The tubes on my 6.5 have started letting in sea water both at rest and also underway!!! The water is coming in between the tubes and the hull!!!
YES I did have a bit of a moment when I noticed it when towing another RIB the other day. It is only happening on one side though. Enough water comes in to have to operate the bilge pump about once every 3-4 minutes.
The local authority RIB has had the same problem and it is the same 6.5 Ribcraft!!!
Has anyone else had any problems with Ribcraft tubes coming away from the Hull?
Before anyone asks, it has got nothing to do with the Fire Rescue in Torbay yesterday!!!
Yes, our bow tube came away after stuffing it in to a wave! Easily repaired and been very solid since. Have no fear, they are one of the best ribs you can get.
Yours was finished about 3 weeks before mine (if I remember right!!) - and I've had no problems with the tube/hull attachment - so you might just be unlucky.
I have had one of the triangular hypalon patches on the rear underside (the 'kick' pad?) start to come away along one edge - Jason and Mark offered to repair it or send me the kit to do it myself - which is what I've done and it all seems to be OK!!
Just my luck that Ribcraft are on 2 weeks shutdown.
I have already spoken to Mark a few days ago and I agreed to live with it until they are back.
It have a feeling that the problem is at the back which is forcing the water forward when at speed causing it to come out further forward. The reason for this is even if we are trimmed right up a bit too much with most of the port tube out the water there is still water coming in forward which makes me think the "hole" is at the back near the transom.
Anyway, I will just keep pumping it out until Ribcraft come down to fix it!!
and put a chunky deposit down
