Brak—
While you might be able to reach back and steer the outboard on a Corsair, it isn't generally recommended and difficult to do in heavy weather. The outboard on the Telstar has a linkage to the tiller that is engaged by slipping a pin into the tiller stock. This allows the TILLER to steer both the rudder and outboard. IMHO, what the Corsairs have is not really a steerable outboard. Most Corsair owners I know have the outboard locked in the centerline position.
As for the Telstar 26, I would agree, that if you need to fold it in the water, it will probably be an issue. I don't remember the specifics of the Contour's folding system, but I don't believe it would work for you, given your specific requirements.
Have you looked at the Compac series of sailboats. Some of their boats have fairly shallow drafts and the prices are far more reasonable than most of the multihulls.

Specifically, the
Compac Eclipse comes to mind, which has a board up draft of 1.5', only a couple inches deeper than the Telstar or Corsairs. At 21' LOA, it is big enough to have the room you need and the facilities you need.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
