THIS amazing £1million boat can flip itself back over if it capsizes.
Dubbed the "Thunder Child" the stealth yacht even comes with remote control machine guns.
The party trick is its watertight design which means it will self-right if it finds itself the wrong way up.
The amazing clip shows how it gets back on its hull completely unaided.
The remote control machine guns can be deployed above decks through hatches and are fitted with an independent gyroscope so you can fire straight even if you're tearing through giant waves.
They can be hidden out of sight when you're cruising around.
And the boat, produced by Safehaven Marine, can hide from radar thanks to its sleek design.
Fitted with twin 1,000bhp engines, the patrol craft can hit speeds of 64mph.
Long range fuel tanks on the XSV 17 model mean you can travel 806 miles before needing to head to the pumps.
The inside can seat 10 with special seats to take the bumps of huge waves.
And there's even a sleeping compartment for overnight patrols.
The cockpit is kitted with the latest GPS systems, HD radar, CCTV and night vision.

It measures in at 17-metres and weighs 19,500kg when it's fully loaded.
It's been designed for naval, law enforcement and offshore patrol use - plus as an emergency response vehicle in dangerous waters.
A version of the boat was recently put on sale for €1.2m (£1m) in Ireland.
