Produce a practical, multiple-role STOL electric aircraft maximizing its relevance and appeal across market segments

Deliver our mission with sustainability as its core driver

Embed our SEA design values so as to remain flexible and entrench Safety, Efficiency and Adaptability both within the design process and resultant aircraft

Do not ‘reinvent the wheel’, but improve on historic design deficits, incrementally where feasible

Use proven, certified systems and solutions wherever sensible and practicable

Avoid unnecessary complication, leave the design of ‘exotic’, revolutionary, new aerial transport platforms to those with deep pockets and stakeholders to keep convinced of their vision

Minimize reliance on ‘known unknowns’, i.e. except where necessary, do not incorporate concepts that are either under development or require standards to be developed for them – or both

Reduce risk through deferring strategic decisions to allow any ‘known unknowns’ to mature, ideally into ‘known knowns’, without impeding progress

SEA design values

As we move into an era of sustainable general aviation, Cormorant presents an innovative aircraft that addresses general aviation design deficits. This is particularly so in its easily configured amphibious format, where many dated configurations in this sector can be traced back seventy years or more.

Central to Cormorant’s design philosophy are its SEA values, hence our corporate name – Cormorant SEAplanes:

  • In-line, low center of gravity yields improved maneuverability and stability.
  • Enclosed, ducted fan results in safer operation.
  • Fuselage design has in-built lift characteristics, enhancing STOL performance.
  • Ducted fan provides enhanced performance including, greater thrust, higher efficiency, and quieter operation.
  • Composite material construction emphasizes low mass whilst enhancing structural integrity, reducing operating and maintenance costs.
  • Integrated solar panels minimize reliance on charging infrastructure.
  • Internally, the cabin space is both roomy and reconfigurable to adapt to a variety of operator requirements.
  • Externally, Cormorant provides for unique, easy ‘reconfigurability’. The simple attachment of our boat-hull transforms an efficient, multi-use, land-based aircraft into a high-performance, amphibious seaplane.
