You used to be able to buy a special blanking off kit from Avon in the early 1990's.
We made our own which basically consisted of a shaped bar that fitted in the front holes that was threaded each end. Into which we put bolts in with rubber and metal washers to make it water tight.
So they did up against one another.
In the stern we had a stainless plate with a normal drain bung fitted, this had a stainless bolt through it, which screwed into a threaded hole in a stainless bar behind, which went inside and was wider than the hole, so it just pinched the plate against the stern.
I dont know how clear that is but it can be done!!
