All boats are a compromise...
I once heard a great description about the MacGregor 26X-"As a sailboat, it makes a great powerboat. As a powerboat, it makes a great sailboat." In other words, It will do EITHER power OR sail well enough to cover its bases, but it does neither well enough to be called 'exceptional'- Especially when you need one capability over the other (rough weather, or no wind). What makes the Mac 26X unique is that it tries to be a little of each- there aren't many (any?) other manufacturers that even try to create a boat like this. Most will lean towards either sailing or powering capabilities, using the other as an 'auxiliary' means of propulsion. My advice would be to determine which you and your daughter are more interested in- A motor vessel or a sailing vessel- by spending a little time aboard a variety of each. After some time on each kind of boat, I suspect you will find one sport more enjoyable than the other, and you can develop some criteria for the style of boat you should shop for. If you're looking for time on various boats, you can almost always find people at local sailing clubs / Power Squadrons / boatyards / Marinas that will be willing to give a tour of thier boats, if not a quick 'orientation ride' if you smile and ask nicely (or donate a few beverages to their cooler). As an alternative to a Mac 26X, how about looking into a small multi-hull boat? Speed, stability, light weight, shallow draft, and sailing capability all rolled into one, may just be what you're looking for. The first thing that pops to mind is a TomCat 6.2 (I've included a link below). It's not quite as easy to load onto a trailer, but may better suit your long-term need for speed and comfort in a ~20 foot, trailerable package. There are several other small cat's that can also fit the bill...(Eep, I'm a die-hard Hunter owner, and I just recommended A Different Brand!
