    The material is fairly benign and modern landfill is sealed all round to prevent leaching, hence crushing GRP hulls and burying in landfill appears to be a reasonable disposal method. I think the problem with recycling is that the volumes are not that high, for example in the marinas that I have recently visited, there would be no more that 20 boats in total that appear to be abandoned. Perhaps it's not really a problem and current methods of disposal are suitable.

    You need to think in geological time not human time. Ben Nevis was once the height of Everest and is now only about 1,400 meters above mean sea level.

    That's degraded well, then!

    I see Mr Tydeyman has had lots of airtime, extolling how Fairline were made 50 yrs ago . He does have considerable expertise in yacht design & construction, but not very good at management of yacht construction

    And what has happened to all that material. It must be polluting the oceans something awful.

    And here's a thought.. shouldn't we do something about Etna? It is belching tons of pollutants every day.. We need to fit a flue scrubber to the summit to prevent noxious gases being allowed into the environment.

    Ok, so here's a question..
    When rock is eroded down to fine dust and it ends up in the ocean via rivers or the wind, how its it different to glass and (inert) polyester that is equally finely ground down to micro particles?

    And how wold making artificial reefs out of degrading GRP boats compare to the millions of tones of various "filler" powders that are used in "essential" products like makeup?
