Here’s a question. I too am repositioning the fairlead tracks. I’m just wondering about shortening them too. They are 30cm – seems like the standard length – but it there any reason why they shouldn’t be shorter? With the racing genoa the fairlead block position will never be varied by more than 10cm max. Is it the case that the remaining 20cm is purely for use with reefed or smaller headsails and therefore won’t be needed if one never uses such things or is there a class rule or some other good reason for keeping with the standard length? My crew would love an extra 20cm of comfy light airs lounging room!
