An electric impact wrench can be used with screwdriver bits as well as sockets, and will work just fine on slotted head screws.
BTW, PorFin's advice is sound... make sure that you can re-assemble the teak toe rail.
BTW, are you filing an insurance claim against the other boat owner for the damage? If so, you should get an estimate of the repair before doing any work.
They are flat head screws with about 1/2" head. There is no hex shape outer edge to grip a wrench on. From what I can tell, there may not even be a nut on the underside of the deck (which was a little surprising) though it could have supported one. I will see what Home Depot has on electric impact wrenches this evening. So the higher torque will in theory allow the flat head screw bit to turn the screw without stripping? I won't have pictures until I can get to the yard this coming weekend. Its a really nice piece of teak and I have the skills to fix if I can get the thing off the boat. Thank you for the feedback.

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.
