SO44i halyard lengths

[pipemma]

OK, I'm having something of a blonde moment here.... It's Friday afternoon, and my brain is hurting! 

I need to replace all 3 halyards on Cloud Nine - they're 9 years old and salted to buggery and having changed most of the rest of the running rigging, the difference is really showing. However, I'm having difficulties calculating the lengths required.

I guess the main needs to be P (15.27m) plus the length of the mast plus the run back to the cockpit plus a couple of metres' wiggle room. Kite & genoa then 2 x length of mast, plus run back to cockpit plus wiggle room?

The info I have is P = 15.27m and air draft = 19.00 m. Can I guess at 17m mast length then? How much would you allow for the run back to the cockpit? (Boat in GR, me in the other GR(aubünden) and I'd like to take them with me next trip in July)

Thanks in advance!

If you have access to a long tape measure. Use it to figure out what you really need.
Air draft, is distance from waterline to to top of mast. Don't worry about that number unless going under bridges.
I measure from deck to top of mast, then top of mast to top of boom, pulse distance from mast to winch plus wraps, and a meter or so tail. You ma also want to.know distance from top of mast to back of boom, if you keep the shackle when not in use here.
Now you truly know how long you need the line to be.
But, yes, two times I, plus distance to winch plus wiggle will get you close.
Having been in construction for 30+ years, one does not always cut things per plan or a swag.

Pipemma,

This won’t answer your question but may help the budget. As an example: www.marinescene.co.uk/product/11596/52mtrs-liros-12mm-end-of-reel-offcut-braid-on-braid-yacht-rope-blue-flecks

Marty, only problem with that is that unless I defer until next year, or September, I'm not going to be at the boat to measure.

Ian, I often get Liros offcuts at Düsseldorf, really good value. But otherwise, I get trade rates here on FSE Robline, so budget is slightly less of a concern than otherwise. But still a concern for 3 x halyards

[MartyB]

Using a sail plan for a std 44i. 15,27 + 16.54 + 5.3 = approx 38M of line. with the numbers being added equal to main luff plus mast height, plus boom length and about .5 M for wiggle = 38 Meters in length. You may want 39 M if you can not measure the total on site.

My way of measuring is the same as you were guessing and saying using a sail plan.

the lengths you need will be written up in the owners manual.

[alenka]

Agree with Hoppy.

Halyard and sheet lengths/diameters are in the owners manual.

[pipemma]

Hoppy & Alenka, you'd think, wouldn't you? But my owner's manual seems to be pretty shite and never contains the information I'm after. Same problem, though, with not being at the boat at the mo...

[alenka]

Try downloading the manual from this site.

I did it for the 43DS and it has the halyard and sheet lengths.

Good Luck

Good news! The 44i manual is there now.

Bad news! It's just as rubbish as I remember. Nothing about sheets & halyards in there

[aljoul]

Pic1 SO44i ,pic2 SO45 , pic3 SO45 maybe give an idea.

[pipemma]

I wish. My equivalent of your p 55 with the running rigging has only the hardware

I have to put a shout out here for Ian Scott at Clarke and Carter. I bought original decals from them last year so I thought I'd be a bit cheeky and ask if he knew the answer re these halyards. No money in it for them, but he's been really helpful - he sent me a screenshot of the Jeanneau spares site with the manufacturer recommendations, which I would post here if I could work out how to post pics now photobucket is useless.

Anyway he wrote:

I believe the halyards are as follows:

Main: 43m x 12mm

Boom topping lift: 36m x 10mm

Genoa: 40m x 14mm

Spinnaker halyard: not listed separately but guestimate at least 45m x 12mm

Now these actually don't make sense to me - I don't see how the mainsheet should be longer than the genoa, or the spi even longer still. However I'm going to average them out and get 43 m for each of them. My supplier has made me a good offer on 12 mm dyneema core, so that's what I'll be going for, in case it's of interest to anyone in future

[pipemma]

Update: I got 43m each for the main & spinnaker and 40m for the genoa (because my supplier had an excellent deal on 40m in the right colour with an excellent captive shackle). The main is probably 3-5m longer than it needs to be but it’s not a problem; the others are bang on

Hi
I am having my own blonde moment as I thought I had found a version of the manual with all the halyard lengths in it, maybe the printed version but i am away from the boat and need to order the new ones before I return.  Can I confirm the lengths you are quoting are for So44i standard version, stack pack sails.  

Do you happen to have a length for the mainsheet as well?

What type of lines did you use, Dynema is very costly, do you think a line like New England ropes sta set x would be good enough for the main halyard?

Thanks

[MartyB]

Andrew,

I would NOT use sta set for a halyard on a 44i, much less my 30' Arcadia. You can be a size or two smaller with a dynema than you need with sta-set. Also, dynema is stronger many times by 2, with 1/4 the stretch. Dynema lines are typically .6-1% stretch at 30% of breaking strength, sta-set in the 3-4% relm. For a halyard run that is 50' from top of sail, down the mast to where you cleat at back top of cabin, a dynema line stretchs maybe 6", vs a staset at 1.5-2'! BUY the dynema line!

I would also suggest it for sheets too!

PS,
I see I was off a whopping meter or 3' for the mainsail halyard on OP's boat, based on E + I + boom length and a bit more for measure! Not bad, I was this close on my boat too!
