And tomorrow's job is... this does look a bit scary...

With the boat upside down I probed every inch of the seams with a blunt scraper. It's weird how the glue is 90% OK but odd bits have let go for some reason. I've decided to re-do this 12" long repair up to the point where the original floor-tube bond is still perfect.... I'm sure it was watertight because the boat didn't leak rainwater but it didn't look as good as I wanted so near to the transom.

The image is just after I'd pulled it apart with the aid of a hot air gun.

I think it might actually be easier to do than the multitude of small patches where it was hard with so many different areas on the go at the same time to coordinate the three coats of glue in the active life of a mixed pot with these high temperatures.

Little bit too much bravado last night with the corner I'd opened up near the transom to re-glue.

It took about 2hrs to clean off all the old glue with the care that avoided going through the top surface of the adj existing fabric.

Then I struggled to find a way to pull it together that kept the seam anything like straight.

Eventually found that floor out, tubes inflated and roped in tight near the transom gave something to work to.

Left some of the scabby old glue on to glue the floor as it had been done before and to slightly the wrong line so the old glue acted as a guide that I had to come slightly inside. Where the surfaces were to be joined though every spot of old glue was removed.

Bought a new wallpaper roller with a slightly rubbery surface and this was just perfect for rolling the seam down.

Finally glued on the cleaned up existing reinforcing patch.

Final job is a real contrast to last night. Just a small wrinkle that probably wasn't there when new but nothing that will matter once the HP floor tightens it all up. Quite pleased to get this done as earlier today I did have a "what have I done moment" for pulling it apart.

And today's jobs are...

Now everything underneath is completed and the one actual leak on the tube sorted time to look inside.

There are 3 patches similar to the blue one on the inside of the floor... 2 well glued and just the corner lifting on the pictured one. I've cheated and used a bit of one part from a standard Chinese repair kit on this as it is not pressure related and I've already properly patched the damage on the outside.

The lower transom corner to floor area is the inside of the outside repair I made yesterday. Going to be much easier as the outer repair has pulled the floor into the right place already. Don't know if the image shows clearly but there is some strange black glue in this area from the previous repair.

One of the eight floor securing buckles is almost adrift and another a bit iffy so I'll do those. I think these are just to keep the floor in line when packed and during inflation as when hard it seems to tightly wedge under the tubes so perhaps not a crucial item... better done though.

And that's getting close to the end. Just the air floor to check now it's out as a last item.

One dilemma I'd appreciate comments on.

I mentioned in post 14 there were davit ring patches on the cone outsides but they were white hypalon fixed with scruffy glue. I uploaded an image of the one I'd removed and the original fabric behind had cleaned up perfectly.

The other one wasn't so straightforward... under the patch was a small square repair patch in white PVC. Totally sound but removing the glue residue from the davit patch has left discolouration and some places where my cleaning has taken the colour from the fabric.

For now as shown I've painted the white patch with some grey PVC flexy paint which looks a bit better from a few yards.

I've considered putting on a new large patch cut to fit to the rear of the rubbing strake, cut to the line of the welded seam under and cut along the top to curve down to almost the end of the cone. I have the fabric and glue so zero cost.

The ultimate solution is to buy a pair of black PVC 150mm round davit ring patches to cover this mess and have a matching one on the other side. Would look nice but about 50 for the ring patches.

Bit undecided.

All the buckles are now re-glued... as is that manky corner near the transom... looks so much better. This corner repair was the only place I've put any extra fabric so far. The buckle "backplate" was a bit torn so after gluing the existing bits back I cut a patch to go over it all and reinforce the buckle strap.

Very little work left now.

I remember reading ages ago about seats wearing the tubes of Aerotecs and mine shows signs of this as the two images show. I think it is the knurled nuts that do it.

No leaks but thought it wise to apply reinforcing patches.

That just left the air floor to wash and check over.

I'd not realised the floor panels themselves plus straps & tank attachment loops are all welded. The only glued seams are the "hinge" where the floor sections meet and the bridging piece.

Thankfully the floor passed a week long pressure test plus soap test. There were no seam issues... just the edge of the central seam towards the bow needed a few mm gluing together as per images.

I also checked for scuffing/wear at the corners/edges but there wasn't any.

So it's finished at last. I've cleaned it again today with some sib cleaner I'd had about for ages, touched up a few marks on the transom and seat with brush on satin black... and put it outside for all glued repairs to fully cure which I read takes about 7 days.

Then it's off to the Sound of Jura area (thereabouts) for a couple of weeks when the repairs will be well tested.

Nice job. Reminded again today in (slightly scary) gusty conditions off the Sussex coast just how capable the old Aerotec is. Make sure to try it in some lumpy water.
