Well the answer is in fact that is it both (but not at the same time!). It is the latest vehicle developed by Gibbs Amphibians and is both a water and road legal vehicle.

Over the last few days Gibbs have been trialing the vehicle known as the ‘Humdinga’ along the river Thames in London.

They have also made a number of runs down the river to North Woolwich to use the recently repaired Port of London Authority slipway at Bargehouse Road to show off the versatility of the vehicle.

As you can imagine it causes some interesting reactions when a boat drives out of the river and then heads off down the road!

It is also interesting that it is no slouch on the water with impressive acceleration and speed!

It must have caused more than a few double-take moments for other river users too.

The team were out on the Thames again the next day doing another high speed run up to North Woolwich.

Then in the afternoon the action moved to the Royal Docks (sadly, again, no information from RoDMA about these events in the Docks – yet another missed PR opportunity!) with Gibbs bringing four of their vehicles out to play.

These were the Humdinga which is a amphibious utility vehicle:

The Aquada which is an amphibious sports car:

The Terraquad which is an amphibious Utility Terrain Vehicle (UTV):

The final vehcile was the Quadski XL which is a quad bike combined with a jetski:

There are a number of other vehicles in their range which can be seen here.
