APPROVED MOD: JIB FOREDECK GUIDE BLOCK COVER/BASE

[JohnPorterSailing]

This base is machined or 3D printed and replaces the standard base on the Harken foredeck jib guide block.  Must be made out of black plastic or delrin.  This replacement base prevents the jib sail and spinnaker sheet snags in lieu of the duct tape and mylar covers.  This change to original supplied equipment is approved by the Technical Committee.
