Sure you can have the apparent wind abeam in any vessel. You just need the true wind to be at an angle whose cosine is the negated ratio between boat speed and true wind speed (assuming my trig is correct).

I would say that even in that case you could have both sails operating in clean air, if properly trimmed.
