Hole in my rib?

Hi all, just a quick one, I'm colin and I'm new to boating, I have just got my first boat, it's an older rib think its early 90's, it has a Yamaha 30ae motor, I just don't no what I'm meant to do about a hole at the back of the boat right at the bottom of the hull. It has a plate on the outside but this too has holes in it, I have read something about a flooding hull, is this the case with my boat. It just don't feel right having a hole that you can see through in a boat? I have uploaded a pic to show the outside of the hole the pic is not my boat but is the same boat Thanks in advance colin

I think that fitting may have had a non-return flap incorporated. (It's a long time since a friend of mine had a Flatacraft!)

Does the fitting come apart?

You might need to obtain a bung to fit from the inside.

Rubber cork from a home brew supplies shop for example - Scorpion use demijohn corks inside their fittings!

Yes it dose appear to have a piece of material in it, it looks like it could be a flap of some kind as its only secured at the top, can this just be replaced? Thanks for your reply

Sounds like it.

If the fitting comes apart there's no reason why the flap can't be replaced. Will need to find a local rubber supplier.

Will still need a bung / plug inside though.

The hull does look hollow it's all open next to the hole, I have read that it has a flooding hull and it empties when planing and floods when going slow??? But I'm still unsure weather in needs a bung or not, it looks like it would be difficult to put a bung in cause of the shape of the opening from the in side of the boat, thanks for your replays by the way.
Kind Regards colin

If it's a flooding hull, I think it should have one or more air inlets near the bow. These allow air in when rising on the plane and thus allow the water to rush out the stern hole quickly. That's how it works on Avons anyway. If you have these, you'll need to block them too.

That thing on "your" transom doesn't look big enough to be a flooding hull opening IMO. Does it open into a deck well or under the deck, i.e. you can't see it from inside the boat?

Yes you can see it from the inside of the boat, but it does open to a place between the floor and the hull, you can get you hand between the the floor and the hull, I will add some pic of both inside and outside, at some point today. And thanks again

Ah, a Force 4, as others on here will know they make me all gooey inside

So, the hole/ali box/flap was Flatacraft's attempt at a self bailer.
they work great until the smallest bit of debris gets in there, then it will leak when you stop.
Replace the flap with a new bit of Neoprene, clean it all out well, and it will be good.

No Force 4 came with a flooding hull, I can say that 99.9% for sure.
EXCEPT - When the flap in the self bailer leaks

There are some interesting Force 4 images in my gallery.
