If you want to find someone local (ish) to do the repair then Jo Lines near Bristol comes highly recommended. One word of caution, I'm told AHPC use a 'special' gelcoat on the Capricorn which apparently is very difficult to match and considerably more expensive than normal - not sure if the same applies to your A. Hope that you are still enjoying it, Nacra 140 now at a new home in Rutland and it's berth taken by a Capricorn.
