Sailing a fully foiling craft is a hazardous sport, with many 
disciplines and ability levels. As with all sports, there are 
inherent risks of injury. The following contains key points 
to remember when operating your Nacra FCS craft: 

 

Be familiar with the Nacra FCS deck lay-out, trim and 
control systems.  

 

Make sure the trim and control system are rigged and 
used according to the supplied instructions, as written in 
this manual as in the assembly manual. 

 

Make sure your Nacra is maintained well and in good 
order, a frequent inspection of the Nacra should be 
made in order to identify punctures, tears, cracks or 
abrassions of the composite foils, metal fittings, ropes 
and their knots. Make sure all shackles, bolts and nuts 
are securely fastened at all time.  (see Maintenances for 
more information) 

 

Do not lend your Nacra to someone who has not been 
fully instructed on the use of this sailing craft. Other us-
ers should also read this manual and be proficient in all 
its points. 

 

Check your gear before going on the water. Insure that 
all systems are rigged properly and are in working order.

Fully foiling is the term 
used to define the condi-
tion when the weight of 
the Nacra FCS including the 
weight of the crew  is fully 
balanced on the lift pro-
duced by the foils (e.g. the 
Daggerboard and Rudder) 
or both hull are completely 
out of the water and flying.  
 
Approach your first fully foiling sessions in steps to get famil-
iar with this product: 

 

Do NOT sail your first ten  (10) sailing sessions in wind-
speeds of 15 knots (28 km/h) or above.

 

 

Sail your first sessions in flat water or calm seas 

 

 

Take time to get familiar with fully foiling and start with 
both crews sitting on the deck of the windward hull be-
fore you go out on the trapeze.

 

 

Learn to understand how to react with steering in the 
transition zone between non foiling and full foiling.  

 

 

When both crews start trapezing begin to stand high in 
trapeze to prefend you don’t get washed away from the 
boat (Tea-backing) by a wave or when the boat heels to 
windward with the leeward hull still flying.

CAUTION!

 

Make sure the surface area is always as smooth as 
possible, particularly the elbow element region of the 
Daggerboard. As a rough or damaged surface (paint 
damage) could easily  induce ‘ventilation’ of the foil in 
Full Foiling mode. When the foil ventilates the pro-
duced lift will reduce significantly causing the boat to 
drop out of Foil Foiling mode quite aggressively.
