Markel appoints Grant Smith to Director of Marine Transportation

Markel Insurance, the insurance operation within Markel Group Inc. (NYSE: MKL ), today announced the appointment of Grant Smith as Director of Marine Transportation at Markel International.

Smith will lead the development of the new Marine Transportation business, bringing together Markel International's Hull & Hull War, MECO, Marine & Energy Liabilities, and Transport & Logistics classes under a single leadership structure.

The move reflects the increasingly interconnected nature of marine and transportation risks and is designed to provide brokers and clients with more coordinated access to expertise across the portfolio.

In his new role, Smith will be responsible for shaping strategy across multiple classes and geographies while leading initiatives to strengthen underwriting capabilities, improve processes and support the delivery of tailored solutions for brokers and insureds.

He will also serve as a senior point of contact for brokers, clients and industry bodies, working closely with Claims and Actuarial teams to strengthen underwriting discipline and risk selection as risk exposures continue to evolve.

Based in London, Smith will report to Dan McCarthy, Managing Director – Marine, Energy & Construction.

Smith joined Markel in 2024 as Director – Marine & Energy Liabilities, before assuming responsibility for Transport & Logistics in 2025.

He has more than 17 years' experience across marine specialty lines and underwriting leadership roles.

McCarthy commented: "The marine transportation industry is facing heightened risk exposures, from increasing supply chain disruptions to rising thefts at ports as geopolitical tensions escalate worldwide.
