Regarding the absolute need to get access to the hull for a pump Ribs have been designed not to require this. If something serious happens your hull then you will be relying on your tubes, you will be in some sort of an emergencey and won't be hanging around. A bilge pump probaly won't make much difference.Better get the problem solved.
I take your point about cutting holes in the hull, and about how useless a pump would be if you got a really big leak. And as you say, the tubes should always keep you afloat.
Nevertheless, my hull is hollow and keeps filling up with water when I leave it afloat. It may not have been designed to need bilge pumping but it does!
Since yesterday I've now got a completely new hull drain fitting and screw bung so I'm hoping the whole problem's been cured. If the water's still getting in, I'll try your deck flooding technique, but I'm not sure it will help in my particular case. I'm pretty certain my leak is under the waterline. The sheer volume of water I got in the hull in 48 hours can't be explained by rain.
