Like Dave K. I'm wondering what "less comfortable ride" means.

However, it may also be worth defining what "solid secondary stability" 
means.  Secondary stability really doesn't have anything to do with staying 
vertical but is more the amount of resistance to a complete capsize when 
the hull is "on edge".  From paddling lot of different boats I find that 
how far one edges the boat to get to a secondary stability point varies 
greatly.  I also find that the transition from a primary stability point to 
a secondary point can be even of greater importance than how "solid" the 
secondary stability is once you get there.  It's especially noticeable in a 
hard chined boat where the primary stability feels a bit twitchy, but once 
the boat is edged way over it feels stable.  On my soft chined VCP Skerray 
it feels since and stable sitting vertical and feels like it transitions to 
it's secondary stability point gradually.  Finally, I've paddled some boats 
don't take much of an edge to get to a solid secondary point, but the boat 
can edge past it easily and unless you've got a good brace, there's nothing 
left to prevent a complete capsize.
