Sadly this is far from being a new problem.
“The standard of rule observance below the top third of the fleet is poor to appalling and, surprisingly, only one protest arose out of the meeting which was for a minor infringement compared to some of the mayhem that arose at the turning marks. This is a feature of the event which BIFFA needs to take on board for the good of the class. If ‘on the water umpiring’ had been used they would have been extremely busy, while of conventional protests had been properly applied the protest committee would still have been sitting on Tuesday!”
That is the final paragraph of the report on the 1992 Inlands.
Until class members start to protest, or we start to use on the water umpires (with an interest beyond rule 42), this won’t change. The use of umpires will almost certainly drive up the cost of the events, which may reduce the turnout. Protesting also relies on the the host club being able to find a protest committee that properly understand the rules, which has also been a problem in the past, otherwise the outcome can be a lottery.
