I am considering adding the catalina bow sprit to my std rig Catalina 30 so that I can get improved weather helm amd to ba able to add an anchor roller. Does anyone know of a "how to" article? More specifically, How much needs to be added to the forestay to accomplish this? I have a Harken roller furling setup and was wondering if I can just add a fitting to extend the forestay?Thank in advance for your help.
