First Rib purchased, now the rebuild starts !!

Hi all, am new here but thought people might like to see the work I am doing to my rib.

Never owned a rib before, yesterday I purchased an 8m Ocean rib with a yamaha sterndrive as a project as I knew that the whole deck was completely soaked and rotten so needed replacing etc etc.

This morning the work started !! jockey seats removed, deck cut out (only the top laminate skin left !!) what is left of the plywood I have been scooping up with a dustpan !! just stopped for lunch and to watch Moto GP qualifying going to get the fuel tank out this afternoon and clean it all down so I can let it dry out. I am going to do the deck in sections, once this part is replaced (all composite and no wood at all this time !!) I will remove the console and do the front. In the meantime the tubes will get some much needed attention and all of the electrics replaced.

Thanks

Struggling with getting the fuel tank out at the moment, this is a prime candidate for NOT using open cell foam to fill in round a tank...... Total madness. I should say that I am not a novice boatbuilder it's just that this is my first rib 😀 just measured her and she is 8.5m not 8m so even more work to do so best crack on. Hopefully be able to post some pics later of the empty tank area !!

Tank removed

So I managed to get the tank drained and removed, fought me every step of the way !! pumped 70L of water from that compartment that the tank sat in and I would say that there was a good 20 to 30L of water as well still left in the foam on top of what I pumped out !!

Fairly happy with progress today considering how bad it was. Tomorrow I will get this area prepped, I want to put some extra bulkheads in as well so I have to make up some templates for those.

Hightower..... now you can see what the spade was ready for to remove the foam and also the fungus that was growing under there !!!

I'd already figured what the spade was for the foam, I like the Winsor brothers but they can be right cowboys at times

todays fun !!

So Today I got fed up of trying to work round the tubes so they came off !!

Cut the rest of the deck in the midships section that was left (both side parts) out.

Short lunch break to watch Moto GP

Then I thought I would see if there was any rot in the forward engine room bulkhead, all but one part was completely rotten as well !! so I ground all of that out ready for a new section of core material to be fitted.

After that I ground back all of the hull sides in this area where the deck bonds on so that is ready for the new sections of deck.

Templates made for the new bulkhead section so thats the job for tomorrow afternoon after our 95yr old grandfather gets presented a medal onboard the Victory in the morning

How did you get the tubes off in such a hurry? Last time I took tubes off it took me hours to get the transom area unpicked with a heat gun to avoid damaging anything

I have a tool that i use for splitting thick cable trunking that has a protected blade, i found that I could put this in the joining strip and just run it round without any danger of damaging the tubes. To be honest I haven't decided if I want to get a new set of tubes or not.

Ah ok so you cut the joining strip instead of pealing it off with the heat gun?
That would be quicker I guess
By the time you have done all the floors the boat will deserve a set of tubes especially if the old ones are less than perfect
Gonna be a new boat by the time your done

Yes, that is quicker

So this afternoon guess what............ yep more rot and frankly shoddy build quality. The actual hull laminate is very good and has quite heavy scantlings however everything else is poor at best, and there are some major design flaws with the fit-out work. (all of this I knew before I purchased the rib) I have no doubt at all by the time I have finished I will have the best Ocean rib out there

So to work, the one part of the bulkhead that I thought wasn't rotten turned out to be ..... well..... rotten !! once I braced the bottom of the hull I cut it out.

The new bulkhead that I am going to make tomorrow is considerably thicker than the original plywood so that does have some other implications. Not entirely sure of their exact name so I will call them the "side tube supports" well they are not long enough so first of all I need to extend them, only by 25mm but its still a job that needs doing.

Not sure how many people are interested in some GRP techniques or ideas so sorry if I am waffling on bit.

So Hot glue some 3mm MDF to create the temporary former and cover with vac bag high temp flashing tape, cut 4 x 25mm strips of 600g csm and 2 x 80mm strips of the same mat. Lay the 4 thinner strips as a "bandage" on a spare bit of cardboard and then peel off to apply to the job creating the "extension of the side tube supports. Then the same but with the 2 wider strips but use this to attach the pervious laminate to the original structure. Consolidate the whole laminate as one and leave to go off. In the morning I will remove the temporary mould, dress the other side with a thin laminate and trim the edge to suit. Then I can get on with making and fitting the new bulkhead

This is all very impressive stuff. Biffer may be gone but if you stick around, the whiff of resin will still pervade the forum.

What sort of nick is the Yamaha in? Must be getting on a bit!
