A new group that has stepped in to take over hydroplane races in Coeur d’Alene says it plans to hold the Coeur d’Alene Silver Cup in mid-July, the weekend before teams compete in the Gold Cup in the Tri-Cities and two weeks before the Seafair races in Seattle. The Coeur d’Alene Hydroplane Regatta, now affiliated with the race sanctioning organization H1 Unlimited, had been looking at mid-August for the races but has settled on July 17-19, said Keith Allen, the group’s general manager. The date change “allows for three consecutive weeks of H1 Unlimited Hydroplane Racing in the Northwest” and avoids conflict with another lake event in mid-August, Allen said Friday. H1 Unlimited recently signed an agreement with Silver Cup organizers to stage unlimited hydroplane races on Lake Coeur d’Alene this summer/Scott Maben, SR.
