My sailboat was designed in 1966 by John H. Illingworth, a very famous english architect and racer. It's named "the father of modern sailboat". Illingworth designed for Alpa company both the A9 (9 metre) the A11 (11 metres) and A8. The A11 is based upon the famous Maica, wich in the '60 won several regattas in Englend and France (in France there's a class website www.maica.fr
with beaufiful photo.
The sailboat is one of the first attempt to build in fibreglass, so very heavy, with a long keel and an attached rudder. The alpa A9 lines resembles in small, the Gipsy Moth one, as they came from the same pencil.
I own one since 15 years, have made several cruise in the Med (I use to live in Rome) and, apart from the doghouse, I like it very much.
Like all Illingworth sailboat, it's really a joy to sail.
Regarding the propeller, it's just te old way...forget the reverse...
Grazie mille (thank you a lot!).
