Yes you do, BUT when you sail most heavier uni's, as you are sheet in tight going to weather with speed, As you start the tack, the second you go head to wind you MUST uncleat 2-3 feet of sheet and recleat it as you go to the other side and change the tiller or. Then as you go to a reach heading on new tack, SLOWLY begin sheeting in and heading up. If you DON'T you will go into irons. TRUST me I learned this the hard way. A cat my be different because it is so light?
