FRIB filling up with with water

[Dublinpup3]

Hello everyone,

My Frib 375 fills up with water within an hour from being pumped out.
My first thought was the drain plug, however I don’t see anything coming in from there so now I’m thinking it’s the fiberglass, seems, or that rubber strip on the bottom.
Any ideas on how to remedy this problem?

Is it coming in via the bolt holes? I recall some other people having problems with this.

@Martin might be able to help.

Just a thought - Make sure that the washer on the rubber joining blocks (?name of part!)is behind the wing nut and not up against the hull at the join. I once installed one back to front when in a hurry and could not believe how much water got in.

You guys are awesome I think that may be the problem at the bolt holes. I hadn’t thought of that but it makes sense and I know I’m missing a wingnut and tried to just put a random bolt on. I Was thinking of the bolt holes more as a structural piece meant for collapse prevention and not about taking in water.
Well that may have made my winter project easier

I also recall one having a damaged bolt hole but hopefully its just as above...

Hi
I have been assembling my F-Rib as shown below. Is it correct?
Bolt + Washer + Rubber Bushing Hull Hull Rubber Bushing + Washer + Wing Nut

The Rubber Bushing seal to the hull on both sides while the Washers distribute the force provided by the Bolt and lock washer.

That's spot on.
