Witnesses told Nampa police that two motorcycles were racing at speeds up to 100 mph before one of them crashed into a parked boat along South Powerline Road Thursday night. The speed limit on the two-lane road is 35 mph.

The motorcyclist and the owner of the boat — who was struck by the motorcycle as he tried to jump into his vehicle — were both taken to a local hospital. Their names have not been released, and Nampa Police Sgt. Mike Wagoner did not know their status Friday morning.

The boat owner sustained minor injuries, officials said, and the motorcyclist’s injuries were not life-threatening.

The second motorcyclist did not stop. Police said they identified — but had not located — that person Friday night.

The crash happened in the 500 block of South Powerline Road in Nampa.

The motorcycles were traveling north. One of the motorcycles struck the back of a boat attached to a truck parked on the east side of Powerline.

The driver of the bike, a 32-year-old male from Nampa, was thrown from the bike into the street. The owner of the truck and boat was standing next to the truck when the crash occurred, and he was unable to get into his vehicle before being struck by the motorcycle.

Wagoner said the team investigating the crash are not working Friday, and he did not have any additional information about the crash.

"We have to reconstruct the crash itself and figure out how everything happened," he said.
