Would it be fun on a Prindle 16 at 8 knots?
With 8 knots the Prindle 16 by far beats the Hobie 14T.
As far as the uprighting business; you can find on this forum a lot of threads (topics) regarding this subject.
The moderator of this forum sales a special pole-system for this problem.

It's just something you have to investigate and learn as a necessary manoeuvre.
