3. SAFETY INFORMATION
3.1 DESIGN CATEGORY
The Musto Skiff is a Design Category C boat. The definition of this design category is:
•Design Category: C – ‘Inshore’
•Description of Use: Designed for voyages in coastal waters, large bays, estuaries,
lakes and rivers.
•Wind Force (Beaufort scale): Up to, and including 6
•Significant Wave Height, H1/3: Up to, and including 2m
The Musto Skiff complies with this design category, subject to:
•The crew having suitable skill and experience.
•Satisfactory construction and maintenance of the boat and equipment.
Users of this boat are advised that:
•All crew should receive suitable training.
•The boat should not carry more than the maximum load.
•Bilge water should be kept to a minimum.
•Stability is reduced by any weight added high up.
3.2 LOADING
The maximum recommended load for the Musto Skiff is 160 kg and the maximum number of
persons that it can carry is two.
The breakdown of the maximum load is:
Load item Maximum, kg

3.3 SAFETY EQUIPMENT
It is your responsibility to ensure that all necessary safety equipment is obtained and that it is on
board and readily accessible while the boat is in operation.
3.4 CAPSIZE RECOVERY
Risk of Capsize
Capsize is an inevitable part of small boat sailing and the Musto Skiff is no different in that respect.
As a racing craft, there is a high likelihood of capsize if the Musto Skiff is sailed to its limits. You
should practice capsize recovery until you are totally familiar with it.
Capsize Recovery Technique
Should you capsize your Musto Skiff :
•if the spinnaker is up, it should be doused, and the mainsheet un-cleated.
•if the boat inverts, it should be pulled onto its side so that the rig is horizontal. This can be
done by simply standing on a wing and pulling on the centreboard. It sometimes helps to pull
it up with the aid of the wind.
•
After that there are basically two situations to recover from:
•when the rig is lying on the water, pointing downwind;
•when the rig is lying on the water, pointing upwind.
Both methods may take some practice, but they are proven methods to continue sailing after a
capsize.
Rig Pointing Downwind
You should be on the centreboard.
Use the spinnaker sheets if necessary to pull boat upright. When the boat gets to about 45 degrees,
you should climb in, either over or between the wing tube. Endeavour to get hold of the tiller and
mainsheet as soon as possible.

Rig Pointing Upwind
This is quite often the position the boat ends up in, especially if time has been spent getting the
spinnaker down or recovering from the inverted situation.
You should be on the centreboard, holding onto the spinnaker sheets and using them as the righting
line.
As you start to right the boat, the wind will help. As the mast tip leaves the water, you should then
climb into the boat in front of the shroud, walk across the boat in front of the mast to the new
windward side to prevent the boat capsizing to the opposite side.
With the helm on the new windward side the boat is ready to sail off straight away.
Minimum Crew Weight
The Musto Skiff can be recovered from a capsize by a single competent sailor of minimum weight
of 70kg. This has been demonstrated during the testing of the Musto Skiff for its certificate of
conformity.
3.5 AIR TANK
The Musto Skiff is equipped with an air tank to provide buoyancy in the event of capsize or
swamping. The air tank is formed by the hull and deck mouldings and consequently the following
points should be noted:
!Do not puncture the air tank.
!If the air tank is punctured, do not use the boat until the air tank is properly repaired.
If in doubt, contact Ovington Boats for a repair procedure.
!If adding any fittings to the boat, ensure that any fasteners that penetrate the air tank
are suitably sealed to keep the tank watertight.
3.6 MAN OVERBOARD PREVENTION AND RECOVERY
Working Deck and Handholds
The working deck of the Musto Skiff, which is intended to be occupied afloat, is the whole boat
from its aft end to 500mm forward of the area on which the mast is stepped, as shown in Figure 3.1

The designated handholds covering this working deck, which have been tested for strength in
accordance with ISO 15085, are:
•the aluminium wing to deck join ( Aft )
•the aluminium wing to deck join ( Forward )
Crew Overboard Recovery
To recover a crew member from the water:
The MPS is designed to be sailed by one person. Therefore it is recommended that you ensure
adequate safety cover is in attendance before launching.
•The helm should bring the boat just downwind of the person in the water.
•The helm should balance the boat using a combination of body weight movement and sail
pressure.
