Thanks for the reply,
I know I'm asking one of those crazy questions, but do you have a
recommendation for what I'm looking for if there is such a beast? Is this
like asking the question... whats the best kayak for white water rafting
Niagra Falls, the best kayak for traversing the North Atlantic and one that
won't capsize during a tidal wave?

It doesn't sound like it will be easy
to find a tandem kayak that can be used by an individual during some what
rough weather.
