You will need to have a appropriately tuned rig. Boats which have poorly tuned rigs are slower, level decrease, heel extra, make extra leeway and could also be harder to steer. Making modifications could be dramatic on any class of boat. They may cut back crew fatigue, widen the skipper’s choices and enhance their status. Boat worth is enhanced and issues will likely be safer in excessive conditions.
Rig varieties
The Bermudan rig is essentially the most extensively used rig on this planet. It could be break up into two foremost teams: the masthead rig and the fractional rig. The masthead rig is comparatively simple to tune however much less ‘tuneable’ than a fractional rig. The fractional rig, in the meantime, is extra ‘tuneable’ than a masthead rig however extra demanding to tune after which hold nicely tuned.
(Left) Use the halyard to gauge the distances from the highest of the mast to both aspect of the deck. (Proper) Measure the gap between the mast and the vertical halyard
Sideways tuning
Make sure the boat is upright and the wind is mild. Arrange the mast on the boat and frivolously rigidity the cap (higher) shrouds, backstay and forestay till the mast is standing pretty upright. It’s price noting that if it’s a keel stepped mast, the chocks shouldn’t be inserted within the mast ring but. If the increase is mounted, let it relaxation on deck to launch the topping elevate. The decrease shrouds and inside forestay (babystay) must be unfastened.
Discover two fastened factors, e.g. on the toe rails or gunwales symmetrically positioned throughout the boat. Test that these factors are equally distant from the mast at deck degree. Then begin measuring with the halyard. If the distances are unequal, tighten the rigging screw on the aspect with the longest distance. When the lengths on either side are equal, the mast is upright.
Many yachtsmen do that test by eyesight. It could be adequate, however requires an upright boat. The halyard test is best if the boat is symmetrical. Lastly hand tighten the cap shrouds with equal numbers of activates every rigging screw and do the halyard measurement once more.

Adjusting the mast rake
The mast is often set with a slight aft tilt – the so-called mast rake – which is able to assist enhance the boat’s upwind efficiency. Mast rake is often between 1-3 levels. You possibly can alter mast rake as follows:
- Trim the boat upright
- Measure the b-value utilizing the halyard as a plumb bob. It helps to connect a heavy object (e.g. a shackle or a wrench) to the top of the primary halyard to measure b (the gap from the mast to the vertical halyard). Inserting the halyard’s weighted finish in a bucket of water will dampen the oscillations.
- Alter the forestay and backstay rigging screws to set the specified rake. With a fractional rig, use a working backstay as a substitute of the backstay when adjusting rake.
