SEVERNE MAST CARE GUIDE
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
SlipLok is a texture added to the boom area of SEVERNE masts to increase friction for less slippage. This eliminates the need to overtighten the boom, decreasing stresses on the mast.
The SEVERNE boom with the Lockjaw front end only requires a minimal closing force to attach securely to the mast without sliding. You should not apply more than 10-15kg of pressure to close the lever. This can be done easily with two fingers.
Many over tighten their boom head with excessive force. This can easily crack the mast and leads to permanent damage at the boom head. It’s important to note that breakage at the boom area is NOT covered by warranty.
Overexposure to UV and heat
Leaving your mast under direct sunlight shortens its life-span and increases the risk of breakage. When not sailing for a longer period of time, we recommend moving your rig out of direct sunlight or completely de-rigging it. UV rays are also harmful to your sail.
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 assembling the mast
Make sure the top section of the mast and the ferrule on the bottom section are completely clean before putting the mast together.
When launching in waves/shore breaks, keep your rig clear of the breaking waves. If your rig is caught in the impact zone of a breaking wave, your mast, as well as your sail, could be damaged. Furthermore, if the top of your mast catches the ocean bottom while a wave impacts the sail, your mast and sail could suffer breakage.
Impact with sharp edges or hard/abrasive surfaces might cause permanent damage to your mast or compromise its structural integrity.
The use of an adjustable downhaul system can cause stress and damage to your mast. At the point of attachment, the rope can cause compression onto the fibres of the mast. And while not immediately obvious, the compression on the mast weakens it over time, and causes breakage.
Improper use of cams can create wear on the mast and damage the mast permanently.
Make sure cams are placed well and rotate correctly.
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.
