That time they rebuilt a Dutch guided missile frigate into a luxury superyacht

In the late 1970s, the Dutch navy designed and laid down 10 ships of the Kortenaer class guided missile frigates. These were 3900 ton ships with 2x 76mm Oto Melara guns, 2x 2 Mk46 torpedo launchers and 16 missile launch tubes. One of these ships, the HNLMS Piet Hein, was sold to the United Arab Emirates in 1998. There she served until being decommissioned in 2005.

After her decomissioning, ADM Shipyards, based in Abu Dhabi, got their hands on the aging warhorse and set about rebuilding her. The result is the superyacht Yas, one of the largest and most luxurious motoryachts in the world:

I'm not sure what they kept other than the basic hull. Though the Wikipedia entry for Yas lists the same engine power, layout and performance as the Kortenaer class, so I suspect they kept the engines and drive train too.

I honestly think Yas is ugly with that large front window shaped the way it is, but one can't argue with taste I suppose. I'm sure she's a bastion of sumptuous luxury.

Why not just buy a brand new modern superyacht though? :cap_yes:

Why would you, when a perfectly servicable hull and drive train are available?

Well and the windows obviously conceal all the missiles and guns that are there to protect the investment in this luxury vessel.

Well I guess beauty is in the eye of the beholder. I think she's certainly distinctive/unique and pretty damn sleek. The wikipedia didn't have a lot of information but it did have a couple of reference links (one of which had one interior shot). I'd have expected someone would have wanted to show off the interior (oh well).  I bet that front windowed area is pretty fantastic to be in.

I'd think a 30 to 40 year old hull would have some corrosion issues and the machinery would be inefficient by comparison to more modern equipment, not to mention a parts nightmare.  But, the shipyard that converted her probably had people with more money than common sense in mind as buyers...

Remodeling the interior spaces, overhauling the mechanics and fabricating a superstructure is probably a whole hell of a lot cheaper than building a whole new ship from scratch. I'm sure by modifying an existing ship they probably saved half the cost.

I wouldn't be so sure.  First, warships are built to be tougher than commercial vessels.  They generally have more compartmentation,  and machinery for damage control on a level that a commercial ship wouldn't have.  This class is COGOG.  That is, they use gas turbines for propulsion.  One pair is low speed (20 knots), the other pair is high speed (30 knots).

The compartmentation would be tighter.  There'd be magazines and other spaces in the hull that were no longer required.  Then you get into the plumbing and wiring of the frigate versus the much lower requirements for the yacht.  It does look like they took out the high speed gas turbines leaving only the low speed pair for 26 knots (on reduced tonnage) with a 20 knot cruise per the original frigate design.

The hull would still be going on 40 years old.  That means there will be some corrosion and stress issues with it regardless.  The only way I can see them saving cash on this is they got the frigate for next to nothing as it would otherwise be sold for scrap.

For the sake of comparison the Topaz, the 8th largest yacht in the world (Yas is the 7th), was built for 527 million. The Yas was completed for 180 million. A ship built from scratch to fit the requirements would most likely be around 580 million based on the building costs of other super yachts. With 400 million dollars saved, I would imagine they would have the wiggle room to fix whatever issues the hull might have and still come out cheaper than one built new. The owner is a baller on a budget.

The reinforced hull that Warships would have as well as the improved engines are perks a Billionaire could want as well as the size of the ship. Not to mention some Yachts are armed since you can’t exactly call the police if pirates try to attack. And that hull is probably able to to take some hits from weapons pirates would likely use. I know of another yacht they added some armor to certain sections of it to safeguard the VIPs onboard in emergencies, so having a hull that is probably already strengthened would save time and effort.

That huge window is likely to provide a beautiful unobstructed veiw from the inside of sunrises and sunsets.

John Wayne had a yacht that was a converted mine sweeper, though I am not sure of what the tonnage was she had been, at one time, a commissioned U S Navy warship; why shouldn't someone else turn a Missile frigate into their private yacht? Ya gotta know she's seaworthy.

Well, the inside is pretty impressive.

An unusual yet keen idea. 

I may not like the look of the ship as a yacht, but I wouldn't be surprised that some would like to have this former warship turned pleasure boat as their personal toy.

 

I for one, would love to have a small WW1 liner turned merchant raider as my personal yacht.

@Lert Any idea if the Super Yacht Yas is still armed with missiles or not?

Heard at least one Russian Yacht I think it was that was armed with defensive missiles and came with some armor plating as well.. Bet US Home Land Security was nevervous when that particular Russian yacht spent few days sitting in New York harbor while its owner visited US lol. But if you are one of the super rich with massive yacht it makes sense to have some forms of protection against pirates.

I have no idea if Yas still has weapons. Makes sense that she would have something.
