Clearwater Rating

Our recently launched Clearwater™ Rating assessment scheme, provides an independent and unbiased evaluation of a vessel’s environmental performance. Clearwater™ takes a different and more representative view of environmental performance to other rating schemes, focusing on how well the boat is designed to prevent pollutants from entering the air and water in which it operates, and not just on the manufacture of the vessel or it’s recyclability.

As the majority of boat materials & manufacturing processes still have some way to go before they can be truly classed as ‘environmentally friendly’, we believe it is important to focus on how boat owners can identify those boats in the market place that have been designed to reduce the impact on the environment where they sail.

Clearwater Rating results chart -2 starsThe Clearwater assessment begins with the builder or owner downloading a free “calculator” and ticking the boxes that reflect the features of their boat.  The calculator indicates the eventual Clearwater Rating that may be expected, as shown in the result table to the left. If the builder wishes to progress to certification, HPiVS sends an expert, audited assessor to undertake a full evaluation of the vessel’s design & systems, after which the a rating is awarded between one and three stars, with three being the highest and best rating. Once a certificate is issued, the boat and its documentation may carry the appropriate Clearwater Rating logo.

Assessment criteria includes:

  • Bilge water cleanliness
  • Fuel system integrity
  • Lubricating/Hydraulic oil handling
  • Marine spill kit
  • Anti-fouling
  • Black water handling
  • Grey water handling
  • Garbage facilities
  • Anchoring systems
  • Use of alternative energy or fuel
  • Greenhouse gasses in component parts
  • Exhaust emissions
  • Noise emissions
  • Energy Efficiency Design Index
  • Environmental procedures and processes, and how they are documented
As the rating focuses on a vessels’ outputs and emissions, it would not therefore be possible for a vessel powered primarily by fossil fuels, for example, to achieve a 3* rating. The scheme is designed to recognise those boat owners who have put measures in place to ensure they minimise their impact on the waters and environments in which they sail. The first recipient of a three-star Clearwater Rating was Hydrogenesis, the first hydrogen-fuel cell powered boat in UK.

This new approach with Clearwater™ allows our customers to show an advanced commitment to corporate social responsibility and sustainability that goes beyond the requirement of legislation, setting benchmarks to raise the environmental standards of operations. The rating is non-compulsory, setting those vessels with a certified Clearwater Rating apart as an example of industry best practice.
