4.0   RIGGING 

 
4.1 General 

Description 

 
In order to tune your mast effectively, it is important that you are familiar with the basic associated 
principles.  Some definitions and explanations follow:  The term 'standing rigging' refers to fixed pieces 
of stainless steel rod or wire supporting the mast.  Those, which offer fore and aft support, are called 
'stays' (backstay, forestay, etc.). Those, which provide transverse support, are called 'shrouds'.  
 
The shroud running from the masthead to a chainplate on the deck near the rail is called the main or upper 
shroud.  If it were to travel this route directly, the angle of support would be so fine as to induce 
extremely large tensile forces in the shroud and equally large compressive forces in the mast.  To increase 
this angle of support, a spreader is positioned according to load requirements.  This spreader should be 
angled upwards to bisect the angle formed by the shroud as it bends over the spreader tip.  A horizontal 
spreader, or worse still a spreader angled downwards, is dangerous.  The spreader may be forced to slip 
further down the shroud resulting in the loss of the spreader and possible collapse of the mast. 
 
The spreader becomes a compressive member, and when properly loaded tends to push the middle of the 
mast to leeward.  To eliminate such a leeward bow, a lower shroud is installed running from the mast at 
the base of the spreader down to the deck near the upper shroud chainplate.  The primary purpose of the 
lower shroud is to provide athwartship support.  The addition of the spreader and the lower shroud means 
that the mast is supported at more places transversely than fore and aft.  Therefore, the mast itself need 
not be as strong transversely as fore and aft.  The mast then may have a lesser (more aerodynamically 
advantageous) transverse dimension than fore and aft dimension. 
 
4.2 Spars 
 
Based upon the relationships described above, the more spreaders and shrouds used transversely, and the 
more intermediate forestays and running backstays used longitudinally, the smaller the allowable mast 
section may be. This can be advantageous as weight aloft and windage may be reduced in addition to 
minimizing the undesirable aerodynamic effect of the mast on the mainsail. The smaller the mast section, 
the less disturbed is the air flow across the main.  However, a practical and functional balance of rig 
complexity and aerodynamic efficiency has governed the design of the rig of the Tartan 4100.  The spar 
section and carbon fiber laminate schedule have been engineered to provide a strong, stiff and safe mast 
while minimizing weight aloft.  
 
Tuning involves adjusting the tension in these shrouds and stays so that the mast will remain straight in 
most sailing conditions with an appropriate amount of rake for comfortable helm balance.  Tuning is 
carried out in two phases - tuning at the dock and tuning while under sail. 
 
4.3 

Tuning at the Dock 

 
All turnbuckles are equipped with toggles at their base, which eliminates bending load on the swage and 
turnbuckle threads.  Toggles are fitted to both ends of the forestay.  As the boat tacks and the headsail 
loading varies from side to side, the forestay terminals are subject to extreme fatigue loading. 
 
Start tuning the spar by ensuring that the mast is in the center of the boat, perpendicular to the designed 
transverse water line.  Your boat may not sit level at the dock due to distribution of gear, stores and 
tankage levels, so check the water line position both sides.  Then slacken the lower shrouds completely by 
undoing their turnbuckles.  Take the main halyard and lead the shackle end to a point on the rail or 
chainplate.  Adjust the halyard so that the shackles just touch the reference point on the rail or chainplate 
with a given downward tension, and then cleat the halyard.  Then take the halyard to the same reference
