Specifications of The Challenge 72 One-design
The current 12-strong race fleet of Challenge 72-footers was developed from the Challenge 67s and was specifically designed to be strong, safe and seaworthy in even the worst conditions and 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.
Ten of the twelve yachts were built by Devonport, UK, the other two by Kim's Yacht Company in China.

“The challenge of screenwriting is to say much in little and then take half of that little out and still preserve an effect of leisure and natural movement.”
