IOM appendage design questionnaire

IOM hull and appendage design has changed little since the introduction of the iconic Britpop! in 2010.
But is seems the latest designs are slowly morphing, moving the rig and fin further aft with a fuller hull forward.
One unintended consequence of this is the CG of the bulb is also moved aft, unless the bulb is moved forward on the fin.

I’ve created this informal survey to collect measurements from all designs of IOMs in an effort to confirm or refute this assertion.
Please take a few minutes to grab a tape measure and complete this survey.
The results will be displayed once you submit your data.

Thanks, Art
