Dragonfly 1000 Maintenance

Exchange intervals of structural parts

DRAGONFLY 1000 (built 1991-2002)

• Waterstays – every 5 years, or by max 10,000 NM
• Side stays and forestay – every 7 years, or by max 10,000 NM
• Diamond spreader stays on the mast – every 15 years
• Steering cables – every 5 years

Once a year, please check and tighten all bolts/nuts on the wing/beam stainless fittings.

We recommend changing the original stainless 16 mmm wing/beam pivot bolt to one of 18 mm (made of high-grade stainless steel). Later models have a standard 20 mm pivot bolt.

Dragonfly 1000 up to hull No 30
The inside chain plates for the waterstays are made in 6 x 40 mm galvanized steel. Over many years, this has shown some weakness due to corrosion combined with the fact that these boats over time are heavier than originally designed. Thus, structurally, we strongly recommend changing these chain plates to 8 x 40 mm stainless steel quality.For the same reasons, we strongly recommend changing the smaller outside four waterstay hull chain plates, which originally was made of combined 6 and 12 mm stainless (welded). We recommend that these chain plates should be made in one solid 12 mm chain plate, and, installed with 3 x 12 mm strong quality bolts (A4/316 – strength 70 or 80).

Rigging

Visual check of all cables is still required when changing the rigging. When trailering the boat, 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 Dragonflys, please regularly check the forestay cable in the top by the terminal. When furling, the spinnaker halyard may block the forestay, which can cause failure of the forestay.

Trampolines

On all Dragonflys, we recommend re-stitching (sewing) along the seems 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.

Float deck Teflon pad rings

On Dragonflys built after 1989, the white 5 mm Teflon pad rings on the float deck need 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.

Quick-links

Over the years, Quorning Boats has used the riggings links, so-called Quick-Links, in the Dragonfly production. 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.

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.
