How do I find the serial number of my Seldén System 30 Performance?

The serial number is usually embossed or printed on the lower fitting of the furling system or on a sticker on the forestay extrusion. On older systems, it may be illegible due to weathering – in this case, a photo can often help, which you can request directly from us.

Are parts of the System 30 Performance interchangeable with the standard Seldén System 30?

Not necessarily. The Performance and Standard versions of System 30 differ in individual assemblies, especially bearings and swivels. Always use the exact system designation and serial number to avoid incorrect orders.

Which lubricant is suitable for the bearings of the System 30 Performance?

Seldén recommends a silicone-based lubricant or special yacht bearing grease for plastic bearings and slides – not WD-40 or mineral oil-based products, as these can attack plastic parts and make them brittle in the long term.

Can I upgrade the System 30 Performance for a larger headsail by installing stronger parts?

The system is designed for a specific load range, which is defined by the entire system – not just individual parts. Upgrading individual components is not sufficient to safely absorb higher loads. If in doubt, ask Seldén or a rigging specialist if the system is suitable for your headsail.
