Dragonfly 40 Maintenance
Exchange intervals of structural parts
Dragonfly 40 Touring, Ultimate, and Performance (built since 2020), and all C-versions (built since 2022)
- Waterstays – every maximum 10 years or 25.000 NM.
- Side stays and forestay cables in Stainless Steel – every maximum 10 years or 20.000 NM.
- Fiber Side stay cables (DF 40C and sometimes ordered optional on other boats) to be replaced after 7 years and or max 20.000 NM.
- Diamond stays on the mast should be changed after 15 years at the latest, or, by max 25.000 NM.
- Beam stop cable to forward, outside beam under trampoline – every maximum 10 years.
- Halyards and Dyneema lines need regularly visual check for wear and tear.
- Steering cables – every maximum 7 years or 15.000 NM. Regular visual control is strongly recommended and especially before planning longer trips.
The above listing of exchange intervals is the recommendations from the Dragonfly yard, and it is not an extension of the 2-year warranty committed from when the boat was new.
From January 2024 we engrave the Dragonfly logo including a production year, on all rigging terminals on structural wiring such as waterstays, side stays and diamond cables, to make it easier for you as a customer to follow the above recommended exchange intervals.
IMPORTANT: Always check very carefully that you replace cables in the same type of cable quality if not ordered/replaced by the Dragonfly Yard.
Rigging
Visual check of all cables is still required before and when changing the rigging. We strongly recommend focusing on side stay cables, as these easily bend when stepping the mast. Bended side stay cables near the terminal may cause the side stay cable to break.
On all Dragonfly’s, please regularly check the forestay cable in the top by the terminal. When furling, the spinnaker or Code-0 halyard may block the forestay, which can cause failure of the forestay.
Trampolines
On all Dragonfly’s, we recommend re-stitching (sewing) along the stitching/seams of the trampolines every 6-7 years (in climates with strong UV, every 5 years). Normally, our clients change their trampolines after 10-12 years use. Please note this is an recommendation and it is still always the skippers responsibility to regularly check the condition of the trampolines.
Float deck Teflon pad rings
The white 5 mm Teflon pad rings on the float deck needs to be changed every 13-15 years – this is neither critical nor structural. For easy change of these pads/rings, you just bolt off the floats from the wings by the one bolt in each end of the Wing/beam.
Quick-links
Over the years, Quorning Boats has used the riggings links, so-called Quick-Links, in the Dragonfly production quite often. When replacing these, it is of utmost importance to purchase links of same high quality or similar products carrying same strength (working load). Many products look the same, but do NOT carry the same strength/loads. If you are not sure about this, please contact your local dealer or the Dragonfly Yard.

Painting
Caution for all painted surfaces on the boat and mast
Painted surfaces may not be covered with Plastic or other non-breathable materials, as water and condensation cannot be lead away from the painted surfaces, and these are not able to dry.
When water is stuck between the Paint and a non-breathable or non-ventilated material, blisters can occur between the paint and the gelcoat or the carbon sections of the mast.
Due to these circumstances, the permanent use of Ex. Matt-Fenders cannot be recommended, as water and Condensation can also get stuck between these and the hull, and lead to blisters in the Paint.
Quorning Boats cannot be held responsible for Blisters in the paint occurred due covering the painted surfaces with non-breathable materials.
Ordering parts
Original parts can be ordered at Quorning Boats at aftersales@dragonfly.dk
Common spare parts can be shipped within two weeks, whereas special parts and/or custom-made parts usually are served within 6-8 weeks.
Important
Parts ordered at Quorning Boats Denmark, will be produced in originally designed materials. Should you choose to order from other suppliers, please check that the same kind of materials are used – especially on the waterstays and other rigging parts, where stronger Dyeform cables are needed.
