I'm sorry to inform you that we have only one 1 picture of an I-17 and only 2 of A-cats (of which one is Dave Carlson foiling catnip = banned by A-cat rules these days).
I can't quite remember why we have so little pics of these makes (Notch, notch, wink, wink)
Wouter,
Do you think that the "F16 HP" background on the link you provided has anything to do with it? Your link contains this quote "This page shows all the pictures of acceptable quality that were taken by Kirt Simmons of the Formula 16 HP group at the Spring Fever 2002 regatta." It is not surprising to me that there would be few pictures of the I-17R or A-Class boats! Kurt was taking pictures to promote the Formula 16 HP group!
I had forgotten that Jerry and Hilary Kailin had taken their T4.9 to Spring Fever in 2002. Jerry traded his Taipan 4.9 in to the local dealer for a used I-17R later that year. He was the one who said that he thought the I-17R is a superior boat to the T4.9, especially when it came to single-handed spinnaker sailing. Jerry is the only person I know who has owned and raced both boats.
