A bow thruster is a transversal propulsion device installed in the forward (bow) section of a ship, allowing it to move laterally (sideways) without forward motion. It is especially valuable for low-speed maneuvers such as berthing, unberthing, or holding position in dynamic positioning (DP) systems. While it greatly aids ship handling, it comes with several limitations.

The bow thruster was first developed in the mid-20th century to improve low-speed maneuverability in increasingly larger ships. Early versions appeared in the 1950s and 1960s, particularly on Scandinavian ferries, using simple mechanically driven side propellers. By the 1970s, tunnel-type bow thrusters became standard on tankers, ferries, and cruise ships, often powered by diesel or electric motors.

Barry discusses the humble bow thruster - how it is measured, some of the limitations and gives real world accounts of when the thruster may let you down.

When a pilot steps on board, two experts meet—each with a distinct role and vital knowledge. But how well that knowledge is shared can mean the difference between a smooth berthing and a costly incident. Whether you're a seasoned master mariner, an experienced pilot, or just starting your journey at sea, this blog unpacks the procedures, challenges, and real-world lessons behind effective communication on the bridge.

The MPX is not just a formality. It is a structured, safety-critical process that ensures mutual understanding between the ship's master and the pilot regarding the voyage plan, vessel characteristics, operational constraints, local conditions, and potential hazards. It is where bridge resource management meets local knowledge — and where effective communication can prevent misunderstanding, delay, or incident.

But beyond the technical requirements of the MPX lies a deeper connection - the mutual respect and understanding fostered by two professionals drawing on each other’s knowledge to overcome critical safety hurdles - when done properly the pilot can become the Master’s aide - allowing him or her to seek professional opinion or just vents about onboard challenges. A good pilot is not just a good assistant, but a sound and dependable maritime friend.

Barry discusses this relationship and how during his 25 years pilot career he has advised Masters beyond the passage planning, ship handling and navigational spheres.

The global shipping industry is responsible for transporting over 80% of world trade by volume, but it also contributes significantly to greenhouse gas (GHG) emissions. In response to environmental concerns, the International Maritime Organization (IMO) has introduced various measures to reduce the carbon footprint of ships. Among the most critical are the Energy Efficiency Design Index (EEDI) and the Energy Efficiency Existing Ship Index (EEXI).These indices form a key part of the IMO's strategy to reduce GHG emissions from international shipping and support the goals of the Paris Agreement.

Barry goes over the history of International response to global warming, how shipping contributes to it and what the IMO concluded in April 2025 was the way forward to combat it. Could the Marine Equivalent of carbon credits work internationally and be the silver bullet the indutry dreams of?
