If the shaft rotates irregularly, it could be that some rollers have developed a flat side. This will
have been caused by a temporarily blocking of the rollers by dirt parts. In most cases this will
have been caused by dirt falling in from above on open tube systems. Please use a gaiter to
prevent this in future. The exchange of the rollers is quite simple: the internal part of the bearing,
the so called ball with rollers can easily be removed by rotating it 90° and pulling it out of the
groove. A light film of grease should be between the ball and housing.
No grease is allowed inside the bearing, between the rollers.
The top bearing doesn’t need any maintenance. It should yearly hose it down to wash away any
sand and dust between the rollers and the housing.
The vertical locking mechanism should be inspected yearly for any signs of movement relatively
to the shaft.
Appropriate measures must be taken to prevent damages to the fuel conduits.
Equipment that contains petrol may not be stored in areas that are
not meant for it!
4.8. Winter storage
Winter storage is the time during which your boat is left unattended for a longer time. During this
period it must stand securely and should be stored in a place protecting it from atmospheric
effects.
Dispose of all waste.
Remove all sophisticated equipment from the boat. Cushions should be stored in dry, ventilated
and frost-free places.
If the boat is covered by a tarpaulin, you should ensure that the air can circulate well underneath
it. If possible, keep the ventilation apertures of the boat open.
The tarpaulin should be well fixed so that no abrasions cab take place especially the hull.
4.8.1. Hull and deck
Clean the yacht immediately after hauling. High-pressure-cleaner can remove all fouling.
For boats sailing in seawater: remove all rests of salt, because it can speed up the corrosion.
The boat should only be cleaned with fresh water if possible. Environmentally compatible
cleaning agents suitable for FRP and varnished surfaces may be used for persistent dirt.
Special agents are offered for further treatment such as refurbishing and sealing varnished
surfaces. Only use agents suitable for this!
Metallic parts may only be cleaned with metal polish. Please note that aluminium parts are
anodised and must not be treated with scratching or polishing agents.
