Safety measures include a 30-foot fire lane and 14 operational fire pumps along the docks for emergency response.\n\nIn-water fabrication and installation of the planned dock design will begin on June 8, 2026, and will be completed by June 17, 2026. The event dates for the vessel display are June 11–14, 2026. Immediately after the boat show ends, fire lanes will be reopened, docks will be removed, exhibitor boats will exit, and marina tenants will return. Docks will be transported back to the splash out location and removed in the same manner as installation.\n\nThe operation will take place at Safe Harbor Sunroad Marina Docks K, L, & M, located at approximately 32.72644° N, -117.18881° W (degree decimal format).\n\nMultiple vessels will be docked on Docks K, L, & M within Safe Harbor Sunroad Marina.
