Bow ballast

My 9m RIB is pretty heavy and doesn't really NEED one but I do like going out in some very big waves(all ribs are good for). Having see the video of the lifeboat going tits up and watching a few others it seems RIBS are a bit light in the bow so I was thinking of fitting a bow ballast sytem.

Just wondering the best way to set this up - would it be possible to use a flexi tank in the bow - say 100 litres?

I have been looking at the Salmon powersports pickup scoops - they would be ideal but it's going to be difficult to run the large pipes through the hull - not many access points.

Maybe a hefty bilge pump would be better? Anyone uses flexi tanks for this?

The problem with a flexi tank would be splitting it - imagine filling it up at 60mph ......... the rule of thumb is to have at least as big breather if not double as the inlet. We use a big bilge pump to empty ours, but is has a well designed sump system to make it work.

You will need to empty and fill reasonably fast or it will be full when going downwind - not the best situation!

As far as comments like "RIBs are a bit light in the bow" - you should know by now (it must be on Google somewhere ) that not all RIBs are the same! Prop choice, rigging, driving techniques and 101 other factors all have a part to play!

Never heard of any racers that use them?

Another use if you're going to plan on doing very long passages is a forward fuel tank, but this would mean modifying the boat and fitting an extra forward tank and a tap system.
