RedactedNarrative: On 9/5/15 at approximately 3:00pm Operator1 was traveling in his 1989 Sea Sprite (HIN # SSBA9071H889) with his wife and 3 children. They were heading west on the Calumet river at approximately traveling at approximately 20 mph. Operator1 noticed three people riding personal watercraft (PWC) behind him start using his wake to jump their respective PWC''s. Operator1 realized this and began to ensure he was aware the location of each of the PWC''s. 
   
  One of the PWC''s driven by Operator2 approached from Operator1''s port side of the boat at a high rate of speed hitting the wake and then hitting the stern side of the boat. Operator2 was thrown from his PWC and Operator1 stopped immediately to ensure everyone was ok and assess any possible damage to his boat. Operator1 noticed damage to the swim ladder and some fiberglass damage to the rear of the boat. Operator2''s PWC appeared to have minimal damage. Operator1 and Operator2 stopped to exchange information; the PWC was an older Tiger Shark with no registration Operator2 claimed he did have coverage with Progressive Insurance Company. Operator1 noticed a vibration in the rear of his boat as he returned to the boat launch. 
   
  Operator1 was unreachable due to work issues and could not get the damage estimate until over a month after the accident. CPO met with Operator2 and was told he purchased the PWC via Craigslist (seller unreachable) for $200. Operator2 was issued a citation for unnumbered watercraft.
