The mast should now be checked for rake.
Rake is the angle, either forward or aft, from vertical. Forward rake is to be avoided.
In calm conditions, if possible, hang a weight on the main halyard shackle and suspend it just
above the deck. The distance from the aft face of the mast to the halyard represents the
amount of rake and should be approximately 8"-10".
Rake is adjusted by moving the masthead in the required direction by use of the turnbuckles on
the backstay and forestay.
If your yacht is fitted with a furling gear on the forestay, it may be necessary to adjust the length
of the forestay by the use of linkplates.
Backstay tension should be high, to minimize forestay sag, without imparting too much fore and
aft bend in the mast.
(b) Tuning While Sailing
Select a day with steady winds, around 10 knots. When sailing close-hauled, sight up the luff
groove of the mast. If the mast falls off to leeward in the middle section, luff up and tighten up
on the windward lower and intermediate turnbuckles as necessary, noting the amount of
adjustment. Tighten the leeward lower and intermediate turnbuckles by the corresponding
amount. Sail close hauled on the other tack and check the luff-groove again. Repeat this
adjustment as necessary.
Your rig is now basically tuned. As you become more familiar with the yacht and her rig you
may want to do some find tuning. This may involve changing the amount of rake to optimize
weather helm, or imparting a limited amount of mast bend, by adjusting the relationship between
the fore and aft lower shrouds.
Remember that with a new boat the rig will "settle”
and some stretch will take place. It may be
necessary to recheck and repeat the tuning sequence. Ensure that all turnbuckles are pinned
or locked when tuning is finished.
7. POWER PLANT AND TRAMSMISSION
7.1 Engine
A Westerbeke W30 or W33 with Paragon hydraulic gearbox close-coupled to a Walter RV1O V-
drive with 2:1 reduction ratio. For full details of the engine please refer to Westerbeke Technical
manual sent out with every CS 36. Read this manual carefully.
Engine Compartment Ventilation
An air exhaust blower is fitted to exhaust hot air from the engine compartment. It starts and
stops when the key is turned to “on" from the "run" position. The air is exhausted via flexible
trunking through a vent on the after side of the cockpit coaming.
