Thames river rage drama ends with huge fine

Boat-owner that caused Kingston Regatta incident charged more than 拢4,000. Video evidence shows disgraceful behaviour on the water.

Boat-owner fined for "disgraceful" behaviour during Thames regatta

An appalling incident of river rage on the River Thames at Kingston-upon-Thames in July 2024 has ended with 拢4,334.54 in fines, compensation and costs at Staines magistrates鈥 court on 28 January 2025.

The perpetrator had navigated his boat dangerously and used abusive language at other river users. He was also found guilty of obstructing a boat race and interfering with the safety of persons gathered, failing to comply with a harbour master鈥檚 notice, and failing to register his boat for use on the Thames.听聽

Scott Keen, of Morden, Surrey, steered his boat, Barney McGrew, along the Thames into a closed area of the river being used for Kingston Amateur Regatta, an event established in 1852, narrowly avoiding colliding with and swamping rowers.听聽

Foul-mouth tirade

The court heard how Keen was advised by an umpire that the river ahead was closed and he should return to a navigation channel. He ignored the request and continued past the umpire, cutting across the racing line and narrowly missing one of the boats, which had to take last-minute evasive action to avoid a collision. His cruiser than caught the anchor rope of a race stake boat, before he stopped and launched a foul-mouthed tirade against participants, yelling that 鈥榯hey did not own the (expletive) water.鈥櫬犅

His actions and the way he navigated his vessel endangered the safety of those present at the Regatta, included young scullers in rowing boats. An eyewitness captured the full extent of the drama on a mobile phone.听

Environment Agency officers carried out a detailed investigation into the incident and discovered that Barney McGrew was also an unregistered vessel. Keen was invited to a voluntary interview but failed to attend. A summons was subsequently issued for his appearance at Staines magistrates鈥 court on 28 January 2025. Again, he failed to attend.听

Incident 鈥榳as a disgrace鈥

Maria Herlihy, operations manager at the Environment Agency and harbour master of the Thames, said:

鈥淭his incident was a disgrace. Keen showed no regard for the safety of other river users and could easily have caused a tragedy. Quite frankly, it was no surprise to discover that his boat was unregistered, and we are happy with the court result.

鈥淲e hope that this serves as a clear warning to all 鈥 anti-social and dangerous behaviour on our rivers will not be tolerated, and we will take robust action to deal with those who disregard the rules and regulations for boating on the River Thames.鈥澛

The magistrates fined Keen the maximum penalty of 拢1,000 for interfering with the boat race and navigating his boat without due care and attention. The court explained that it used its discretion to go outside the sentencing guidelines to deal with the matter robustly.

The court heard the incident was shocking in its totality, with clear criminality that endangered the safety of other people, including the young people involved in the regatta.

The court also complimented the Environment Agency鈥檚 investigation, and the evidence submitted.听聽

Also charged in court, on the same day, for separate and unrelated incidents was Paul Campbell of West Molesey, who was found guilty in his absence of having not registered his boat, Enigma, for 2024 and failing to comply with directions to move his vessel from its location at West Molesey riverbank. He received a total of 拢2024.24 in fines, compensation and costs to be paid within 28 days.

Ms Herlihy added:

鈥淎s these prosecutions show, we have no hesitation in bringing offenders to court who avoid their obligations and responsibilities to lawful river users. Just one day in court has resulted in more than 拢6,000 of fines and compensation, which should serve as a major deterrent.鈥澛

Last year鈥檚 crackdown on unregistered vessels in the Thames resulted in 40 boaters having to pay a combined total of over 拢55,000 for their offences.听

Renewal invitation letters for 2025 registrations on the River Thames were sent in November last year to everyone that registered their boat in 2024, and owners were encouraged to register early to ensure their boats were compliant by 1 January when the new season began.听聽

The Environment Agency鈥檚 approach to non-registration on the Thames has changed 鈥 boat owners are given ample opportunity to register their boat. However, once a summons has been issued, it won鈥檛 stop court proceedings, even if the boat owner subsequently pays their registration fee.听

Similar to excise duty for road vehicles, boat registration fees allow the Environment Agency to manage and maintain more than 600 miles of inland waterways across England, keeping them open and safe for thousands of boaters to enjoy.听
