Alinghi said Monday they would not go back on hotly contested rule changes which the Swiss syndicate plan to introduce for the next event scheduled for 2009 in Valencia.

"We have no intention of going back (on decisions that have been taken)," Michel Hodara, the chief operating officer of America's Cup Management (ACM), set up by Alinghi to organize the yacht race, told AFP.

Italian syndicate Mascalzone Latino has also urged a compromise solution on Friday to resolve the impasse. Mascalzone owner Vincente Onorato suggested not changing for 2009 the America's Cup Class yachts used this year but to move to the larger format Alinghi proposes for the following edition after that.

The compromise solution was rejected by Hodara, who said the teams which take part 2009 Cup would get information on the characteristics of the new boats from September 15, ahead of an October 31 deadline.

"It is a shame that people could think that things would not be carried out in a fair and just way," said Hodara.
