If i remember correctly, the original had problems with the original hull (I forget what), it went back under warranty, new hull was built and engine outdrive and tubes switched ovet to new hull. Maybe shortcuts were taken as it was a non paying job.
Maybe I am putting 2 & 2 together and getting 5, it just seems to fit as a reason.

Neil, its a possibility but if that is the case then they cut corners with a hull that was supposed to be replacing one that already had issues ? Someone I know works for one of the largest naval architect firms in the world that specialise in Military and Commercial craft with his speciality being high speed composite (including carbon) vessels. He came to see me on Saturday and once he had stopped doing this we discussed various things about the hull but the main thing he found unbelievable is the fact that there were NO watertight bulkheads on the port or starboard sides bow to stern. This is something that I have addressed already with the new bulkheads but will be fitting more as the build progresses.

Anyway i think from the start of this thread we can all see how shocking this particular rib was when I got it, whilst I wouldn't want it to be the case for other people to have problems with their boats as well I am not worried about any other boats (got enough on my plate with this one and everything else I have to do in a normal day !!! but as I have said before I was aware that it will be a total rebuild).

I have however managed to find the only bit of plywood on the boat that wasn't rotten or even wet, it was used to try and strengthen the engine room cover and this didn't work (never would have worked) so the moulding was all distorted. I promptly turned it into "bin size" bits and have re-designed in my head how I am going to do the whole aft section of the boat

I think it was gelcoat issues on the original, maybe talk to Gareth at Drivers about it if u want the proper story less second hand than my memory.

Clearly I'm no naval architect...

Do you need watertight bulkheads? I thought the toobs would keep it buoyant? And the toobs have baffles which are in effect bulk heads?

Likewise the cardboard tubes with CSM and resin over... ...boat lasted this long and the curve shape gives it some structural strength. Not saying its perfect but maybe it was enough for the job...?

Hehe yes, eco friendly is the key. I burn all of my mat tubes and pallets on my log burner they kick out a huge amount of heat !! 😀 well you can use anything for a former, but you could use something that didn't absorb water !! Ethafoam would have added about 30 to the cost of construction, was available when the hull was built, had been for years and commonly used as stringer formers in hulls.

It's not just for the watertight ability of the bulkhead you also want to have some structure for the hull and deck supports and it might just be me but I would also like to think that my hull had some sort of ability to stay afloat if swamped and the tubes were damaged. Once I have finished I will also be able to calculate the built in buoyancy of the core material I use and how much that can support on it's own.

Love this build thread !
As Shiny said, i suppose the cardboard was "enough for the job " at the time, and also Maybe to help with future business it is best for manufacturers to build boats that WONT last too long so they can sell new ones in future? Makes sense, but I can't understand why they wouldn't add in at least a few water tight bulkheads into the hull!?? Scary!

So the big "tear down" continues, the rats nest of wiring has now all gone in the bin and the console is back to pretty much a bare moulding ready to cut off once I have finished the fuel tank and got that new section of deck fitted. Then I will get on with a plug and mould for my own design of console

Wow that IS another level!...Look forward to seeing the design /specs ect.
It certainly looks like a quality job so far!

New console.
Rewire.
New deck.
New under deck structure.
New tubes.
The hassle of ripping it all out in the first place.

At what point does it make more sense to start from scratch?
