Fun after my retube

well this is the 4th trip out on my Rib after its retube and mn is it going well.
BUT... when recovering it last time out I noticed it seemed little "heavy" when revocering it.
I put it down to the steep slipway and thought nothing of it.
Sunday had a good blast out and it was running flawlessly.
Recovered and again hmm I dont remember it being this much effort to drag it back onto the trailer.

Sooo. today while cleaning it noticed while sitting in on the deck noticed a sloshing noise. hmm
Fuel, nope.
Oil in oil tank..nope
Oh dear.... Water in the Hull space..
Checked the bolts that go through the hull and one was not even close to be tight!!!

AND NO SEALANT on any of them!

I know the A frame was taken off when it was retubed but leaving one bolt loose so water can get in is a basic error.

The problem is my hull is , or was unitll I drilled into it to put a 6mm tube in to see what was going on, seled.

So Experts how do I get all the water out?
Have shyponed alot out.


I expect water may have been getting in for a long time. how much damage will it do to the inner hull?

Should I be very concerned??

HELP!

Is there no drain for the inner hull space?

At least over here in the States most trailered boats have a drain for otherwise "sealed" hulls since they inevitably get water inside at times.

You might wish to install a drain with plug in the lower portion of the transom. You need to get the water out as GRP will absorb water getting heavier and weaker too. And most certainly you wouldn't want the water to freeze inside either.

Well I noticed it today so I have no Idea how long the waters been in there.
The boat has a sump at the tansom so there is gap between the tansom and the actual hull void.
If that makes sense
So I would hve to dill through the transom and across the sump to get to the hull voild.
Unless somone local has a 90 degree drill

Are you sure the floor of the sump is bonded to the inner portion of the hull? The Avon hulls I have seen with that feature have a gap in between (and an inner hull drain too). We don't have Ribtec's over here so I am not familar with your hull.

Jezza my Ribtec 535 (and 585) both had drain points on the bottom of the V of the hull, there was a gap between the bottom of the sump and the hull which the water would pass between easily. Have a look at the V in front of the outboard leg, any sign of a filled hole/removed bung? Ribshop sell the actual Ribtec bung and fitting.

Hi Kernow. I wish there was.
No the transom is flat no bungs or holes.
The sump has my transducer in it so I know its solid to the outer hull from the sump.
My Ribtec is a very very early one.
on of the first ones.
bought it from the boat show in 1991. so wayyyy old. they did some significant changes to the hull after that.

I think the words I am looking for are ARSE and BUGGER ;-)

Ah, pity My 535 was a 96 and the 585 is a 95 so fairly early ones too. The 535 hull never took in a drop of water but the 585 let water in via the under deck trunking. May be worth asking Biffer, font of knowledge on Ribtec's

maybe but its also not the worst fault we've seen mentioned by a supplier on here even in the past few months! I guess its possible it was tight and worked loose.

it says a lot for the original build that it lasted 20 years before any water got in there. Most boats have a drain.

I would add a drain. If the sump is too small for a drill then perhaps a dremel?

Many boats have water slopping about the bilges. Its not ideal but if you are talking about a few weeks or months of wetness it is not going to have done any damage. Fit the drain and you will be right as rain (assuming of course the underside of your deck was sealed before fitting).

Thanks Polwart.
Not sure if the under side of the deck is sealed/glassed
from what came out then no. it may not be. But its not bouncy or spongy in any way.
nice clear noise when you tap it.

I guess worst case I would have to chop out the whole floor and re glass a new marine ply floor.
Re-glass in.... Ohhh sounds like a big job.

drilling in it seemed quite wet and not too solid.

Thinking of putting a hatch in or taking the time to chop out a big enough section to see exctly whats going on.

But as its going well seems solid and sturdy I am hesitant to start making big holes.
