New PLA Trainee Marine Pilots

We’re delighted to welcome Lloyd, John and Alfie to the Port of London Authority as they begin their journey as trainee marine pilots. Each brings with them a wealth of experience, a deep commitment to maritime safety, and a shared passion for ship handling and navigation. The Thames is one of the most dynamic and challenging pilotage environments in the world, and we’re confident they will rise to the occasion.

Lloyd Mason

Originally from Dover, Lloyd Mason began his maritime career as a cadet with P&O Ferries, working on routes between Dover–Calais and Hull–Rotterdam. He spent four years as a Second Mate in Dover before moving to New Zealand, where he worked for eight years as Second Mate and two years as Chief Officer with Interislander. He also served as Mate for two months with the Shetland Islands ferries. 

Lloyd has aspired to be a pilot since his cadetship. His decision to return to the UK was driven by a desire to be closer to family and spend more time with his children. He is particularly excited about the ship handling aspects of the role. Outside of work, he enjoys mountain biking and hiking. 

John Cassidy

Originally from Liverpool, John Cassidy has over 15 years of experience in the marine industry. He has worked on a wide range of vessels including container ships, tankers, and most recently, tugs. Throughout his career, he has developed a strong and varied skill set, with becoming a PLA trainee pilot marking a proud milestone. 

John sees pilotage as the pinnacle of a seafaring career—one that offers both challenge and immense job satisfaction. He is particularly excited about being a key part of the bridge team, working on a variety of vessels, and mastering ship handling on the Thames. Outside of work, John enjoys hiking, climbing, golf, reading, and travelling. 

Alfie Gude

Originally from Grimsby, Alfie Gude has spent over 14 years in the maritime industry, working on a broad range of vessel types including ROPAX ferries, harbour tugs, tankers, dry bulk carriers, and RORO vessels across Australia and internationally. He has held roles from cadet through to Chief Officer and Relief Master, with particular strengths in ship handling, crisis management, and safety leadership. 

Alfie has also worked as a maritime safety consultant for major clients including BHP, Rio Tinto, and the Australian Antarctic Division. Drawn to the unique challenges of the Thames, he sees pilotage with the PLA as a professional milestone. He is excited to join a world-class team and continue developing his skills in one of the most demanding pilotage environments. Outside of work, Alfie enjoys rugby, road cycling, clay target shooting, and spending time outdoors with his wife and children.
