Many thanks again for the excellent advice. We have decided to attempt to splice a split-tail main sheet (or at least my friend is…I have no skill in that regard). My one remaining question relates to the length of the twin tails. They obviously need to be of equivalent length. However, should they be spliced so that the junction between the tails and the mainsheet proper meets at the aft end of the boom when it is centred? Or should the junction between the mainsheet proper and the tails rest at some point along the boom when it is centred? Is there are an ideal length?
Many thanks in advance for any guidance you can give us.
