Adam Russell (28), of Murrays Mew, Burton, Milford Haven, was sentenced at Swansea Crown Court today (22 January 2026) over a life-threatening incident which took place on 11 August 2024 on the River Cleddau.
In addition to the suspended prison term, Russell must complete 15 hours of required activity; 200 hours unpaid work; and pay his victim a total of £1,676 in compensation for damage to property and personal injury, plus £3,000 prosecution costs.
It is the first prosecution under the Merchant Shipping (Watercraft) Order 2023, introduced in 2024 to empower prosecution of anyone who puts others at risk by using powered watercraft of any size in a dangerous manner, including small motorboats and jet skis.
Swansea Crown Court heard how the crash near Milford Haven wrecked the teenage boy’s one-person kayak and left him with cuts and bruising to his arms and lower lip.
The young man has not returned to water sports since, describing the experience in his witness statement as “terrifying”.
Moments before the impact, Russell had been seated steering a single-engine, duo-prop speedboat, White Mischief, upstream at unsafe speeds of up to 25mph which lifted the bow and obscured his vision. He was carrying six passengers, including children.
Coming in the opposite direction was the 15-year-old victim, in a group with his father and friends in brightly coloured kayaks and wearing red personal floatation devices.
The young kayaker spotted Russell’s vessel approaching near Rudders Boatyard, an area Russell was familiar with and which is known as a busy location for moorings and leisure activities.
The teenager tried to paddle out of the way but, unable to see the danger, Russell changed course and struck the kayak, driving over the victim and throwing him into the water.
The MCA led the prosecution with support from Dyfed Powys Police and Milford Haven Port Authority.
Judge Geraint Walters said
Just like our roads, our seas and our rivers are not playgrounds. They are required by all of us to recognise the risk to others innocently going about their business.
MCA Investigator Paul Atkins said
This case shows the importance of keeping a proper lookout and operating safely. It was a very close call – if circumstances had been only slightly different, there could have been a terrible tragedy.
This prosecution, the first under new watercraft safety laws, sends a clear signal that people flouting the requirements that keep us all safe on the water are liable to be held accountable for their actions.
Mike Ryan, Harbourmaster at the Port of Milford Haven, said
The incident on the Milford Haven Waterway was extraordinarily dangerous with a very real threat to life, yet it was also completely avoidable.
We support the MCA’s decision to prosecute the defendant for failing to keep an effective lookout. It is an important reminder that not only do Waterway users have a responsibility to keep themselves and any passengers safe, but also a responsibility towards every other user of the Waterway.
Keeping watch is one of the most important aspects of staying safe afloat look ahead, look behind and look left and right, adjust your speed as necessary and take early, clear and decisive action to avoid collisions.
Background
Russell was sentenced having previously admitted two charges at Haverfordwest Magistrates’ Court on 2 December 2025
-
failing without reasonable excuse to prevent the loss or destruction of another watercraft and/or serious injury to another person, contrary to Section 6 of the Merchant Shipping (Watercraft) Order 2023.
-
failing without reasonable excuse to comply with the International Regulations for Preventing Collisions at Sea 1972 (COLREGS), namely failing to adhere to Rule 5 (look out), Rule 6 (safe speed) and Rule 7 (risk of collision), contrary to Section 6 of The Merchant Shipping (Distress Signals and Prevention of Collisions) Regulations 1996.
Russell became the first person to face prosecution in court under the Merchant Shipping (Watercraft) Order 2023. It was used previously in 2024 to caution a jet ski rider.
An order was made in court to restrict reporting of the victim’s identity.
