Thanks for all your help and advice gentlemen, most useful in planning what to do.
I have several options and I'm now trying to sort out the best way forward!
Cheers,
Mike.

Hi Rob.
It was your boat - but I doubt it is alone with the feature. As you say, it's a benefit for you as you're aware of the issue and were able to drain the water! Your Navigator does great service braving the elements of the Thames Estuary - a credit to the type!!
Cheers Rob.

Hello Simon K
I think it may be my boat you were referring to when you said "I've seen a problem in the past with a nav where water under the cockpit could leak into the cabin due to some poor laminate at the "joint" between the cockpit and the cabin - the water came out adjacent the galley unit - but there was a lot of water under the cockpit!"
When you saw my cabin floor it was about half an inch deep with water on the floor.
I never said and should have done before but after I removed my table leg which was so badly stuck in the socket I was worried about breaking the base removing it.
After I removed it, I noticed it was full right up with water.
With a syphon pump (about £7.00 from Aldi) powered by 2 rechargeable "D" batteries, I immediately filled up three one gallon buckets. I then went down river for about 10 miles. In the morning I filled up another couple of buckets. I then went a further 15 miles of tidal water. On arrival at the mooring, I seem to remember I had at least a bucket of water to syphon out.
Since then all I have had to syphon out is the odd two pints here and there.
I am not sure if it was due to poor laminate at the "joint" between the cockpit and the cabin but it looks that way. In some ways this is an advantage to me in that the cabin and cockpit drainage are connected and I can syphon it out by the socket where the table leg goes.
Hope this helps.
Rob

Hi Mike,
Have you thought about reverse fixing the seat to the floor. A common practice on many boats. The Idea is to decide where you want to put the seat base and then get a piece of very heavy marine ply 50 mm thick and make this over size of the seat base. Then drill and glass in the fixing bolts from the underside so the bolts protrude through the ply base. When this is cured glue and glass in the base to the cabin floor in position so the bolts protrude upwards. When all is cured and dry fair in the base to make a neat job. You then have a reinforced floor with seat fixings. The beauty of this is that you are not penetrating the cabin floor so no damage is done and no holes to worry about leaks etc.

Thanks for all that Simon. There does not seem to be too much water coming out of the hole, so it could just be back flow from the rear sump.
I seem to have stopped most of the incoming rain water by retrimming the boat with ballast. My main concern was the floor and void thickness.
Thanks again for taking to trouble to advise me.
Cheers,
Mike

Hi Mike.
Sorry - I've been out of comms for a while.
Simon P knows the construction best - I have a later Nav with the removable centre panel - this I've had to replace with 12mm (nice Teak and Holly Effect Lamiante Marine Ply. The gap below the floor is still about 4inches...
I've seen a problem in the past with a nav where water under the cockpit could leak into the cabin due to some poor laminate at the "joint" between the cockpit and the cabin - the water came out adjacent the galley unit - but there was a lot of water under the cockpit!
My Navigator has some water in there when I bought her (simply the previous owner not keeping the drain plugs in under the engine well and letting the rain poor in!!!). If you have a water leak in the galley from a water bottle - that could seep into the area under the cockpit and cabin - perhaps...depending on the moulding quality there.
The only other leaks could be from Hull penetrations - are there any fittings screwed into the transom that are badly sealed?? A speed or depth transducer is a common fault - water could leak through into the areas under the aft jump seats.
I fitted two fibreglass seat boxes within the cockpit - and accidently drilled through the hull bottom - just.... under where the seats would be, these very little clearance between the deck and the hull - so be careful. (I ground out and repaird my error with West Epoxy - better than new).
Best Regards
Simon.

Hi again Mike,
Communications up the spout at the moment, including my HOC one, but still trying to sort this end. In the mean time, I had a text from Simon Kidd last night about various stuff, but he did say he would contact you, so at least got that far....
Hopefully speak soon,
Marie

Thanks Marie and Simon.
The water is not really a problem as there is not much of it, just wondered if it could get in elsewhere!
It sounds as if the floor is pretty strong which is good.

Hi Mike,
Having built a fair few of these during my time at Hardy Marine. The cockpit floor is about 1 inch thick and the void space between the under side of the floor to the hull is about four inches at the aft side and increasing to six inches at the cabin entrance. The drains at the aft end need removing and fresh sealant putting round them before refitting them. If your boat was laying around for a long while and the well filled with water and back flowed under the floor. The best way to get rid of the water was to lift the bow up when the boat is out f the water and then pump out the well when the water comes out of the drains. The other way was to fit an inspection hatch in the floor and empty the void space with a manual bilge pump.
Regards
Simon Papendick

Ahoy Mike,
Just sent you a long email with my own experiences re my Pilot, but you need to talk to Simon Kidd about this and what he has done with his own Navigator. Speak soon.
All the best and also Happy Easter to you as well.

I wonder if someone can answer the following.
I have an old Navi (number 777) and would like to know if possible what thickness the rear floor is above the void, and how deep is the void under it!
Also, there is a hole in to/out off the void in the rear well under the OB recess.
Water often comes out of this hole, so, where else can water get IN to the void?
The main reason for asking these questions is that I would like to possibly fix a seat to the floor!
Obviously I could not use bolts, so would have to use screws - and would not like to cause any damage!
Thanks in great anticipation!
Happy Easter to everyone, but it does not look much like boating weather!
