Rhino Marine Products (Pty) Ltd fabricates, markets and sells rigid, robust and reliable High Density Polyethylene (HDPE) boats.
The Rhino boats are fabricated primarily for use in the offshore and marine construction environments, the off-shore oil and gas industry, and for military use.
Rhino boats have been developed as a replacement to conventional RIB’s and have virtually indestructible HDPE hulls that are specifically designed to handle in tough commercial environments.
Rhino boats can be used for various applications, but our boats are primarily used as work boats, personnel transfer boats and scuba replacement boats (SRP). Our boats are supplied with petrol outboards or inboard diesel motors and our inboard versions can be supplied with water jet drive or Z-drive (stern drive) systems.
Rhino Marine Boats Advantages
Rhino Craft hulls require minimal maintenance and can be easily repaired or adapted by relatively unskilled staff.
Some of advantages of HDPE relative to other hull materials are listed below:
|APPLICATION||Aluminium Boats||HDPE Rhino boats||Fibreglass RIB|
|GENERAL ABUSE RESISTANCE||Poor||Excellent||Poor|
|SANDY BEACH LANDING||Good||Good||Good|
|ROCKY BEACH LANDING||Poor||Excellent||Poor|
Rhino Boats Fabrication
The three main types of HDPE welding are Butt Welding, Tack Welding and Extrusion Welding. In our fabrication process, we mostly used tack and extrusion welding. The tack welding is used predominantly for tacking parts into position which will then be extrusion welded to create the final symbiosis of the boats parts. All welds are prepared with a roughened V-mitre. The HDPE extrusion welding machine comprises of a nozzle that blows hot air to melt the parent material at the V-mitre and simultaneously a worm of molten plastic is extruded into the V-mitre weld prep to create an extremely strong bond.
