PRE-LAUNCH OBSERVATIONS
5.1
Risk of Loss of Stability
The working sail plan should be reduced if the average wind force
exceeds force 4 on the Beaufort scale. Particular care should be
taken in gusty conditions.
This boat may capsize and remain inverted if excessive sail is carried.
It is designed not to sink if this occurs.
To right the boat. Make sure the gennaker is furled up. When the
boat has capsized and is upside down, undo one (not both) of the
inspection ports in the rear of the float allowing the water to enter the
float. This should take under 2 minutes. When the float is full of water
(has no buoyancy) put you body weight on the centreboard and the
boat will right itself. When the boat is upright get back on board on
the side with buoyancy and let the water drain out of the float. After
the water has flowed out of the float do up the inspection port again.
This sailing boat is intended to be recovered after capsize. The
minimum crew mass needed is 60kg, and the following technique is
recommended
Caution
Stability can also be adversely affected by sloshing fluid. Bilge water
should be kept to a minimum
Information This boat has been assessed as being capable of supporting the crew
even when swamped.
Warning
The boat should never carry more than the manufacturer's
recommended load. The load should be suitably distributed, bearing
in mind that stability is most significantly reduced by any weight
added high up in the boat
The stability and buoyancy of this boat has been assessed on the basis of the weights specified
in section 3.2.3.
Caution
The stability of this boat is significantly reduced at speeds above
displacement speed.
Caution
Stability may be reduced when towing or lifting heavy weights using a
davit or boom.
Caution
Compartments marked as being air tanks should not be punctured.
Caution
Breaking waves are a serious stability hazard
