These were Aurora, a P&O owned ship (same parent company of U.S.'s Princess Cruises), which is geared to a British market; Europa, a small, 80-passenger ship owned by Hapag-Lloyd and also primarily marketed to a European cruiser, and Le Levant, which sails America's Great Lakes.
Near-misses in the CDC's perfection derby include Disney Wonder and Clipper Adventurer. Both scored an also-impressive 99.
Sadly, there was no opportunity to re-exam Cape May Light, which last month failed its CDC exam with a 79 score, before its parent company, American Classic Voyages, halted operations and filed for bankruptcy. That means the new ship, just launched this year, will remain on the dubious "failure" list until if, and when, it ever resumes sailing.
