AC Race Management Regatta Director Iain Murray is running two weeks of practice racing in Bermuda, with teams sailing their AC45X test boats. This is the third time ACRM has run training races in Bermuda. All teams were invited, but neither Groupama Team France nor Emirates Team New Zealand is participating. Not only have the French and the Kiwis not yet arrived in Bermuda, they no longer have test boats – they’ve been disassembled for parts for those teams’ AC Class race yachts.

Our contacts in Bermuda say that Artemis and Team Japan seem to be going especially well, but not to read too much into that.

The umpire is making calls on the water, so there is plenty of shouting, especially in the pre-starts. The LiveLine system requires helicopters and a complete technical team to operate it – a bit impractical for practice races.

This is not just for the sailors – it’s a rehearsal for the shore crews as well. There is some flexibility in the work schedule on training days, but on race day the boat needs to be at the starting area on time. The designers will also be getting feedback on how their daggerboard designs are performing. Control systems ergonomics and hydraulics will also get thoroughly tested in race conditions.
