HIVE Underwriters Strengthens New Marine Platform with Duo of Senior Market Practitioners

Independent specialty MGA HIVE Underwriters (HIVE) today announces the appointment of two senior Marine underwriting practitioners to its new Marine specialty underwriting team. Both appointments are effective July 2026, on completion of their contractual obligations with respective current employers.

Alistair Marriott joins HIVE as Head of Marine, coming from Everest Insurance, where he most recently served as Deputy Head of Marine and Head of Cargo, International. A highly regarded market leader, Marriott brings extensive experience building and leading international marine and cargo teams, underwriting complex global portfolios and delivering disciplined, long-term performance.

Jared Short joins HIVE as Head of Transportation and Logistics. He was most recently Senior Underwriter – Logistics, Ports and Terminals at Markel International. Short is a recognised specialist in transportation and logistics risks, with a strong track record of leading underwriting teams and managing specialist, liability-driven portfolios across logistics, ports and terminals liability and property,  warehousekeepers’ liability, container lessor and operator risks, and shippers interest risks.

Alistair and Jared will join Nick Lewis, who joins as Marine CUO in July 2026 to lead the buildout of HIVE’s practitioner-led specialty marine underwriting operation.

Bruce Carman, CEO of HIVE Underwriters, said: “From the outset, our ambition in Marine is to build a business around exceptional, senior practitioners – people with the experience, judgement and leadership capability to build something meaningful and sustainable. Alistair and Jared are both extremely well known and well respected in the market, with strong reputations built on technical excellence and underwriting discipline.

Alistair and Jared have also worked together in previous roles and share a clear understanding of how successful Marine portfolios are built, led and grown. We are incredibly proud to attract this calibre of talent and to offer them the opportunity to build out a Marine operation at HIVE with real autonomy, aligned capacity and a long-term knowledge-led underwriting mindset.”

Alistair Marriott, HIVE Head of Marine, said: “HIVE’s approach to Marine is clearly differentiated; it’s about building a business properly, with the right people and resources, clear underwriting parameters and a strong focus on performance over the long term. The opportunity to work alongside a talented team at an independent, entrepreneurial MGA to help shape a Marine platform from the ground up is hugely compelling.”

Jared Short, HIVE Head of Transportation and Logistics, said: “Transportation and Logistics is a specialist class that rewards deep technical understanding and disciplined underwriting. HIVE’s commitment to practitioner-led underwriting and its willingness to invest in experienced teams creates a strong platform to build a portfolio that delivers consistent, sustainable returns. I’m excited to be part of that journey.”

HIVE’s Marine platform will focus on specialist niche segments within the class supported by strong data, aligned capacity and close broker partnerships. The expansion builds on HIVE’s established Aviation platform and its recent launch into Space, reinforcing its position as a focused, multi-line specialty MGA.
