Actually Catalinas did fly in groups of three many times, although mainly when on rescue missions, but from what I have read they also did some hunting of surface ships at night in formation as well...
They were known as the workhorse of the Navy because of the many different rolls they performed.

I agree Sikboy. However, given that his airplane will be a 2 engine pig (very low speed) with limited armament for defense (these aircraft never flew in formations like the B17s and Ju88s) it would be a very nice and unique advantage to be able to get a successful landing on water anywhere. Also, I very much like the ability to fly these out of ports as well as land bases. Currently if your Port is under attack you need to get there from an adjacent base which is kind of a pain. Having a Cat there to launch torpedo or bomb attacks on a CV would be good.
