I am going to look at a dead Centaur with a squidgy foredeck that it acquired following a front end ding

the push pit is also bent and the ding let the moisture in

what are the consequences of a squidgy fore-deck

enlightenment sought

I guess that the balsa filling is stuffed. You can fix it or ignore it, but fixing it requires cutting holes in the deck, routing out all the rotten balsa & then backfilling with something (resin & a lightweight filler?) to stiffen it up. For the sake of a couple of months utter thrashing, I wouldn't really expect it to fail.

can I re-enforce it with wooden battens above and below and bolted together?

How about a backing of ply underneath and bolted through if your not too worried about looks. Maybe easier and quicker than battens?

Where is this in relation to forestay fitting? I can't remember how that is attached on the Centaur.
 
I know this is a bit off the wall but .... Some years ago I owned a touring caravan which suffered from a sqidgy floor. The dealer wanted a serious amount of money to remove the whole body and replace the floor which was ply and had delaminated. Then a man who serviced caravans suggested drilling some holes in the outer skin and injecting in some expanding foam. Worked a treat an cost about a fiver !!!

I guess you mean pulpit (bow) not pushpit, or is that bent too?

Personally, I would have alarm bells ringing at this point. It must have been a colossal "ding" to have made the foredeck squishy (a short, stout thing on a Centaur) and I would be far more concerned over the structural integrity of the topsides and the bow fitting.

The Centaur is generally built like a brick ****house, it had big box section gunwales and it just doesn't strike me as the kind of boat that gets a squishy foredeck through a "ding". Unless it's very localised, or had something big and heavy dropped on it, I would say there are bigger issues here.

Difficult to see without pics etc...but be wary!
 
My W21 did not have a cored forehead I am pretty sure. I don't know where I got the idea, but I have always assumed that Centaurs did not either. Stand to be corrected (and probably will be!). Always associated balsa cores with lighter, cheaper, builds then Loyds regulated Westerlies.

me too

I hope we shall soon learn more when an expert appears

I have emailed my centaur anatomist but he is busy

I did mean pulpit....

and all boats at this price level will have problems

some are worse than others

Dylan. It might depend on the age of the Centaur, I have a later one (1978/9) and it does not have balsa/core forward of the hatch. I think there may be some a lot further back behind the mast, around the coach roof. Hope this one is a go-er for you.
 
That's good. It is said that the later Centaurs had a lot of the early problems ironed out, better keel fittings and the leak over the windows due to the shroud/ chain plates issue (extent of my knowledge but I'm sure you've read more than me by now). Mine is a B lay out too. If you need to remove the headlining irrespective of what you do next use the best ventilation mask you can, I used the method recommended by Hawke House (angle grinder and special brillo pad type disc)and despite being as careful as I could had a persistent cough for weeks after. That was the dust and nothing to do with glue....
 
I had a Jag25 years ago which had a creaking foredeck due to a knackered balsa core. the surveyor said to drill a series of holes in it (about 12 inches apart), and then use a big syringe to squirt resin into each hole until it comes out of the ones next door.

I guess you'll need warm, thin resin with a slow hardener though (I wouldn't know because I never bothered with it).
 
Dylan has a handy epoxy source possibly?
Be wise that wet is wet and epoxy doesn't stick until you dry it out ( and remove rotten debris and salt)

Now, in true ''lets not muck about 'ere '' fashion, I offer you the two sheets of shuttering ply, a handsaw and a 12pack of Liquid Nails from Screwfix ..20minutes ( plus painting) ...?

In true workboat fashion.

The pullpit will unmangle with some 2x4s tied on and used as levers, judiciously..

Actually your batten-it-top-and-bottom is fine and fit for purpose..
