DAY 5-THE FLEET TIGHTENS UPThe fleet at the Audi Etchells World Championships off Fremantle, Western Australia, celebrated the start of the second half of the regatta by closing up the rankings dramatically. America's Cup legend John Bertrand scored his first win of the series, which moved him up from seventh to fifth on the leaderboard, While San Francisco skipper Craig Healy had his second good result, with a third place, which moves him up from 24th to 17th.However, a very happy Healy stands to make a big jump up the ladder when the discard kicks in, after tomorrow's sixth race, when he can drop an OCS from his scoreline.Sandwiched between Bertrand and Healy on the finishing line today was Australian skipper Cameron Miles, a former world champion, who also has Phil Smidmore as his mainsheet man, one of John Bertrand's Cup winning Australia II crew.Jud Smith, of Marblehead, Mass., is clinging to a much reduced lead in the series, with England's Ante Razmilovic closing to within four points of the top spot after backing up yesterday's win with a fourth today. With a solid 18 to 20 knots of seabreeze today, Smith struggled in the more robust conditions, finishing 21st after rounding the first mark in 18th place.Level, three points further back are New Zealander Alastair Gair, and Briton Andy Beadsworth, with the Kiwis finishing a consistent sixth, while Beadsworth, like Jud Smith had a bad one, finishing 19th, though anywhere in the top twenty in this fleet is a success. Whereas earlier in the series, after three races, there was 25 points between first and third, that differential takes in the first seven places now.Commenting on his win today, and the intensity of the competition, John Bertrand said, "it's really dicey coming off the line, the difference between breaking through the so-called bubble or being absorbed back into the fleet, is like the thickness of a hair, and we were just able to slowly develop our own lane. The racing is really, really close, very tight, and very sophisticated in terms of differentials in boatspeed."Craig Healy led around the first mark, but confessed to losing the lead to Bertrand on the first downwind leg because, "we got our wind messed up, and we didn't help ourselves." From then on he battled all the way with Cameron Miles describing the final leg saying, "we were chewing on him a little bit, and we thought, 'This is possible, we can get these guys.' We had a plan, carried it out, and came within six feet of getting them."For Healy this is his third time sailing in Fremantle, having been navigator with Tom Blackaller and Paul Cayard on USA in the '86/'87 America's Cup, and before that in a Laser worlds back in about '78.
