After all the heck-meck with the station 8/6 in the previous years the Americans decided to teach the Finn world a lesson and staged the 1983 Gold Cup in a pond in the back yard of the Harken brothers in front of the Milwaukee breweries. John Christianson was called back on duty to build the most perfect jig and there was no dispute about what is a Finn or not. Consequently the IFA decided to make the Christianson jig the standard for all future Finn measurement. In the first race the international jury disqualified four potential winners for infringement of rule 60 (Means of Propulsion) setting another standard of highest moral. Most of the races were sailed in light and shifty winds, veering with the sun. Only two races enjoyed fresh air. Without winning a single race Paul van Cleve, from the U.S. Navy, won the Cup in front of Wolfgang Gerz, who had two lsts but a 25th to count. Terry Neilson also with two victories collected a 33rd in the last race after a DSQ in the first, by going up the wrong side and lost. Mark Neeleman was another potential winner with a 14th as his discard.

Strong winds up to gale force characterised this world championship. Nice breezes during the measurement days were followed by days of storms, not allowing any race to be sailed. Five days of strong wind allowed 6 races, but on the last day the wind and waves were again too much. Terry Neilson, who was just behind Lasse, would have liked to sail again but Hjortnas found it to be too dangerous. The old man of the sea Jorgen Lindhardtsen aged 39 was leading overall up to race 4 but later collected 22nd and 20th and was finally third. For his mental son Lasse Hjortnas, 2/4/11/3/3 was good enough to win the Cup for the second time after 1982, just 0.3 points ahead of Terry Neilson. Larry Lemieux had some water in his double bottom in the beginning, but won two races after he took it out. Buzz Reynolds, who at the time of the Gold Cup thought he was to be the US representative for the Olympics damaged his best mast on the first day in the gale.

In contrast to all predictions the wind in Marstrand never increased above force 3 during this Gold Cup. The current was fairly strong. However nobody was able to read it, let alone predict it. Those who neglected it and did not worry about it had the best results. Everyday a different sailor was leading overall. Biased start lines required the severe sudden death five minute rule to be frequently applied and a number of favourites were disqualified. The jury was busy to grant a few additional DSQs. There was only one man, who finished six times among the top 6 boats, Khoperski, however one line honour was scored as PMS. The jury also gave a severe warning because of team sailing. At the beginning of the last race, four people still could have won the cup. Sobkowiak eliminated himself with a bold PMS under the five minute, rule.
