Luxury submarine manufacturer Migaloo has released images for a 165-metre superyacht that lets owners journey beneath the waves on the ultimate off-grid adventure.

The fully customisable M5 model not only converts into a submarine but also includes a helipad, hangars with room for hot air balloons and trucks, and two extra individual submersibles for guests who want to strike out alone.

According to Migaloo, the yacht can remain submerged for four weeks and has room to accommodate up to 20 guests and 40 crew and staff. Early concept images show the M5 ploughing through the ice before stopping off to explore with a matching Migaloo expedition truck and coasting beneath tropical seas.

Owners can collaborate with the Migaloo team to tweak the design and interiors and install whatever equipment they need. Price is available on application – but is estimated to be around the $2 billion mark.

The submergible superyacht has a range of 8,000 nautical miles with a speed of 20 knots at the surface and 12 knots when submerged.
