This 13-tonne military vehicle has all-round protection against artillery shell splinters and can stand extreme temperatures of minus 50 - but at the weekend it developed a leak and sank at Fox's Boatyard in March.
The OT64, an amphibious vehicle made in Czechoslovakia and Poland in the 1960s, was being given a test run by its owner, businessman Richard Moore, but after sinking is still in the marina awaiting a winch to pull it out.
Mr Moore, who operates a specialist firm in the town trading from Eastern and Central Europe and exporting to other Western European countries, said: 'It's not the end of the world.
'I'll just get it winched out, drain it and give it a good clean up. About two days work I should think.
'Luckily it is not damaged in any way. I killed the engine and bailed out.'
The 8x8 troop carrier is just one of a collection of vehicles that passes through Mr Moore's ownership as part of his business, Russian Military, which the website says is the country's leading importer of Russian and Eastern European military trucks, tanks, jeeps, planes, boats and related parts.
Many of his vehicles are exported to collectors worldwide with staff handling the necessary documentation.
'There was a very competitive cold war during the seventies, therefore the Kremlin had to pump funds into the military to enable them to build solid, reliable trucks and tanks and APCs to a very high spec,' the website says.
'The end results were very reliable units that could stand for months, operate in -50 to +50 degree temperatures, and at the same time be very easy to maintain.'
