1) Due to the lack of whisker stays supporting the bowsprit laterally, we don't recommend lying at anchor while the rode is reeved through the roller. When the boat sails on her anchor, the roller must support a tremendous load when she comes up short on the anchor on one tack. Always use a bridle that leads from the anchor line to both mooring cleats.
2) Some customers report the teak bowsprit on their early Catalina 30 is too narrow to accept the width of this newer model stem fitting. Please measure carefully before ordering. You may decide it is necessary to replace the teak bowsprit with the later, wider part. (bow sprit)
