"..for the avoidance of any doubt, the broads are not legally a national park and do not come under the national park legislation, and nor will they." Parliamentary Under-Secretary of State for DEFRA (Hansard 2015)
Presuming the mechanism is a simple cable operated hand winch system it is relatively simple to convert to a powered system , if yours is one of the rarer chain systems (more commonly fitted to Brooms than Aquafibre 35’s) then it’s slightly more complicated. A good friend of mine has recently (last year) converted his Broom to powered as opposed to manual his was the chain operated type and if memory serves me correct it cost him a shade under £1500 and it was carried out by Boulters in Horning .
