Re: Rig & Sail Fine Tuning
Hi Alan, yes as you found out the hard way, fine tuning is the difference between being at the front or somewhere back in the bunch.
It is an acquired skill which can be learnt by anyone although some will always be better at it, just like life really.
In a yacht the size of an IACC 120 a keel stepped mast with a ram is a huge advantage.
The ram controls the lower half of the mast fore & aft curve, which in turn controls the draft position and depth of the lower portion of the main.
There is an alternative if you wish to retain the deck step and that is to fit a deck mounted ram.
Either way, some method of controlling that section of mast is essential.
The next question comes with the control of the top section of the mast.
Should one use jumpers for this or are they simply adding windage and weight where it is not needed.
I personally am a jumpers believer. They allow you the luxury of making the choice with the draft position and depth again.
Next we come to mast material and the shroud set-up.
I have just been away to check that any material may be used for the mast construction.
That pretty well tells me that carbon fibre is the only way to go if you are serious about having the fastest 120 on the planet.
How big a diameter, wall-thickness, section, taper, straight, groovy, round, aerofoil, luff wire, tie-on, etc, etc, these are some of the options a builder has to choose before the question of rigging is considered.
Perhaps I should stop here and allow you to answer some of the questions I have posed here and to ask some more from the many thoughts that you must have.
Others will also have much good advise on this most excellent forum.
Best wishes from middle earth.
