Product Features:

This series 60 plain bearing inhauler block is used on racing yachts with longitudinal genoa track systems. The purpose of this block is to deflect the genoa sheet inboard over the coach roof to allow a narrower sheeting angle. The genoa sheet passes through the series 60 plain bearing sheave, and a 2:1 inhauling purchase is created with the series 50 plain bearing sheave. An extra purchase system is normally used to inhaul this block providing a total inhauler purchase of 8:1 minimum. Typical situations when this system is put to good effect is when racing on flat water the yacht may easily achieve its target speed to windward, the inhauler is then applied to slow the boat back down to target speed and hence gain extra height to windward.
