with Sailinjay. In addition to control of the boat, it is much easier to feel the boat when underway. I, too, have a '79 Catalina 30 and basically use mine when in my slip and if I have to go onto the cabin and raise/lower the mainsail when singlehanding and I am either too lazy to set the auto pilot or I forgot to turn it on!!
