2.9 HAULAGE AND LAUNCH

CAUTION

The lifting method depends on the type of lifting equipment adopted therefore it cannot be suggested.

CAUTION

Before haulage and launching check: that nobody or unexpected material is on board and that materials are properly rigged and locked.

WARNING

Hauling and launching operations have to be carried out only by qualified personnel and in special shipyards and under their direct responsibility.
CUSTOM LINE declines any responsibility for damages to things or persons caused by the wrong performance of hereunder listed operations.

CAUTION

Never place the lifting straps in the areas highlighted on the drawing.

• I Lifting equipment must be in a good condition. The lifting straps must not be worn out, and should be covered with suitable protections to preserve the bulwarks gel-coat and the anti-fouling paint on the hull bottom.
• The travel lift capacity must be greater than the yacht weight.
• If only one crane is available, use a “spacer” to give the lifting straps an angle greater than hull width.
• Test the stability of the system, before lifting the yacht, the yacht gravity centre depends on the load and its displacement.
• When ashore, the yacht must be placed on a cradle with at least five supports in the width and with suitable sizes so as to evenly distribute the yacht weight.
• The hull inclination must be as “natural” as possible, e.g. it must be parallel to the waterline and not to the keel. This to prevent that liquids on board keep a normal level and that rainwater can be drained naturally.

CAUTION

If the lifting straps are placed in correspondence of the exhaust ports, pay very much attention and apply provided protections, so as to avoid their damage.

CAUTION

Do not put the lifting straps in way of intakes, of sea exhausts or of other protrusions.
Lifting straps must be positioned according to the loading conditions of the yacht at the moment of its lifting, because these vary remarkably, for instance, when the yacht is unloaded and dry or when the yacht is fully loaded. The lifting straps arrangement must each time be carefully evaluated, in order to prevent any damage to the yacht.

CAUTION

CUSTOM LINE declines all responsibility for the location of the lifting straps, the lowering of the yacht to the ground and the support points carried out in other Shipyards.

DANGER

During haulage and launch, never stay underneath or in proximity of the yacht.

Cradles (Optional on request).
CUSTOM LINE is capable of providing the cradles for a correct support of the yacht (optional on demand). CUSTOM LINE is not responsible for any damage resulting from the use of cradles different from those expressly produced by CUSTOM LINE.

Propping
It is a common procedure to use supporting props if no actual storage capacities are available. It is very important to take some basic precautions while positioning the supporting props for the yacht in order to prevent age to the hull structures, accidental falls of the yacht or injury to the involved personnel. The following list contains useful advice. We also recommend always having propping operations carried out by experienced personnel.

• Use props with adequate strength and stability (each keel prop must support at least 1/5 of the whole weight of the yacht).
• Use correctly dimensioned supporting plates to prevent negative weight concentrations.
• Place the props preferably next to transversal structural reinforcements (stringers).
• Locate the props along the supporting fins of the hull.
• Always place at least 5 props along the keel, 3 props starboard and 3 props port in order to guarantee stability and weight distribution.
• Start positioning the three keel supports along a straight line, appropriately spaced to distribute weight.
• It is important that the props have the same height in order to prevent that the load is concentrated mainly on one of them.
• Have the yacht lowered very slowly until it almost touches the keel props, adjust the height of the props until they are in contact with the keel, in order to guarantee a uniform load distribution and a neutral trim of the yacht; keep part of the weight supported by the crane.
• Position the adequately spaced lateral props; it is important to remember that the lateral props must guarantee stability, but the whole weight must be supported mainly by the keel props.
• Check the support for stability, then completely lower the yacht and remove the belts.

The suggestions above are to be considered as being generally valid for propping the yacht without damaging it or harming the personnel involved; however, since the propping conditions may significantly vary depending on the props used and the surface on which the props rest, the above suggestions must be adapted case by case.

CUSTOM LINE is therefore not responsible for any damage to the yacht occurring while the yacht is at dry shore on props.

CAUTION

CUSTOM LINE declines all responsibility for the location of the lifting straps, the lowering of the yacht to the ground and the support points carried out in other Shipyards.
