Halyard to Cockpit Challenge

I've run into a specific situation in leading my main control lines aft that some of you may be familiar with. My Columbia 29, which is primarily used for coastal cruising, but may see an occasional gulf stream crossing, has its original mast with external halyards and sheaves at the masthead. Therefore the bitter end of the main halyard reaches the deck forward of the mast.

I'd like to run my main halyard aft, so that I can install a reefing system that I can control from the cockpit (I sail primarily with inexperienced crews and I don't relish having to leave the relative safety and control of the cockpit), but I can't think of a good way to route the halyard from forward of the mast to a deck organizer that is placed aft of the mast without additional fairleads, blocks and so on experiencing high loads and increasing friction.

Has anyone in sailnet community tried to get around this problem on their boat? I'd like to avoid repeating others' mistakes.

Thanks
David

Re: Halyard to Cockpit Challenge

It's pretty common for the a halyard to first pass through a block that is attached to the mast step, then to a deck organizer to align it with a clutch back in the cockpit. No undue forces, if aligned and attached correctly. Is that your question?

Re: Halyard to Cockpit Challenge

We have a turning block attached to a collar at the base of the mast which gives the correct angle to the deck organizer then back. Because your halyard is in front of the mast it may take some positioning to get the correct angle from the block back to the deck organizer. Try to avoid a second block of posssible to avoid increased friction

Re: Halyard to Cockpit Challenge

The pic is kinda busy, but it illustrates what Minne is saying:


lead the halyard through a turning block at the mast step, then back through an organizer, back to the clutch farm at the cabintop winch. this is how the halyards and topping lift are run on my boat as well.

Re: Halyard to Cockpit Challenge

Also do use good blocks and deck organizers rather than fairleads... much less friction.

It is not that difficult to convert your halyards to internal either.. avoids a lot of halyard slap in a breeze too. A couple of slots cut, and exit boxes and you're done. It will also free up masthead sheaves for spares.

Re: Halyard to Cockpit Challenge

Bigger blocks can make the angles better and reduce friction (less surface contact).

It can be done. Sounds like you need an organizer to take it to your organizer. Either way you are making essentially two 90 degree turns.
Don't forget that the angle needs to be clean (i.e. teak blocks to raise and flatten the lead).

Re: Halyard to Cockpit Challenge

Thanks for all the replies. I'm afraid my concern has yet to be addressed (chuckles got it though). Maybe I was not clear.

The problem is not simply how to route lines aft from mast-base turning blocks. It is how to get a halyard from a position well forward of the mast to a deck organizer that is aft of the mast. In other words, going from masthead to cockpit the path might be: mast-base block, turning block, then deck organizer and clutch. In the first photo, imagine the block leading to the jib self-tacker with a line leading to a mast base block at the front of the mast.

Because the line has to make at least a ~90 degree turn IN ADDITION TO it's passage through the mast-base block, I am expecting a lot of friction and an extra turning block with high loads parallel to the deck. I'll try to attach a diagram later.

I'm hoping to hear from someone who has seen this set up in action.

Re: Halyard to Cockpit Challenge

A pic or diagram would be very helpful. Are you saying that your main halyard returns down the front of your mast?

I did find a pic of a Columbia 29 and it appears that you'll have to work a bit to get around the companionway hatch, but I admittedly don't follow the puzzle fore of the mast.

Re: Halyard to Cockpit Challenge

Is the 'mast base' block there now? or are still hoisting at the mast? What sort of mast step do you have?

Don't really see anything wrong with coming down the front of the mast to a corner-mounted mast base block that should give you a fair lead to an organizer, most of which are usually a good way outboard of center.

One of the pictures above shows the jib sheet/self tacker with an extra block on the way to the organizer.. can't see how that wouldn't work for you too. As long as you don't skimp on the blocks the friction should be manageable.
