Which genoa track and cars are typically fitted on an Albin Delta 31?
I want to replace the genoa cars on my Albin Delta 31 but cannot find a maker's name on the existing fittings. What track and cars were normally fitted, and how do I identify compatible replacements without changing the tracks?
Answer
No single factory specification for the genoa track and cars is documented well enough to identify the original fittings on every Albin Delta 31. Before ordering cars, check the fitted track's cross-section, dimensions and maker's marks; neither boat length nor a matching nominal track width proves compatibility.
Check the existing fittings
Look underneath and along the sides of the genoa cars, then check the track ends and end stops. A cast name, stamped number or surviving label may be hidden when the car is in its working position.
On a boat of this age, the tracks and cars may have been replaced separately. A brand on the block does not necessarily identify the track. Record the boat's build year, but base identification on the equipment fitted.
Distinguish between conventional T-section track with a pin-stop car and proprietary track carrying a sliding or ball-bearing car. A spring-loaded plunger engaging regularly spaced holes indicates a pin-stop arrangement; adjustment lines and end-control blocks indicate a line-controlled installation.
Unload the genoa sheet completely before removing an end stop or car, and retain any loose bearing balls during removal.
Measure the track profile
Use vernier callipers where possible. A photograph with a ruler alongside helps with an initial enquiry, but small differences in the track shoulders and underside clearance can prevent a seemingly suitable car from fitting.
- Overall top width: measure across the track's upper running surface.
- Overall height: measure from the mounting base to the top.
- Head thickness and neck width: these determine whether the car can wrap around the track correctly.
- Stop holes: record their diameter and centre-to-centre spacing.
- Mounting holes: record their spacing if you may need to replace the track.
Photograph an exposed track end square-on, then take a side view of the car and a close-up of its locking pin. Nominal sizes such as 25 mm or 32 mm help identify older T-track, but they are not a universal standard for interchangeability. Do not assume another manufacturer's car will fit because its advertised width matches.
Seldén System 30 options
Seldén System 30 is a replacement system to investigate for a yacht of this size, but its catalogue does not establish that it was original equipment on the Delta 31. Selection still depends on sail area, sheet loads, the sheeting arrangement and the deck installation.
