Clearwater Rating Ltd

A not for profit company.

Clearwater Rating addresses a need in the leisure marine market for an objective, independent assessment of the environmental credentials of a boat or superyacht.

The Clearwater Rating system has been carefully researched to take into account environmental legislation and realistically incorporated best practice. It enables a manufacturer or owner to work though clearly defined steps that examine the impact of a leisure vessel upon air and water quality, energy consumption, noise pollution, seabed, foreshore, wildlife and global resources. One of seven ratings, from Bronze through Gold, can be earned.

Marine GRP Recycling – GRP boats disposal and recycling

We give the end-of-life GRP boats the treatment our planet and the boats themselves deserve.

The boats are not left to rot in harbours and fields, nor they are disgorged to landfills around the country.

We remove all the reusable bits, clean dangerous substances off the hulls, cut and compact the hulls to provide cleaner fuel for Waste-to-Energy plants.
