Regular maintenance 

For a private use, we have chosen to stress on the main aspects of the maintenance of your landyacht. 
Even if this list seems to be obvious for you, as you may know, a regular maintenance is paramount for a 
safe and reliable operation of your landyacht given you may use it mostly on a beach. The following check-
list helps you to keep your landyacht in a good state.  

-

 

Check any tightening’s (frame, tiller, axle 
support, axles, front fork, spindles, wheels 
steering fork...) before each session; 

-

 

Only if you hear a noisy ball bearing, check 
its lubrication and whether it is needed, add 
some grease into it (open the gasket with 
the tip of a knife, and press back the gasket 
with your inches). Should the bearing still 
making noise, then you can change it; 

-

 

Wash (with clean water) the landyacht after 
each use; 

-

 

Regarding stainless steel components, if 
you detect incipient rust, it’s not a big deal 
as it is well known that in certain 
circumstances, such as beach conditions 
(mixture of salt and sand), even stainless 
steel may experience some minor 
corrosion. To clean this rust, use an 
abrasive sponge, as this corrosion is only 
superficial; 

-

 

Check the steering system, if the fork pivot 
makes noise, just add a drop of oil ; 

-

 

As concerns the mast, check on a regular 
basis the red adjustment strips and 
reinforcements. Any degraded mast 
location should immediately be replaced. 

For a smart operation

  

For an easy start and easy 
piloting, using the dogvanes 
(also called “telltales”) stuck on 
the sail is highly recommended. 
Dogvanes are short wool 
strands you can see close to the 
leading edge of the sail (picture 
38). The air flow is laminar 
when the dogvanes are 
horizontal. You need to focus 
first on the extrados dogvane, I 
mean the one behind the sail, 
the one you can see through 
the sail.
