<font color=blue>Any regular carpet shop will supply and fit Nick and it saves tramping all the crap into the main cabin. Remember to take it up regularly and let it dry out as it can cause bubbling (Osmosis?) on the fibreglass if left permenantly wet.
I got a very nice piece of end of roll waterproof kitchen carpet from a local carpet shop for £25 and fitted it myself. Save the rest of the money for the 'D' word !
