Seems reasonable to me as a sign of respect to the previous incidents :
Australian Sailing (AS) Prescriptions and Special Regulations Part 1 Category 6 shall apply, modified as follows:
a) Cl 3.12 Pulpits, Stanchions and Lifelines for Category 4 shall apply.
b) Cl 3.14 Toe Rail or Foot-Stop for Category 4 shall apply.
c) Cl 3.24.3 through Cl 3.24.9 Engines for Category 5 shall apply. "
Compulsory life lines on an Adams 10 is a real pain. Due to the geometry of that particular boat it is really hard to sail well without getting the sheets caught. The stanchions probably get bent after a race or two any away. The Adams 10 boats without life lines in RMYS and RYCV are pretty competitive. It is a shame to exclude them and I can understand how this exclusion is interpreted as a act of war.
I thought this was a thread about big boats ?
