where an asymmetrical spinnaker’s clew passes between its tack and the headstay or forestay during a jibe. Compare to: outside jibe. The deciding factor between doing an inside versus outside jibe may be the a-sail’s size. On large boats, such as SC70s or TP52s, with extremely large a-sails, there may not be enough room to complete an inside jibe. An outside jibe is the only option.
