I don't know the dimensions but the v-berth should be plenty roomy for 2. I'm 6'2" and the length is ample, as is the width and overhead clearance.
The port settee folds out to make a nominal double, too, though you have to unbolt the center table for clearance.
The original advertising even claimed that you could convert either quarterberth into a double by adding a drop-in board at the inboard corner. That might be a little tight, but they are pretty cavernous. I can almost sit upright in them.
They are pretty roomy boats.
