An unsinkable airboat with full internal space and utilisation now a reality from September 2007

Fully swamped and heavily loaded on the final test day and yet still afloat and very stable, even with a live ballast on the aft side

How did we do it?

A. The swamp test load was 1100 kilos of calibrated weights.

B. The vessel was fully swamped with 25 mm of water inside the vessel above surrounding sea level and water flowing over the transom.

C. A 100 kilo live weight was posted at all four corners and the angle of list was less than one degree!

D. A further 10% of overload was then applied and the vessel was left in this condition for a full hour

E. Just as the vessel was weighted with calibrated scales prior to the swamp test, it was immediately weighted minutes after retrieval with the same calibrated scales and the difference was zero, thus proving the integrity of the special buoyancy tanks responsible for the unsinkable factor.

The before and after weigh in with calibrated scales proves the design and construction

Where did we do the full swamp test and when?

After substantial design, calculation and further construction the new version was tested to the above tough criteria at Throsby basin on the Hunter river Newcastle NSW on Friday the 14th of September 2007.

It passed with flying colours and we can now build to your order

Adding the calibrated weights to put 1100 kilos of load inside the vessel.

The internal buoyancy tanks aft near, but not intruding on the engine and propeller.

Forward buoyancy tank, all tanks made from checker plate

Floating again with no water inside the vessel but still a 1100 kilo load!

The task at first seemed beyond the realm of the possible, but the photos show it was possible and is now available. Our engineering made several breakthroughs and we can now offer the most advanced non sinkable airboat in the world.
