Seahorse Amphibious Vehicles

What Seahorse Amphibious Vehicles does

Seahorse Amphibious Vehicles is a UK-based, family-owned manufacturer that designs, builds, and globally exports the MK5 — the world's only fully electric amphibious passenger vehicle (APV), with a hybrid variant also available. Founded in 2012 by Graham Lumley (co-founder Ed Lumley), the company spent a decade in R&D before bringing the MK5 to full production in 2022. The vehicle is built in-house at a specialist facility near Heathrow Airport, with design led by a team of nautical engineers and buoyancy experts located just outside London. Technical features include proprietary rim drive water propulsion, Glass Reinforced Plastic (GRP) hull construction, a high-capacity battery enabling full-day operation on a single charge, military-grade axles, and seven watertight compartments designed to meet the highest international safety standards.

The business operates a direct-to-operator, bespoke manufacturing model with no resellers or distributors. Each vehicle is tailored to the customer's country-specific regulatory requirements, branding, and optional extras, with pricing provided on a quote basis under multi-year contracts. Beyond hardware sales, Seahorse offers an integrated end-to-end service covering onboarding, certification guidance, bespoke design, crew training, launch planning, marketing support, and aftersales — leveraging 14+ years of operating experience. The company targets both established tour operators and new entrants in the amphibious tour market, with current vehicle operations in Windsor, Liverpool, London, South Africa, and Singapore through approximately 7 global partners. Revenue is derived from vehicle hardware sales and professional services, with no public pricing, no disclosed funding rounds, and an estimated ~9 employees. Marketing is conducted via direct contact, a content-rich website, LinkedIn, and Instagram.
