Coast Guard Proposes Safety Zone for Ironman 70.3 Ohio in Sandusky Bay

The Coast Guard is proposing a rule to establish a recurring safety zone for the annual IRONMAN 70.3 Ohio race. The proposal would add the event to the list of regulated marine events in the Detroit Captain of the Port zone.

Why it matters: This action is primarily administrative, formalizing a safety measure for a recurring annual event. The Coast Guard certified that the rule would not have a significant economic impact on small entities. The practical result is that boaters in Sandusky Bay will need to account for a one-day closure in July and may need to contact the Coast Guard to transit through the swim course area.

Who it affects

• Boaters and recreational vessel operators in Sandusky Bay who may encounter a one-day closure in July.
