Indeed you can! You won't break speed records, but the Getaway really moves with very little wind. That's one of the reasons I love the Getaway: I can take it out by myself in the morning when everyone is still slumbering, and then take the whole gang out in the evening for a social cruise. Get it with the wings (this boat should never be sold without them!)
I can't compare the setup as I've never tried the Wave, but I can setup the Getway by myself from the hard to sailing in about 20 minutes.
The Getaway is so forgiving, it's a great boat for beginners. If you've ever sailed the 16 and remember the white knuckles as the boat pitched-poled, the Getaway will be a dream. The boyancy in the bows really make a big difference. The boom-less main is a boon with kids (I no longer have to worry about a kid getting wacked by the boom). The foward trampoline is a child's dream.
Just get it, you won't regret.
