Which genoa track and cars are typically fitted on a Hallberg-Rassy 342?
I'm trying to identify the genoa tracks and cars on my Hallberg-Rassy 342 before buying replacement cars. Are these a standard fitting across the model, and what measurements should I take to make sure replacements fit?
Answer
A Hallberg-Rassy 342 with the standard genoa typically has side-deck tracks with adjustable sheet-lead cars, but check the fittings aboard before ordering replacements. The available factory specification names the rig, furler and winches but gives no genoa-track manufacturer or car series, so the boat model alone cannot identify the brand and size.
The original genoa arrangement
The HR 342 specification lists a Seldén fractional rig, a Furlex 200S roller-furling system and an Elvström genoa. This identifies the standard headsail arrangement, but does not tell you whether a particular boat has Lewmar, Rutgerson or another make of genoa lead.
A Seldén mast or Lewmar winch does not identify the deck track. Manufacturers supply different parts of the same boat, and previous owners may have replaced the cars or complete tracks.
Some HR 342s also have a self-tacking jib installation. Its transverse track and traveller form a separate system from the side-deck genoa leads. Identify which equipment you are replacing before comparing catalogues.
Identify the maker and profile
Start with markings on the car body and the rail's end profile. These tell you more than the boat's age or the sheave's appearance. A replacement sheave or block may carry a different name from the original car beneath it.
- Clean the car and look for a maker's name, logo or part number in the casting or marked by engraving or stamping. Check both sides and any accessible underside.
- Photograph the complete car from above and from the side, including its adjustment mechanism.
- Photograph the exposed end of the track beside a ruler. If an end stop obscures it, first measure the accessible rail without dismantling anything.
- Use vernier callipers to measure the rail's top width, overall height and upper-flange thickness.
- Measure the spacing and diameter of any adjustment holes. Record the fixing-bolt spacing too if you are considering replacing the rail.
A measurement of about 30 or 32 mm is only a starting point. These are different nominal sizes, and rails of similar width can have different shoulders, running surfaces and clearances.
Check movement and locking
The adjustment system helps identify the replacement and any additional parts it needs.
- Pin-stop car: a spring-loaded plunger engages holes in the track. The replacement must match the rail profile and locking-hole arrangement.
- Line-controlled car: a control line moves the car through purchase blocks. Match the car, control blocks, end fittings and line routing as a system.
- Bearing car: rollers or balls support movement. Identify the series before sliding the car off the track; some designs need a loading rail to retain loose bearings.
