36 COACHING FUNDAMENTALS Above: Casually adjusting your boom height can throw your outhaul setting out, so any boom height change must be matched by adjusting the outhaul A way of visualizing this is to imagine a plank leaning against a wall. If you take the plank and push it higher up the wall then the lower end of the plank will move towards the wall therefore the distance between the wall and the lower end of the plank is reduced. Knocking the boom upwards from the middle of the cutout reduces the boom length in the same way which effectively pulls the anchor point for the clew of the sail closer to the mast, which reduces the outhaul tension. This works in reverse as well: if the regular sized guy (now rested) takes the same rig from the tall lady when she comes in (assuming that she attended to her earlier problem by extending the boom and setting the outhaul correctly) and then knocks the boom back down to the middle of the cutout then he will effectively force the back end of the boom out (like sliding the plank back down the wall). Now he will have so much outhaul tension that even the five finger press might be impossible and this brutally over-outhauled sail will feel as flat and lifeless as Wile E. Coyote on a canyon floor under an Acme anvil… and if your sail is flat like that it will feel horribly twitchy. If you tune your rig in the order above you will never have this problem but, if you do have to raise or lower the boom for any reason after setting the outhaul, you must re-check the outhaul to see if it needs adjusting. Mastfoot position adjustments Now that we have our mastfoot on the mark we made on the mast track, we need to consider what circumstances might uk WIND SURFING require us to move it forwards or backwards from this standard position. Well it’s a good idea to move the mastfoot forward a centimetre or two when struggling to get going because you are a bit heavier or are guilty of stomping around a bit on the back of the board when learning to get into the footstraps (especially the back one). If you do move it forward then re-connect your rig and lean it over the tail and you will see that the boom is now further forward than your standard setting off the tail. So, to tune everything back to normal, you will now need to put the boom up so it remains on your standard, memorised setting from the tail. And because you have moved the boom up you will need to reset your outhaul. Moving the mastfoot back can bring the board to life if it feels sluggish at planing speed, especially when you are well powered-up (as too much of the forward part of the board was being forced into the water creating drag). And if you move it back a little then that will require you to lower the boom a little to align it to your standard setting off the tail. And, once again, because you have moved the boom you will need to reset your outhaul. So, if you move your mastfoot you then need to adjust your boom height and then reset your outhaul. These simple adjustments are easy, take only a few seconds and tune your rig right back to where it needs to be. Failing to make them can de-tune your setup which may impair your technique and, therefore, your ability to succeed and/or progress.
