Chay Blyth's Challenge Business built 2 classes of rugged sailing yachts to MCA Category 0, of which the Challenge 72 is the largest. 10 identical sisterships raced around the world against prevailing winds and currents. CHALLENGE BUSINESS 45 is the ex-BIG SPIRIT, and in this role she was a very successful charter yacht in the Mediterranean and Caribbean. After a serious accident in 2011, she was purchased by her current owners who have repaired the major structural damage and she is now available for a new owner to take on and to equip to their requirements. She has the ability to sail at Category 0 again with the correct refit and equipment. She now needs new rig, equipment and fit out to fit her for more serious ocean sailing.
