A mast can break for several reasons, but apart from production defects, the most common reason for mast breakage is incorrect usage.

Here are a couple of tips on how to look after your mast and extend its lifetime.

Boom head – Do not over tighten

SLIP LOK Textured patterns in the boom area of our masts increase friction for less slippage. This eliminates the need to over-tighten the boom, decreasing stresses on the mast.

Using the SEVERNE boom with the Lockjaw front end, you only need to apply minimum force for it to sit perfectly stable on the mast without sliding.

You should not apply more than 10-15kg of pressure on the end of the lever for it to close. This can be done with two fingers.

Many over tighten their boom head and have to apply reasonable force to close the boom head. This can easily crack the mast and leads to permanent damage at the boom head.

Overexposure of UV and heat

For all masts, leaving them under direct sunlight and heat may damage your mast, shorten their life-span, and the risk of breakage is heightened.
When not sailing for a longer period of time. We recommend de-rigging your sail, move your rig outside of the sun in the shade or release downhaul tension.
UV is also very harmful to your sail – so best to de-rig it or move it out of the sun.


Do not leave your sail rigged

Leaving a sail rigged with downhaul fully tensioned overnight or for several days will damage your mast.
Should you leave your sail rigged, always release downhaul tension.


Before putting the mast together

Make sure the top section of the mast and the ferrule on the bottom section are completely clean before putting the mast together.

Shore breaks

When launching in waves / shorebreak. Keep your rig clear of the breaking wave. A wave breaking the sail may break the mast and/or sail.
When the top of the mast gets caught on the bottom and a wave hits the rig, the mast could break.


Cam usage

Improper use of cams can create wear on the mast and damage the mast permanently.
Make sure cams are placed well and rotate correctly.

Correct usage

The SEVERNE masts, while being very versatile, are designed and built for SEVERNE products using the specs provided. Applying too much downhaul to your sail can lead to damage.
