I have a Nacra 6.0 and can put the wheels under the boat by myself. I lift one side of the wheels and put the low side under the hull and us the wheels as a fulcrum lifting the boat. This allows me to slide the other side under and then I use my foot on top of the tires to push the wheels the rest of the way. When balanced I can push my boat the 175 feet to the waters edge by myself. When returning because we normally have an incline due to the surf and tide, I will leave my jib on as an aid to getting the boat back up the beach, and it will take two people. We have an onshore wind 95% of the time. By the way I am 63 years old, if I can do it, so can you.
