How to choose the correct clewblock

Rutgerson’s Clewblocks come with a 60 mm, 80 mm or 100 mm removable acetal sheave. In the diagram below you will see which model we recommend depending on boat size. Please note that these are general recommendations, based on standard boats cruising in average weather conditions, and the clewblocks can only be ordered through a Rutgerson distributor or local sailmaker.
