How Often Should You Clean The Hull of Your Boat?

To optimize boat performance, hull cleaning is desirable as soon as fouling accrues. This normally happens every 4-12 weeks. There are a few factors that will have an impact on cleaning frequency, such as geographical location, water temperature and salinity but also usage patterns.

Boats that are seldom in use and mostly sit in the dock will accrue more fouling than a boat that is in frequent use. On the other hand, higher speed will slightly help reduce the growth of fouling on the hull.

These are the main factors that affect fouling:

  • Geographical location
  • Regional variations
  • Water temperature
  • Water salinity
  • Frequency and duration of boat usage
  • Boat speed

Therefore, to achieve best results, regular cleaning is recommended. This will prevent marine fouling building up.
