There’s been discussion on the IOMICA Forum about simulating radiosailing races in order to study the effects of different heat racing systems. Specifically, it has been suggested that a bigger number of boats should be promoted/relegated from each heat (currently 4, using HMS).

In order for the simulation to be realistic each in-silico skipper’s performance should be varied randomly around some mean performance index. To anchor the simulation in reality, I’ve here taken the results from the last three international events (2003 Vancouver, 2004 Arcos, 2005 Mooloolaba) and calculated the standard deviation of each skippers score during the series.

There’s a clear correlation between standard deviation and final placing indicating that the top skippers perform more consistently than others. I also find it interesting that the datasets from different events are broadly speaking identical.

Update: Along these lines, Lester Gilber has worked on an Event Simulator, with perhaps the aim of figuring out the most optimal heat management system.

Better late than never - some of my own pictures and comments from the event.

The four man strong IOM-Team Finland who competed at the nordics in Denmark and in Saltsjöbaden a couple of weeks ago took the trip over the gulf to sail at the last Swedish ranking event of the year.

I’ve been wondering if it is possible to measure the level of competition in IOM regattas. Here’s one way to possibly do it. I’ve looked at the winning skippers net score and divided that with the number of races. So we can see that to win a world championship you don’t have to win every race - an average score of around 4-7 will do !
The green dots are from various national championship scores I’ve found.
The red squares are nordic events - I see a clear increasing trend !
The blue dot’s is our national Finnish ranking series - we see that there is still room for improvement.

Ofcourse this is not an ideal way of measuring the level of competition. If one single skipper takes command of most of the races the racing behind him/her might still be really fun… but I do think my plot shows something of the truth.

If anyone wants to send in results with the number of races sailed, the number of discards, and the winners points, I’d be happy to add them to this plot when I have time.

Update: Odd-Oivind Kure commented that what this really shows is not the level, but the ‘closeness’ of competition. That’s true, so I’ve changed the title. (although from looking at the graph there definitely seems to be correlation between level and closeness).

25 sailors from the nordic countries (DEN, FIN, NOR, SWE) gathered in Saltsjöbaden, just south of Stockholm, on the weekend of 15-16 October 2005 to sail in the third and final Nordic Cup event in the IOM class.
