I don't do recounts every month so it seems that my estimate of 150 Spitfires isn't too far of the mark. As a result I don't feel that I'm knocking the Spitfire design.

The claim of 250 boats was actually given to me in, I think, late 2005.

Going on your data I guess I was right not to believe that claim.

Just under 200 is what I would consider believable. From what I know from other builders, modest designs from small builders typically sell on average around 25 boats a year if they are succesful. That is what the individual F16 builders are doing as well. I think VWM is now at 45 boats since their launch in januari 2005, this is on average 18 boats a year and that does includes the year of the lauch were it is very hard to sell more then a handful of boats. AHPC sold on average 20 Taipan 4.9's ever since the year after the first year when the boat was launched.


For the Spitfires this rule of thumb would come out at :

march 2001 till september 2007 = 6 and half years a 25 boats a year = 163 boats.

March 2001 boat 011 to september 2007 boat 191 => 180 boats in 6 and halve years = 30 boats a year on average.

Seems both these principles are in agreement with eachother.
