Safe. Strong. Fast. Comfortable.

CHALLENGE BUSINESS 45 is a 72ft steel sailing yacht built at the Devonport yards, in 2000.  Part of an extraordinary fleet she was conceived and built to sail around the world against prevailing winds and currents. 

Engineered For Performance

Built under Bureau Veritas supervision to their highest yacht notation, the 12-strong race fleet of Challenge 72-footers was specifically designed to be strong, safe and seaworthy in even the worst conditions.  Designed to be self-sufficient for long periods at sea, with enough fuel and water to take their crews safely to a distant port. The yachts were also designed to be relatively easy to sail and handled by crews who are not professional.

Designed by Rob Humphreys, the identical 72-foot (22 m) steel ocean racing yachts were built by Devonport Yachts in the UK by a new method using a unique flat-pack yacht assembly kit of precision cut laser steel panels.

Legendary Reputation

The Challenge 72' Class yachts have proven themselves to be outstanding yachts; probably the strongest and most seaworthy fleet ever to have raced around the world.

The yachts have an almost legendary reputation for their performance in difficult conditions, comfort at sea and confidence inspiring ability. Their strength and ability also makes them ideal for high latitudes and gives almost unique access to many places that are inaccessible by other means.

New Life

CHALLENGE BUSINESS 45 has an excellent race record and after Chay Blyth’s Challenge Business stopped trading, she was sold together with her sister ships and has a very successful second life as an adventure sailing yacht and was well known as BIG SPIRIT.

However, her career came to an abrupt end in 2011 when she was substantially damaged whilst ashore having a pit stop before a trip across the Atlantic. She fell, lost her rig and sustained substantial damage to her structure.

In her current ownership she is being brought back to life as they are refitting the yacht in collaboration with Mecal the MCA notifying authority who are overseeing the work. Mecal have been involved with the Challenge 72’s from build and they will ensure that once repaired, CHALLENGE BUSINESS 45 will be in condition to code to MCA Category 0 giving her the ability to sail commercially worldwide with charter guests onboard. 

The Challenge 72' class yachts quality equipment and sound engineering ensures reliability and low maintenance costs.  The design lends itself to a wide variety of uses as well as Ocean Racing. The deck layout and accommodation makes the yachts suitable for corporate entertaining, adventure sailing, chartering and private use.
