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
Waterline Measurements
Depending on your boat, there can be a great variation in deck contour, luckily the water tends to be flat. We'll take some measurements at key points to anchor them to the plane.
Waterline to Forestay Pin
Tape measure on the water surface, up to forestay pin.
Jib Car 1 Forward Bearing Point to Waterline
It might help to use a batten or broomstick to take the horizontal height out to the edge of the boat. This is the height from waterline to the bearing point of the jib car, when it's positioned most forward.
Shroud Base Height Above Waterline
Jib Car 1 Aft Bearing Point to Waterline
It might help to use a batten or broomstick to take the horizontal height out to the edge of the boat. This is the height from waterline to the bearing point of the jib car, when it's positioned most aft.
Jib Car 2 Forward Bearing Point to Waterline
It might help to use a batten or broomstick to take the horizontal height out to the edge of the boat. This is the height from waterline to the bearing point of the jib car, when it's positioned most forward.
Jib Car 2 Aft Bearing Point to Waterline
It might help to use a batten or broomstick to take the horizontal height out to the edge of the boat. This is the height from waterline to the bearing point of the jib car, when it's positioned most aft.
Athwartship Track Outer Bearing Point to Waterline
Now with the car as far outboard as possible, measure the bearing point to the waterline height.
