I think the A-cat refered to is the AHPC flyer : http://www.ahpc.com.au/pdf/AHPC%20Price%20List%20A-Class.pdf

However, I don't think this boat is produced anymore. Boyer quit and AHPC is said to act as a dealor network for The Tool A-cat by Wayne Mercer, these are not produced by AHPC themselfs. Geltek does the successor, the flyer 2 and I haven't heard anything about somebody else producing this AHPC Flyer. In my book this design is discontinued and the price quote is of april 2005 which is two years old. Didn't carbon prices rise significantly since then ?
