Majoni Star Cylindrical Standard Boat Fender

The Majoni Star Cylindrical Boat Fender is a double-ended inflatable marine fender designed to cushion a boat’s hull when berthing alongside pontoons, marina walkways, harbour walls and other vessels. Its elongated cylindrical body can be suspended vertically or horizontally, while the integral attachment eyes at both ends allow the fender position to be adjusted to suit the hull and mooring arrangement.

Majoni manufactures the Star range in the Netherlands from a strong, UV-resistant marine-grade vinyl formulation. Specialist marine suppliers also describe the construction as rotation-moulded PVC. Each fender has reinforced end ribs and a replaceable brass valve for inflation, deflation and ongoing maintenance. Majoni recommends an inflation pressure of 0.2 bar / 2.9psi.

The range covers Star 0, Star 1, Star 2, Star 2A, Star 3, Star 4 and Star 5, with manufacturer-published diameters from 10cm to 30cm, lengths from 40cm to 90cm and internal volumes from 2 litres to 56 litres.

What Is the Majoni Star Fender Used For?

The Star fender is positioned between the boat’s hull and an adjacent surface to help absorb contact and distribute pressure over the fender body.

• Alongside marina berthing
• Pontoon mooring
• Harbour and quay-side berthing
• Rafting alongside another vessel
• Temporary hull protection during manoeuvring
• Vertical protection along the topsides
• Horizontal protection along a wider section of hull
• Leisure, commercial and workboat applications where the selected size is suitable

Which Fender Size Should Be Selected?

The supplier-published boat-length guide provides an initial reference, but the correct size also depends on vessel displacement, hull shape, freeboard, berth exposure, tidal movement, fender quantity and mounting position.

Where a vessel falls between two models or is used in an exposed berth, the larger fender provides a greater diameter and internal air volume.

Are the Boat-Length Recommendations Manufacturer Ratings?

No. Majoni publishes the dimensions, weights and volumes but does not publish a model-by-model boat-length rating in its current brochure.

The boat-length values should be treated as supplier guidance rather than maximum impact, compression or vessel-displacement ratings.

What Is Included?

• 1 x Majoni Star cylindrical boat fender
• In the selected model
• In the selected available colour

Not included unless expressly stated:

• Fender rope or lanyard
• Spliced fender line
• Majoni inflation adaptor
• Hand, foot, bicycle or car pump
• Air compressor
• Replacement brass valve
• Replacement-valve kit
• Fender cover or fender sock
• Fender basket or storage rack
• Additional fenders

Does the Fender Include a Rope?

No. Fender rope is supplied separately. For horizontal installation, a separate attachment line may be required at each end.

Can the Fender Be Hung Vertically or Horizontally?

Yes. The Star fender has attachment eyes at both ends and can be suspended vertically from one eye or horizontally using both eyes.

What Material Is the Fender Made From?

Majoni describes the material as a strong, UV-resistant marine-grade vinyl. Specialist suppliers describe the construction as rotation-moulded PVC.

The exact polymer formulation, wall thickness, hardness, tensile strength and temperature range are not published.

Are the Attachment Eyes Reinforced?

The Star fender has reinforced ribbed ends and two integral rope eyes. No numerical rope-eye breaking load or maximum rope diameter is published.

How Is the Fender Inflated?

Using a compressor:

1. Use a flat compressor nozzle.
2. Press the nozzle against the brass valve.
3. Inflate gradually to approximately 0.2 bar / 2.9psi.
4. Remove the nozzle and check that the valve retains pressure.

Using a bicycle or car pump:

1. Fit the separate Majoni inflation adaptor.
2. Connect the compatible pump.
3. Inflate gradually to approximately 0.2 bar / 2.9psi.
4. Remove the pump and adaptor.

Is an Inflation Adaptor Required?

• Flat compressor nozzle: Normally no adaptor required
• Bicycle pump: Majoni adaptor required
• Car foot pump: Majoni adaptor required
• Hand pump with tyre fitting: Majoni adaptor required
• Needle or pin fitting: Must not be used

What Is the Correct Inflation Pressure?

• Recommended pressure: 0.2 bar
• Equivalent pressure: 2.9psi

At the correct pressure, the fender should be firm but remain visibly compressible when pressed with the flat of the hand.

Can a Needle or Pin Adaptor Be Used?

No. A pin or inflation needle can damage the Majoni valve. Use a flat compressor nozzle or the dedicated Majoni adaptor.

Can the Brass Valve Be Replaced?

Yes. Majoni describes the brass valve as replaceable. The separate Majoni adaptor can be used to remove and refit the valve as well as to inflate and deflate the fender.

What Colours Are Available?

Majoni states that its fenders are available in 12 colours overall. Supplier-listed Star colours include:

• White
• White with blue ends
• Anthracite
• Black
• Navy
• Orange

Colour availability varies by model and retailer.

Are the Published Volumes Correct?

• Star 0: 2L
• Star 1: 4L
• Star 2: 8L
• Star 2A: 13L
• Star 3: 18L
• Star 4: 27L
• Star 5: 56L

These are the current Majoni brochure figures.

Why Is Circumference Not Included?

Majoni does not publish circumference values. The supplier figure of 38cm for Star 0 conflicts with its stated 10cm diameter, so circumference has been omitted from the manufacturer-backed specification table.

How Should the Fender Be Positioned?

• Position the widest part of the body at the expected contact point.
• Account for tide and changing freeboard.
• Use both eyes for horizontal installation.
• Ensure the fender remains between the hull and adjacent surface.
• Check the position after the vessel has settled in the berth.
• Reposition the fender when wind, tide or mooring conditions change.

How Should the Fender Be Cleaned?

• Wash with warm or hot water and soap.
• Use a soft cloth or non-damaging brush.
• Inspect both rope eyes and reinforced ribs.
• Check the body for cuts or splits.
• Check that the valve retains pressure.
