Track Entry

D - Mast Track Gate Entry Height from boom (in cm)

Measure the height from the top surface of the boom/gooseneck to the top (highest) opening of the mast gate. This allows us to tailor the sail tack nicely. Again, if you have a boom top surface that drops away, project the top surface of the boom across to the back surface of the mast and measure this distance.

How does your main foot attach to your boom?*

Loose (Along Foot)

Bolt Rope

Am Measuring the Track Internals

Base Width of Slide or car

(Leave blank if you have a bolt rope with no slugs) This is the widest part of the car or slug as it sits in the mast track. If it's a round slug, then it will be the diameter of the slug. If it's a flat based slug, then it will be the maximum width of the base.

Slug / Slide Neck

This is the width of the neck of the slide as it comes out of the mast. (Leave blank if you have a bolt rope with no slugs)

Luff Rope Diameter (mm) (if using luff rope)

Please also note if you used a drill bit to size the track, or calipers to measure the luff rope.
