I have mixed feelings about boats like the Wave. But for a novice it is a different story.
When I take novices on my Tornado, I get " that was fun"
When I take novices out on my wife's Wave, I get, "that was fun, thanks for letting me sail the boat, where can I buy one".
Boats like the Wave are great for learning to sail. They are easy to rig, sail, and right. So you will sail them a lot. That is the key to learning to sail, time on the helm.
Only when you have had problems with a larger boat will you understand the confidence that a smaller boat can inspire. You know you can drop and raise the sail by yourself on the water if you have to. You can right the boat by yourself in almost any conditions. Hell you are fairly certain you could pick it up and carry it ashore if things get really bad
