Jomo boats have undergone rigorous testing to ensure their strength and toughness, buoyancy, and stability and handling. No other boats of this size can meet the standards of a Jomo Boat which has been designed by a naval architect.
Hull Designed by Naval Architect
The Jomo difference starts with the hull being designed by a naval architect. Many principles of hull design used by larger boats have been incorporated into the Jomo hull design. The superior hull design makes getting on the plane easier. During turning, the Jomo hull is responsive and stable. The bow design makes this boat very dry in choppy seas compared to other boats. A long-shank motor is needed because the transom has been designed to prevent backwash from entering the boat. The boat remains dry even going from full power to idle.
Strength and Toughness
Jomo Boats are made of polyethylene which is a very tough and resilient plastic. Jomo boats have successfully passed a 10 metre drop test and a 500kg drop test as seen in the video. The hull integrity was not affected. There were merely some surface scratches from landing on the stones.
Polyethylene (PE) was chosen because of its superior qualities over aluminium, fibreglass, and inflatables. PE won’t crack or delaminate like fibreglass, won’t deflate or tear like inflatables, and won’t be punctured if it hits rocks. PE is also lighter than water giving it inherent positive buoyancy compared to other materials. PE is also more resistant to algae buildup compared to other materials.

The Australian Builders Plate (ABP) Standard requires that relevant new boats sold in Australia are fitted with either basic or level flotation.
Jomo boats have level flotation which is superior to basic flotation.
Basic flotation ensures that a boat is fitted with enough flotation to keep the vessel floating in some form (typically upturned and largely submerged) in the case of swamping, flooding or capsize. In this circumstance, the occupants will be partially submerged in the water, clinging to an upturned hull and risk becoming hypothermic.
As pictured, a vessel with basic flotation can end up largely submerged.
Level flotation ensures that a boat is fitted with adequate and well-located flotation, meaning the vessel should float level with the waterline, providing a safer place of refuge in the case of swamping, flooding or capsize. If the vessel becomes swamped or flooded, it is less likely to capsize due to the location of buoyancy under the gunnels.
Level flotation provides the best chance that occupants will not be submerged in water. It allows easier access to safety equipment and a greater opportunity to attempt self-rescue by bailing water from the boat.
While level flotation does not provide a self-righting capacity, if a boat fitted with level flotation capsizes, the length of the upturned hull should float above the waterline. This provides opportunity for occupants to climb upon the hull. Whether floating upright or upside down, it provides a larger target to be spotted by rescuers and a larger space for refuge than basic flotation.
