We use only our Krypton Dyneema core, Dacron cover line for halyards. This 3/8" line has a 11500# tensile strength and extremely low stretch. Its low stretch provides excellent control of sail shape over a wide range of wind conditions.

Although many customers ask about splicing the halyards on a Catalina 30, it is not recommended. Remember that the masthead was designed for wire halyards. Therefore it is narrow where the halyard passes over sheaves and through the masthead. Although it is large enough to accommodate the line, it is not large enough to accommodate the splice. Both the length and diameter of the splice will mean that the splice will jam into the masthead, chafe , and fail prematurely.

We recommend re-using your old halyard shackle and securing it to the halyard with a bowline , just as the factory did. If you need new shackles, see the related items below.

The length of this item is based on the original factory specifications. However, the previous owner, like Captain Jack Sparrow, may have had an entirely different idea about how to rig a boat! Please confirm this is the correct length for your particular boat. We cut it from a long length and can't splice it back together again. Your order cannot be canceled, returned or exchanged, but, like Jack, you may have a different idea of what you can use it for!
