What a nice sweet little boat! Especially good for beginners as it has nice primary stability, as well as lots of secondary stability. I got this for my wife in an ultra light kevlar layup. Under 40 lbs so she can walk it around by herself. And she feels confident out on the water. My Prism was a little too much for her. The speed of the boat is quite good as well. And I like using it in small streams and rivers with lots of twists and turns as it's pretty maneuverable.
With almost no rocker, it won't turn quickly enough for anything more than an easy Class II -- remember, this is a cruiser. (I'm a Class III boater, but there are different boats for that.) It has plenty of tumblehome for efficient stroke mechanics, and sufficient volume for camp-cruising up to a week or so. It does weathercock some, so crossing large lakes in high wind can require a lot of effort. But it's very dry in waves and chop, with enormous primary and good secondary stability.
In the all-Kevlar layup, it is wonderfully light and easy to carry on one shoulder, but it's not made for rock bashing.
The Solitude was never a popular boat (Wenonah sold a lot more Prisms) and hasn't been made in many years, so if it suits your style of paddling and you find one in good condition, don't hesitate!
Would I buy the boat again? I did.
