A
jib inhauler is a block and tackle mounted on the cabin top that is mostly used with newer style boats that do not use overlapping
jibs. They are located just about abeam of the clew of the
jib and pull it horizontally inboard. This allows the boat to point a bit higher in flat water.
Most of the boats that most of us sail actually have their windward ability limited by the performance of the keel and the interaction of the mainsail and
jib so an inhaul would not do us much good, But if you sail a very modern design with the current trend in high efficiency foils and non-overlapping
jibs it is a very helpful tool. Occasionally you see the principle of a inhauler used on a boat like a J22 which has a comparatively wide shroud base.
