Design banner showing the internal framework of the MODCAT modular platform


The initial prototype Modular Platform was developed by Gerry van Niekerk and Pieter van Heerden, resulting in the initial 6-meter platform, being launched to Zambia during 2005.


The vessels were provided as a safe option for passengers in remote areas where there was limited, or no rescue services to cover commercial marine operators.


The immediate success of these platforms evolved to our standard 6 and 12 meter platforms which provides clients with solutions towards the 24 meter LOA mark.

Design Characteristics

MODCAT's display the characteristics of a catamaran, needing modest horsepower, while carrying high payload in shallow water operating conditions with stability.


The sponson design incorporates vectored planing surfaces which allow the vessel to operate efficiently under load at lower speeds which effects fuel efficiency, and service costs. The design has been subjected to exhaustive offshore testing and has achieved proven reliability, safety and durability.


MODCAT's operate efficiently with outboard or inboard propulsion options, while leaving a very low wake footprint for operations in environmentally sensitive areas.

Platform Scalability

MODCAT's are specifically designed to save weight, and deliver on strength and durability, and come in these primary sizes.


Length (LOA)

MODCAT 600 5800 mm
MODCAT 900 9000 mm
MODCAT 1200 11800 mm
MODCAT 1500 15000 mm
MODCAT 1800 18000 mm
MODCAT 2400 24000 mm

Standard MODCAT Sponsons and deck assemblies are all compatible allowing our clients to retro- or refit vessels by simple upgrade procedures on site.


Our Yard also design and incorporate above deck structures, which can be securely mounted onto the platform to meet client’s requirements.

Items such as Safety Railing, Passenger Seating, Bar etc. are costed according to client preference.

MODCAT superstructure design concept for maximum passenger capacity


Our designs have passed the stringent requirements of the South African Maritime Safety Authority (SAMSA) ensuring they are suitable for Commercial use and Passenger Transportation.

Our platforms are operational in both inland and offshore applications and can be build to Class society regulations, if, and when required.

Both Sponsons are divided into four watertight compartments and contain sufficient buoyancy material, to ensure the vessel stays afloat should either suffer collision impacts.

Additionally, each of the 8 watertight compartments is additionally fitted with a 600 GPH automatic bilge pump units centrally controlled from the wheelhouse.
