Of course, no boat is perfect, so here are the downsides:
1. Footpegs instead of a bulkhead. They make the boat lighter and probably help keep the cost down, but I really think bulkheads are safer and more comfortable for WW boats. The rest of the outfitting is a kid-scaled version of LL's "Bad Ass Outfitting," and it's aptly named. Best seat/hip brace/thigh brace setup on the market.
2. Liquid Logic needs to make a Remix 42 and a Remix 52. The 47 is TOO stable and a bit too deep for a typical 6-8 year old, if you want them to feel what it's like to properly lean/edge a boat. Granted, it will be nearly impossible to flip at that size, which I suppose can be a good thing, but your kid will be forced into using bell buoy body leans to edge the boat. That can be a hard habit to break. On the top end, once your kid outgrows the 47, moving into a 59 will be a really big jump in volume and width.
