not stable enough to stand and balance, but plenty stable to paddle anywhere and climb into off a tall dock - and back on the tall dock
No problem launching here - wouldn't try this with my Kestrel
also able to sit with both legs over one side, which you can't do in the Kestrel at all - it would squirt out from under you
you can also rig the slidetrax really nice for fishing - it's no problem to sit sideways in the boat and reach into that milk crate
here's riding a 35-kt gale wind in a wall-cloud squall with drift sock trolleyed to stern - any boat would capsize you without that rigging - without the stern drag, the wind would instantly spin you sideways and flip you over
one TKF member capsized his Tarpon offshore when he leaned over to pull a bull red into the boat, but he knew what he did wrong and didn't do it that way again.
Here's Neumie standing in an older 29" (and very fast) boat - the reason he can do this is also the drift sock - if he let the boat windock, he's be right over.
Another thing to keep in mind is you'll want a rudder with a T140, but the boat comes rigged to accept one.
The reason my 14' Kestrel doesn't need one is you use thigh straps and lean the boat to turn against the totally slick hull curve, but the Kestrel is built for nothing but speed.
Though I did paddle and fish borrow boats before, I'm on my 11th year with T160 and never turtled it (knock on PE).
There's nothing to keep a T140 from being a Great starter boat.
