Hi Mat,
sorry to say that according to the philosophy of the 18s there are no halyards for main and Jib normally. You hang in the sails and put pressure on the forestay using a "boat breaker"-called block and tackle, pulley. That means you you have to lay over the boat ashore and go out completely rigged. There is only one boat worldwide that has halyards (Werner Gieser, Germany, Team Wet Protect) but he uses it after pulling the power on the rigg with naked forestay to put up the sails also ashore (no way to do it on the water, maybe you could put sails down on the water but how to manoever than to the safe beach? The boom will block your rudder as well as it is rather unstable and 10 meter rigg will push you simply square unable to steer).
Without wings? absolutely no, for you stabilize the wings with wires to the front and connect them in the back. No way to carry them onto the water and put them in later. Moreover I wouldn't dare to stand on them without wires (the whole pressure is loaded on the wingsupports alone -> chance of breaking).
Better look for a wide ramp or a beach to launch.
Hope that helped you
