Frequently Asked Questions

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

Due to Africa’s current Rescue facilities available to inland water traffic, our vessels are designed and constructed in light weight MGA to be unsinkable. Our design includes buoyancy cells incorporated in each of the MODCAT’s eight independent watertight compartments. These in turn are each fitted with independent bilge pump systems. This provides passengers and operators with a safe platform that will sustain them in the event of the vessel's sponsons being compromised in any way.

Today most Marine Boat Builders can provide an alloy vessel for about the same cost as one in steel, provided painting of the hull is not required, except for below the waterline. Our platforms provide a vast amount of deck space at highly cost effective real estate rates.

The lightweight platform of the MODCAT design offers drastically reduced fuel requirements and overall operating costs.

Our range of MODCAT modules are provided with surfaces that are not painted and will require minimal maintenance. Repairs to sponsons or pontoons are easily done in remote locations with replacement panels being provided from our factory as pre-formed and ready to weld.

Should clients need their vessel painted, if properly done; the paint system will not be any more trouble than maintaining a fiberglass boat, and less than a steel vessel.

An aluminium boat will have a much higher resale value than a steel boat, allowing any minor difference in original acquisition cost to be more than recovered after the MODCATs extended service lifespan.

Aluminium vessels are between 40% and 60% lighter than GRP and Steel equivalents respectively, which in a larger vessel results in less displacement, a smaller engine requirement and greater range. Another distinct advantage is that reduced vessel dead-weight provides us with an exceptionally shallow draft, which in turn, extends the MODCAT’s shallow draft service range to areas with 300mm - 375mm of water, and allows for simple beaching and backing off at safe landing areas.

These vessels come in various sizes and the load and number of passengers the vessels can carry depends on the vessel selected. Details on the vessels load and carrying capacity can be obtained from our website.

Lighter weight build materials being utilized for a strong platform structure allows owners to increase fuel, range and cargo capacity.

Aluminium, being a lighter material permits our Design Team to place weight lower down in the Sponson design, allowing for stable weight distribution to support the platforms deck equipment layout.

The design provides exceptional structural integrity, with no compromise in materials or welding standards for vessels in this classification. Propriety design features included, are our deck and sponson sub-assembly mountings, which were verified against exhaustive stress, and strength analysis. 

As an example, recently a 1200 MODCAT OPL Platform after being inverted, remained afloat with two 5 ton mooring blocks secured to the deck and needed only electrical repairs to resume service within a week.

Clients are in a position to extend the platform’s hull and deck area, by acquiring additional sponson and deck modules.

MODCAT's need modest horsepower to propel them efficiently. The MODCAT sponson design incorporates numerous vectored planing surfaces, which enable the vessel to operate at lower speeds to achieve maximum fuel efficiency during operation, which by implication prolongs the motors service lifecycle, and reduces maintenance costs.

The vessel is designed to operate in draft of less than 400 mm and the twin propulsion options available, greatly enhance the manoeuvrability of the vessel for close quarter and restrictive navigation situations that may arise during operations.

MODCAT's can be supplied as integrated modules, which allow for shipping from our works to the clients site by utilizing standard ISO containers or trucks, thereby saving on shipping and clearing costs. 

MODCAT sponsons are available in symmetrical and asymmetrical options, as our sponson design is tailored to the platforms operational requirements, and intended sea conditions within its theatre of operations.

MODCAT's by virtue of their design, can be assembled and deployed in remote areas and after project completion, disassembled and loaded into their shipping containers and relocated or securely stored until they are required for further deployment and use.

The SML 1200 has been specifically designed to operate offshore in conditions of up to sea-state 5 while catering to the needs of the Environmental, OPL, and the Oil & Gas industries.

The hull and fabrication thereof will be covered by Legacy Marine Group’s Standard 12-month HDB Warranty against any construction defects or defective workmanship.

Propulsion Units, Electronics, Navigation Equipment and all other items fitted to the hull are covered by a direct original Supplier’s OEM Warrantee from date of acquisition.

LMG has authorised Dealers / Representatives throughout Africa who could assist with your purchase, however where there is no representation, you are welcome to contact our Sales Department situated in Port Elizabeth directly who will arrange to have the vessel shipped to your deployment site.

  • Standard Double Deck MODCAT 1200 can be completed in 24 – 28* weeks.

*All reflected lead times are dependent upon factory build demand at the time of order placement.

The vessel has been designed to operate in and satisfy the following industries in a variety of applications:

  • Transportation
  • Tourism
  • Aquaculture
  • Mining
  • Construction
  • Cargo
  • Medical Services
  • Environmental
  • OPL
  • Survey
  • Dive Support
  • Houseboat
  • Hospitality

The MODCAT vessels are built with standard engine out-mounts and clients can fit their own motors to the vessel if they wish to.

The vessels are designed with a large amount of deck space which would make it feasible to add components, however it is essential to contact the Design Office in order to determine the impact that the applicable additions may have on stability, centre of gravity and payload capacity.
