I just know that at this time I would really like to get a tandem to take my wife out in, but cannot consider a Hobie because of fit ( at this time I am not looking to get an inflatable, which is more adjustable.) With a standard SOT tandem, I can find a way to make my legs fit, but with Mirage drive, those options are eliminated.
I'm sorry you cannot fit into the Oasis.
It is a great kayak for those of average height. My wife and I have had many memorable adventures in ours!
You should fit into the Adventure but that only seats one. The AI with tramps has allowed others to take their wives along as long as the pair of you are within the carrying capacity.
If you can delay your purchase until the end of the month, the future of the new tandem AI should be clearer. This kayak may fit you better.
On the AI forum I note with interest that for the first time Matt Miller has not issued a denial, as in previous years but has come up with a wait and see statement:viewtopic.php?f=44&t=12917
This coupled with the many videos and pics of the prototypes we have seen must mean we are closer to a release?
At least that's what I am hoping!
