The Keel  

 
The Open 500 is equipped with a keel (more 
than 90 kg) entirely retractable into its casing. 
 
When the keel is in the low position, (draft 1,58 
meters) a trap door covers the keel casing.  
When the keel is brought up, the trap door is 
retracted. This action of the trap door is 
automatic. A bail system helps to empty the keel 
casing when the speed of the boat is sufficient. 
 
The keel is raised and lowered by moving the 
loop of rope which activates the sheave which 
notches into a threaded rod. It is this threaded 
rod which moves the keel due the movement of 
the bronze part( located inside the upper part of 
the keel). 
This loop of rod goes all along the keel casing 
through the  #348 pulley fastened to an elastic 
at the rear of the boat ( see picture 2.) 
When the keel touches the sea bed, or the 
lowering control is activated but the keel is 
unable to go down (beached or on the trailer) 
then it is only normal the mechanism "slips out" 
and that the threaded rod appears.  
To put the system back in working condition, it 
may be necessary to activate the threaded rod 
the in the same way as raising the keel before 
going afloat, while still holding the keel.  
 

Never put hands or fingers into the 
mechanism

.  

 
It is imperative to regularly lubricate or oil the 
ball bearings, the stainless steel nuts and its 
spring, as well as the threaded rod and bronze 
part (by the trap door).
