Okeanos Aggressor I

CocosOkeanosExt1 opt786

Okeanos Aggressor I is a 110' yacht, built and powered for comfort, safety and stability on the crossing to Cocos.  She's been doing the Cocos run since 1988 in that typical Aggressor style.

"My very first trip to Cocos was in 1988 ... on the maiden voyage of Okeanos I to Cocos Island!   She was stable, comfortable and efficient then .... and remains so today.  The always excellent Aggressor standards will be a part of your unforgettable journey on the Okeanos I.  And, the diving, of course, will astonish you."   ...   Dominick Macan
