We need a new main halyard for our 22 year old 45’ Hunter Passage 450. Not racing, just local/coastal cruising. Trying to figure out what size is best - 11 or 12 mm, 7/16 or 1/2”. And what material. Thanks much. C

I would go for the 10mm, way stronger than what you need, you could probably get away with 8mm, smaller in the hand but lighter on the wallet

If you go with halyards that are smaller than what you currently have, Check to make sure that the rope clutches are compatible smaller diameter line. Clutches are made to hold specific diameter lines.

What @DrJudyB says...:plus:

Of equal consideration, you are talking about a halyard. You will want to be sure that the size is compatible with the size of your mast sheaves. Too big and they jam or provide friction making raising and lowering a sail a problem.

Thanks. I might go with 11 mm or 7/16”. The’re just about the same size. It’s either one of these or 1/2”.

Now that you have the size selected, double braid polyester with a dyneema core would be one choice to consider for your application. Low stretch but still good handling characteristics.

Racing doesn't really matter. You want a halyard that doesn't stretch much. And I mean very little. A halyard is a sail control and if it stretches in gusts or higher winds your sails won't perform as well making your boat more tender and likely to misbehave. I would venture to say that the best money spent on running rigging is on halyards. Runner up might be reefing lines.

And I usually order my halyards with a shackle spliced on one end. That makes a nice clean installation.
