Basic Set Up
This allows us to populate this form with the correct questions for your particular boat.
How are your jib cars set up?
(Required)
Chances are you have one pair port and starboard, but if not, select that here.
One pair of jib car tracks
Two pairs of jib car tracks
3D Sheeting, no jib car tracks
Do you have athwartship tracks
(Required)
These are the tracks that run from the centreline out, rather than for/aft.
No athwartship tracks
Yes, 1 pair athwartship tracks
From the Hoisted Halyard
This section is all of the measurments you'll take with the tape measure hoisted on the halyard.
Maximum Hoist (Bow) (m)
Connect tape measure to the headsail halyard and hoist to maximum height. Measure to intersection of deck and forestay, measure past furler cans and tack attachments.
Maximum Luff (Bow) m
With tape measure still connected to halyard at max hoist, now measure to the bearing point (BP) of the tack. That might be the shackle pin or curve of hook, whichever part of the sail connects with the sail hardware.
Jib Cars for Hoist Height
It makes sense at this point to move one of your jib cars all the way forward, and the other all the way aft, that way you're not moving them mid-measure, we'll use these reference points throughout the measure, so leave them uneven until we're done. You might never have them this far forward or aft currently, but giving us the full range allows us to keep our options open.
Jib Car 1 - Car Forward Max Hoist
Coming back to the jib car, move the jib car to it's most forward position. Measure the max hoist on the halyard, now down to the bearing point of the jib car as it sits forward. This is most likely the lower surface of the car's sheet roller. Note, even if your current wardrobe doesn't utilise the full range, it's important to measure it so we're not inheriting poor design choices from the past.
Jib Car 1 - Car Aft Max Hoist
Now move the jib car to it's most aft position on the track and measure the max hoist to the jib car bearing point. This is most likely the lower surface of the car's sheet roller.
Jib Car 2 - Car Forward Max Hoist
Coming back to the jib car, move the jib car to it's most forward position. Measure the max hoist on the halyard, now down to the bearing point of the jib car as it sits forward. This is most likely the lower surface of the car's sheet roller.
Jib Car 2 - Car Aft Max Hoist
Now move the jib car to it's most aft position on the track and measure the max hoist to the jib car bearing point. This is most likely the lower surface of the car's sheet roller.
Athwartship Track - Outer Max Hoist
With the halyard still at max hoist, now measure from the bearing point of the roller to the max hoist, this time with the car all the way outboard.
Athwartship Track - Inner Max Hoist
With the halyard still at max hoist, now measure from the bearing point of the roller to the max hoist, with the car all the way inboard.
