This is not going to be a detailed discussion on the stability of small boats. I will actually write something for my website and it will be concise and definitive.
My intent here is merely to commit myself to writing this new page for my web site.
What is prompting me to do it is the persistent mention of secondary stability in kayak and canoe magazines. Three things about this concept.
1) All kayakers use the term as in, "Yeah, I tried that boat. It has low initial stability but good secondary stability."
2) Attempts to find a definition of secondary stability on the internet come up with only a few definitions
3) Such definitions as you can find seem to be subjective and conflicting.
So I will tackle this topic as best as I can.
More to come; stay tuned.
