVED

• Generally, the hull will be brushed to remove the
  particles. There wont be any grip for the divers
  to do this work.
• The tides will prevent you from being stable in a
  position which is comfortable for you during
  working.
• The place will be dark and you will not be
  visually strong to do the cleaning. When going
  deeper and deeper in water, it would be hard for
  you to see anything.

ADVANTAGES OF HULL CLEANING

• The hull cleaning is essential for the effective
  running of the boat.
• The performance of the boat will be increased and
  improved.
• When done in a proper manner, the fuel
  consumption of the vessel will also be reduced.

7
CONCLUSION

• Leaving all the other things, hull cleaning can
  be considered as the important task in underwater
  maintenance.
• To perform hull cleaning, in the beginning, the
  ships would be brought to the dry dock.
• Later to make the process easier the divers are
  trained to perform the process.
