Approximate length of reef lines

(1/2) > >>

Krumelur:
I'm about to order new reef lines and would like someone to confirm if the lengths I measured look sane. Note: I'm only replacing the long lines going into the cockpit, not the short ones in the boom.

Reef 1:
From point where line is fixed to the boom up into sail: 2m
Down again: 2m
From end of boom to mast: 5m
Down to the deck: 2m
From mast back to cockpit: 5m
Reserve on top: 3m

TOTAL for reef 1: 19 meters

Reef 2:
From point where line is fixed to the boom up into sail: 3.5m
Down again: 3.5m
Rest same as reef 1

TOTAL for reef 2: 22 meters

The system is a Selden, like this one: https://support.seldenmast.com/files/1380900685/595-992-T.pdf

Maybe one of you has changed the lines and can tell me if I'm in the right ballpark.

I recently changed the reefing lines on our B39 to 10mm Dyneema.
For the boom end I bought:
Reef 1 = 24m
Reef 2 = 29m

We have 2 reefs only and reef 2 is very ‘deep’ . I allowed ‘plenty’ and cut off what I didn’t need.

dont forger to arg some meters vor the for and back in the boom. at the shorter first reeve it might be 2,5 to three Meters each way. for the second reeve you have to add to lengs of the boom. so you have to add 5 and 10 meters to you measurement
if you sail is set to top both slides in boom are nearly to front, at first the second reef, the first maybe in the middle. only than you have the possibility to tighten the front reef line,

Thanks.
What do you mean by "deep" and you allowed "plenty" - did you buy much more than needed?

Good point! The length of line inside the boom is roughly equal to 3x the boom length. The updates measurements are therefore as follows:

Reef 1:
From point where line is fixed to the boom up into sail: 2m
Down again: 2m
From end of boom to slider: 3m (max)
Slider back to end of boom: 3m (max)
From end of boom to mast: 5m
Down to the deck: 2m
From mast back to cockpit: 5m
Reserve on top: 3m

TOTAL for reef 1: 25 meters

Reef 2:
From point where line is fixed to the boom up into sail: 3.5m
Down again: 3.5m
From end of boom to slider: 5m (max)
Slider back to end of boom: 5m (max)
From end of boom to mast: 5m
Down to the deck: 2m
From mast back to cockpit: 5m
Reserve on top: 3m

TOTAL for reef 2: 32 meters

These numbers are now close to Lazy Pelican's. That's a good sign!
