Dave White reports on the 505 world's championship in San Francisco and the continuing American dominance.

The 26th world championship regattas were sponsored by the St Francis Yacht Club and the combined fleets of San Francisco Bay between 3 and 15 October. The St Francis Yacht Club is close by the Golden Gate bridge on the southern bank of San Francisco Bay. To get to the course area competitors could elect to sail or be towed the eight miles past Alcatraz island to the Berkeley shore.

The course area, known as the Berkeley Circle, is an area of fairly shallow water with very little current flow. On most days the first of the sea breeze would reach the circle by about noon and by 1300 it would be fairly settled in strength and direction so that races could be started on schedule. The wind was invariably in the western quarter and some days it was accompanied by a short chop. When the wind did shift it
tended to shift over the whole course area rather than locally. Therefore it usually paid to go to one corner or the other. Mostly it paid to go right, but sometimes it paid to go left and there was no telling which was going to be best. On the runs the same tactics of going to the corners paid off against running square. It definitely did not pay to go up the middle, because although it was possible to make gains against those boats that chose the wrong corner, it seemed that the majority of the fleet did invariably find the right corner.

The first two races were won in fine style by Jorgen Schonherr of Denmark. In the first race he was squeezed at the start by Peter Colclough and had to tack off behind probably half the fleet. This took him to the favoured, right side of the course and he was first around the mark and away to an unassailable lead. Americans Surtees and Benjamin were second and third.

In the second race Schonherr made a good early start out of the gate and crossed the majority of the fleet to get to the right and again lead the fleet. In this race the wind was stronger than the previous day and he was pushed hard by America's Bixby and defending champion Benjamin. The latter had a gear failure (after the time he spends on his boat? Editor remark) when challenging for the lead and fell back to finish 16th. Andron who had won two races in strong winds in the Pacifics, moved up well to finish third behind Bixby.

The third race saw a change in the pattern and the left side of the course was best on the first leg. Bruniges of Australia led early on, but Bixby came through on the run by gybing away and going to the opposite corner from the leaders. The strongish winds again brought the same boat into the leading positions. Benjamin was second and Schonherr's third place made him an impressive series leader at the halfway stage.

Race four was started in very light winds from an unusual direction, the south. Those out of the gate early did best and Benjamin led from Colclough and Dave White at the first mark. The next leg saw the wind swing right round to the north and this turned the race into a lottery for most of the fleet. But the decision to abandon was a bitter blow for the leaders Benjamin, Colclough and White.

In the rerun Bixby with the giant Cam Lewis on the wire was an easy winner in the strong force 5 winds. Benjamin did well by setting his spinnaker on the first reach when no-one in front did. It was a desparate measure and Benji moved up from the mid-twenties to finish second. Larry Tuttle of the US was third.

Myuky Kai of Japan turned the form book upside down by winning the fifth race after a previous best place of 31. A strong breeze from the left side of the course thrust him into the lead at the first mark. Kai held his position inspite of huge fluctuations in wind strength and Steve Benjamin's superb effort failed by just inches on the finish line. It was reckoned that those inches could decide the title as Bixby's third place meant a margin of six points separated him from Benjamin with Bixby having the better discard. Schonherr had not maintained his early lead in these last two races, but Olympic points scoring meant that he could win the championship by winning the last race with Bixby below 16th place and Benjamin below 10th. This meant that the Americans could not afford to get involved with too much infighting. An added ingredient was that Bixby had protested Benjamin unsuccessfuly for a sail change after the five minute gun in an earlier race.

The start of the final race was dramatic indeed with the two Americans circling around, each intent on scoring a foul against the other before the gate boat reached them. In the event they both got away cleanly with the ultra-aggressive Benjamin having the upper hand. Schonherr was buried in the middle of the fleet and had lost his chance but Bixby was hanging on to his rival's transom.

At the last mark Benji was winning the championship by one point but Bixby gained three places on the beat to the finish while Benjamin could only gain one. This gave Bixby and Lewis the championship by two points. The duel for the championship in this last race tended to overshadow what was, nevertheless, a good performance by Peter Colclough who pulled up from eighth position at the first mark to score a fine victory.

Bixby and Lewis' performance was impressive indeed. They had come to San Francisco weeks ahead of the rest of us. They had been sailing the circle virtually every day and very soon this aspect of their preparation became apparent. They convincingly won the Pacific championship which was held over three days prior to the worlds. Benjamin was not quite as well prepared as is evident from his gear failure in race two.

Bixby was using a two seasons old Lindsey hull with Tuttle foils. His jib tack was on the bow with no spinnaker shute and he had the facility to lift his gybing board, vertically. This of course meant that he could stop it gybing in strong winds. Bixby is a sailmaker with the Hood one design loft at Marblehead. He set his sails on a mast of carbon fibre and epoxy construction. It was of smaller section than conventional masts and the weight saving was reputedly two or three pounds. His shrouds and trapezes were located at spinnaker sheave height as is favoured by many of the American boats. Their hounds are generally lower than ours and this enables them to use a lot of rig tension without the accompanying prebend.

Each day before the race Bixby and Lewis could be seen applying a coating of polymer to the underside of their hypocritically named boat "Complex chemicals kill". Some people were of the opinion that this would wash off before they reached the course area. Others said that they could still feel it on the boat at the end of the day. Perhaps it is coincidental, but the top two boats used this trick.

Benjamin's boat was the same one which he used in Hayling Island last year. Like Bixby he uses no shute and his jib tack is well forward on the bow. His ability to move the shroud attachment points on runners gives him very good rig control. He is a brilliant sailor, very aggressive on the water but gear failure probably cost him the worlds. Schonherr's boat was a two-seasons old Parker. He also had no shute and the forward jib tack. His jib, which was his own make, was one of the fullest in the fleet. And he used a Number One main and his own design of spinnaker.

An interesting feature on this boat was the rectangular plywood and balsa box which was used to exclude water from the centreboard case. It slotted onto a bolt in the back of the case so that it could pivot up out of the way of the centreboard when raised. Schonherr claimed that he could get rid of four litres of water � a saving of 8.8 lbs (approx 4kg).

So what are the lessons to be learned from this championship? The fact is that the Americans have made steady technical advances over the past few years that have put them in the forefront of 505 yachting worldwide. It has to be said that this has been achieved at no little cost but in this regatta they had six boats in the top 10 and 10 in the top 20. Techniques which are standard on their boats such as stuff-luff jibs and gybing centreboards are not widely used in other fleets. For instance, the second best nation, the Australians do not use gybing boards. Also several of our top boats still favour fixed boards and none of us have the cunningham control on the jib.

Our boats seem to be over simplified by comparison with what the Americans regard as necessities by way of control systems. Their approach to this event was more professional and the results show it.
