ARKO III : The all-time best showjumper !
Amazing with Nick Skelton, this wonderful stallion
, such handsome and clever,
is the best son of Argentinus.
Even though he began lately his real stallion career when he stopped competiting, Arko already produced some international winners like Argento and is regularly placed among the best sires of young showjumpers.




ARGENTINUS, his sire :

He was acknowledged to be the best son of his sire Argentan I and sired over 400 showjumping horses in Germany alone as well as 27 graded stallions worldwide.

He was Champion Oldenburg and Hannoverian Stallion of the year.

He was until recently when he passed away the most successful stallion in Germany with progeny winnings of 3.5 million Euro's !


Argentinus' offspring distinguishes itself in breeding shows, jumping and dressage competitions. He counts more than 30 approved stallions and many awarded mares. Among his most wellknowned progeny, we'll remember besides Arko III the horse of Nick Skelton's come back (2004 OG) : Aramis, born in 1984, the first one who arrived at the highest level ; Autogramm, born in 1985, great Grand Prix and Nations Cups winner ; Anka, winner of the 2003 Worl Cup with M. Ehning ; Albano, team gold medal at the 2001 European Championships with H.Kemmer, 3rd of the 2003 dressage World Cup ; Grace Argentina, internationale winner with L. Beerbaum ; Air Jordan, CSI (winner of 1,5 million Euros) ; and also Armitage, Azzaro, Anastasia III, Asti Spumanti, Adlantus As, Atlantys by Wisbecq, etc.

UNIKA, his 1st dam :
Directly used as a broodmare, she has also produced :
Amati P.M.S., Arko's full sister, winner of 1,45m classes (S**-Springen) and dam of the SF stallion Tsunami de Hus ISO 154,
Arka and Quinta P.M.S., two other sisters, winners of 1,35m classes and
Arko ESI, Arko's full brother, who achieved the highest price for a foal sold through a German auction 130,000 Euros !

Unika's sire, the Dutch-bred Oldenburg stallion Beach Boy (Nurzeus / Lucky Boy xx), has been incorporated into the breeding programme of the Swedish State Stud at Flyinge. He has sired 8 graded sons who are already making a name for themselves and his own progeny includes the 1991 Oldenburg performance test champion Brandenburger, the international showjumper Beach Game and the international eventers Beach Star and Feldschwalbe.

UNIQUE, his 2nd dam :
She has a 3/4 french bloodline here we find back the famous thoroughbreds Le Mioche xx and Monceaux xx.
Directly used as a broodmare, she has also produced :
, World Cup Eventing with Peter Thomson
and two other horses : Masur 53 and Classic 15 who won 1,35 m classes.

The real power behind the success of Arko III is established in the lineage of the mother, namely mare lineage 002. This wide spread family is the base of a long list of international show jumpers : Now or Never (Piet Raymakers), Alanda (Pieter Kersten), Opium (Marcus Ehning), It’s the Business (Goeff Glazzard), Friso (Guido Dominici) and the legendary Darco, who took a 6th place at the World Championship in Stockholm (1990), a 7th place at the Olympic Games in Barcelona (1992) and produced several CSI winners, ranked now World Best Stallion of showjumpers.



Arko III will remain in all memories as an extraordinary showjumper. Under the saddle of Nick Skelton, he stayed for 7 years at the Top International level, always present at the major shows, World Cups, European Championships and Olympic Games (10th at Athens in 2004).

"Arko is
says Nick Skelton.
"He was the only reason of my coming back to competition in 2001 after my accident. I thought that this young horse was a crack and he became one ! He had everyhting we dream for a top sport horse.
He was amazing !"

"With Arko, it was more flowing than with Big Star, reminds Philippe Guerdat. I loved this horse. Together, they were closed to perfection."
