It also may have been a little more sportsman like to have put off the race until other contestants could join? If not enjoy the champagne!
On the other hand, if two yachts can't be bothered to start then it would be unsportsmanlike of them to complain that one boat got its act together. If you start saying "we don't feel like sailing today so you are a bad sport if you do" then where does it stop? Should the sole starter not have gone out if the other crews didn't start because it was raining and they were wimpy? What about if the other crews don't go out because they have boats that are only good in light winds and the sole starter has been getting beaten in the light winds and hoping for a good blow to Even things up? What about the fact that the crew of the lone starter may have missed a day's work/social occasion/nice cruise/gone out on a cold day etc earlier in the series and now the other crews may be skipping the event for a similar reason?
If the fact that someone wants to go to Aunt Ethel's wedding on a race day means that no one else should start then no series will ever be completed.
As Ramona says, the SIs should state the number of starters required to make a race. The ancient rule was that one starter made a race valid but that it could be over-ridden by the SIs. I can't find any such provision in the current rules either.
