If you weren't aware of it the UK MOD has 3 yachts competing in the annual Sydney-Hobart yacht race: Adventure of Hornet crewed by the RN; Discoverer of Hornet crewed by the RAF and Challenger of Hornet crewed by the Army. All the boats are Challenge 67's.
Currently, the RAF boat is leading the three (although well behind the race leaders) with the Army bringing up the rear by a long way.
