Notes for Skippers taking part in the 2017 Round the Island Race organised by the Island Sailing Club
For a number of years the class association has been approached by members about working with the Island Sailing Club so that entries in the world-famous Round the Island Race can get a class result AND an overall result under the ISC handicap system (ISCRS).For 2017 we have agreed with ISC to trial the removal of the “tick-box” Contessa 32 one-design entry option and instead the skippers should enter in the ISC class. Once results have been calculated for the overall ISC position the organisers will pick out the Contessa 32’s entered under ISCRS and give a class result.
This requires the skipper to provide boat and sail measurement data for their Contessa and while the form is simple the class association is keen to assist in this, if only to ensure that we have as many boats as possible racing with the same standard handicap.
The info below is based on the Class rules and is typical of a “Racing” Contessa from the one-design fleet.
Note that because the class allows the use of Genoa furling systems, and the tack position has to be a minimum distance above the sheerline to make it an even-field for those that choose not to, therefore I have selected “Yes” to the Furling system question.
Note also that Contessa 32’s entering in the IRC class will not get a class result.
I hope the below is helpful and wish you well for the race. I suspect that with the quality of the sailors at the top-end of our fleet we could see some very impressive overall results.
As always, if you have any questions you are welcome to contact me via the Co32 website.
