I don't think anybody does. But you can ask Abraxus what he had in mind when he suggested it
That's what I said in post number 10

My seacocks are stainless steel anyway so no advantage.
It is common on steel boats to weld a stainless half pipe nipple directly onto the hull and then screw a stainless ball valve on to that.
If plastic skin fittings and valves were to be used as some recommend I think the same should be done around the plastic seacocks.
I only have duel inlet seacocks that feed a manifold to distribute all items that need a sea water feed. The only other below waterline seacocks are the 2 outlets from the heads. My gally sink and aft head sink outlets have welded standpipes reaching above the waterline so don't need seacocks as such but I do have call valves directly below the sink outlet. The forward head sink outlet is above water level anyway so no real problem.
All outlets weather above or below waterline have ball valves even the engine and generator exhausts.
Belt, braces and a piece of string may be.

Ok, in simple terms I was talking more of a sealed box than a pot. The hose exits the box and this point is sealed.I don't think anybody does. But you can ask Abraxus what he had in mind when he suggested it

The seacoock is one point of failure, and of course the seal on the box is another. However, in order to flood the boat, both need to fail at the same time. So no, it doesn't shift the problem, it adds additional protection, as if only one seal fails then no flooding.

If you have a boat with enough room to carry one, a petrol-driven salvage pump would seem a good idea. It could be quickly deployed wherever on the boat it would do most use, and could be used to rescue someone else if needed. I was thinking of something like this: http://www.machinemart.co.uk/shop/product/details/clarke-pw3-3inch-petrol-driven-water-pump
