- Put it slightly under tension ; the sling hooks should be situated at
the boat's centre of gravity,either in the longitudinal centre or
plumb with the shroud chain-plates in the transverse plane.
Hoist gently,and control the movement of the boat with dock lines.
• AFTER LAUNCHING
- Check the sounder and speedometer fittings for tightness if need
be.
- Open the valves and make sure that they are tight with the hull and
relevant hose.
Before starting the engine, refer to the MOTORIZATION chapter.
If later you have to step the mast anywhere other than at your LA-
GOON dealer:
• BEFORE MAST INSTALLATION
- Protect the mast against possible chafing by the crane hook and-
cable.
- Tie down the shrouds and all the riggings to the base of the mast
with a lashing long enough to guide the mast heel when stepping
the mast.
- Protect the spreader end fittings and the roller furler drum.
- Put a rope of about 1,50 with an eye and thimble at both ends and
covered with rags round the mast. Place the rope under the se-
cond tier of spreaders.
- Link together both thimbles (that are ahead of the mast) with a
shackle large enough to receive the crane hook.
- Raise the whole till it is taut under the spreader bases.
• DURING MAST INSTALLATION
- Take the necessary steps to avoid damaging the mast head equi-
pments.
- Use the backstay and lashing at the base of the mast to control the
handling.
- Engage the electrical harness in the mast base.
- Make sure the base of the mast integrally bears on its base plate.
DANGER
Do not stay on board or under the boat during hoisting.
RECOMMENDATION
Never place belts or fenders in contact with the large glass
windows in the hulls.
