Our kit includes six pieces to make it work smoothly on your Catalina with 1" t-track installed:

• (2) End control blocks, with double cheek blocks and becket, placed forward of the cars
• (2) Low lead genoa cars with double blocks forward and bail aft
• (2) Swivel leads with cams on cars to mount aft for additional control

See "May we also suggest" below for the appropriate control line set.

• For T-Track with 1" maximum track width
• Length of forward car: 4-1/2"
• Length of primary car: 6"
• Length of aft car: 3"
• Diameter of genoa car sheave: 3"
• For maximum diameter line: 1/2"

1) One half of the kit is shown. The track pictured is for reference only and is not included with the purchase. You will be installing three cars on each side of the boat, on your original genoa tracks.

2) 5/16" line is a good balance between easy to grip and low friction of the line passing through the blocks. Different boat models and vintages use different length track, so you will need to measure to determine the length of line necessary for your boat. Be sure to leave extra length for the tail to reach the cockpit if desired.

See "May we also suggest" below for the appropriate control lines sold by the foot.

3) Some models in some years have the genoa track mounted flush in a groove in the deck. In these cases there is typically only ~4" of empty recess forward of the track for loading the car onto the track. If this is the case, you will want to remove the entire genoa track to install the longer 6" primary car. In theory you could remove only the forward three or four bolts and flex the track up a bit to slide the car onto the track. The problem is it would be difficult to properly re-seal the aft-most bolt that you removed. In reality, all deck hardware should be re-bedded every 10 years, so it is probably time to re-bed the entire track anyway.

On boats with flush mounted tracks mounting bolts are secured inside the boat using nearly flush barrel nuts. If there is one fastener that happens to fall at or near a bulkhead, making it impossible to use a nut inside, Catalina laminated a metal plate into the deck. That one fastener was installed into a drilled and tapped hole in the plate. There is no visible nut inside the boat in that location.
