Sorry Rod, on this occasion the BA are not entirely to blame, IMHO. It is more the responsibility of these pr**s at the BSS office in Watford, who are more used to dealing with those overblown sewer pipes floating in ditches elsewhere in the country, which are otherwise known as 'Narrow Boats'.
Flaming heck, they don't even seem to understand the difference in flash points and flammability between petrol and diesel.
Why on earth do we have to change perfectly serviceable fuel hoses for example, simply because they don't hav a purely arbitrary marking on them? If it's good enough for Volvo Penta, it's good enough for me! The MOT test does not prescribe such stupidity, and I would argue that this particular requirement (the MOT) has much more impact on transport safety than the BSS (across the WHOLE Inland Waterways network) ever has or will have!
For the vast majority it's jobs for the boys once again. Most boating accidents targeted by this scheme are caused by stupidity, and not test devised by man can avoid this, unfortunately.
P.S. Glad to be able to resume our 'normal' service.
