How to block water???

We have a very nice aluminum RIB with a double floor and a locker in the bow. I have the fuel tank in the locker (among other things) with the fuel hose running aft to the ON under the sole ... which is terrific to have the sole uncluttered. The problem with this is when water from rain of several days fills the RIB... it can be even 4 or 5 inches deep... a lot to de water. But worst of all the locker floods too and becomes a very wet locker!

I want to create a dam by place a channel scribed to the V or the hull where the after side of the locker is. It has an opening to pass the hose under the sole obviously. The hose would then go up over the dam which would be 5 " tall and made from a GRP channel.

My question is... how should I attached this channel to provide a water barrier? My first thought was bedding its edges in silicone. Then maybe epoxy... What about butyl rubber? I can "build up" silicone... as appearance is not an issue.. and it's probably easier to work with than epoxy. Butyl may not adhere.


pay attention... someone's life depends on it
