MAST CAREUpdated a year ago

Point loading is the first enemy of the mast
Always protect your mast from impact damage or point loading. Carbon is very vulnerable to impact damage. Even if there is no visible damage, the mast may be seriously damaged if it is dropped or knocked, which will, when put under load, result in breaking. For storage, transportation or simply whenever not being used, ALWAYS store your mast in a protective mast bag.
 

Sand is the second enemy of the mast
Before rigging up please make sure that all your rig components (mast extension, mast top and base, mast sleeve, cambers, boom front-end) are absolutely free from sand and grit.
If you don't want to end up with a one-piece mast (no joke) please always make sure not to have any sand inside the top part or on the connection joint of the base when putting both parts together. If you want to be on the safe side secure the gap between the base and the top using tape.
 

Permanent downhaul tension is the third enemy of the mast
In order to generate maximum performance your mast should be straight when not under tension. However, due to the massive downhaul tension, over time eventually every mast will take a bit of pre-bend. Once this happens it will only get worse as the mast automatically twists into its pre-bend position when downhauling the sail. The only thing that keeps your mast straight for as long as possible is to release the tension while not in use. This means that you should never leave your sail under full downhaul tension overnight.
That's also the reason why bending is excluded from our unconditional warranty.
