Bridging the gap between road and deep water.
GEM Marine Services Ltd operates a road-transportable Highfield Patrol 700 RIB across the United Kingdom. Available for bare boat charter, crewed safety boat operations and — with our full survey suite installed — CAT A hydrographic survey work.

Bare Boat Hire
Professional-grade Highfield Patrol 700 charter for qualified operators. Mobilised by road to your launch site of choice across the UK.
Crewed Safety Boat
Experienced helm and crew supplied for marine civils, dive support, film, events and offshore project safety standby duties.
Hydrographic Work
Optional full survey suite installed and operated by partnered CAT A Surveyors for bathymetric and sub-surface data acquisition.
Mobilised by road.
Deployed by intelligence.
Our trailer-launched Patrol 700 bypasses the constraints of fixed-port logistics. Shallow draft, high-spec road transport and rapid mobilisation mean we reach launch sites larger vessels can't — anywhere from the South Coast to the Hebrides.

Based on the River Medway, Kent.
Our home port is Chatham Marina, with immediate access to the Medway estuary, the Thames Estuary and the wider South East coast. From here we mobilise UK-wide by road within hours.

Safety Boat Standby
Crewed cover for marine construction, offshore renewables, dive operations, regattas and on-water filming.

Hydrographic Survey
Full survey suite installation, paired with CAT A Surveyors for IHO-compliant bathymetric data capture and reporting.
