Absolutely true.  It seems that whatever anyone tries WRT stabilization
(even sponsons) you get the same kinds of problems.  It's better until
something goes wrong, then it's worse.

Dampened stabilization.  Interesting idea.  

Just between you and me, I don't think anyone could get a gyro-stabilized 
kayak to work.  Without doing the numbers, I suspect that the weight of
the gyro would be prohibitive compared to the benefit (if not the weight,
then the spin velocity required).  

However, the experiment for a student is a valid one.  One thing that 
bugs me about this from my science fair days is a bias, conscious or 
otherwise, on the part of examiners to downplay the value of a negative 
result.  That is, they seem to put more value on a result that shows 
something works than one that shows something doesn't work, even though 
scientifically these outcomes are equally valid.  

Given this, perhaps Robert and his daughter should focus on showing 
the _effects_ of a gyro on a floating object (kayak or other) rather 
than trying to show a benefit.  A subtle difference, but meaningful 
in presentation.
