How to fibreglass repair a plywood tender

[conks01]

Hi,

I'm a complete novice when it comes to this so all advice is gladly welcomed.

Mice chewed through my 18 month Seago SL230 inflatable and it is damaged beyond repair.

I've been offered a plywood based tender from a member at the club (for free) albeit it needs work. Some of the hull surface area is 'bubbled' so I'm told it will require patching with fibreglass.

Can anyone recommend how to go about this, what is required and where to buy etc.

I'll try and grab a few photos if I manage to get to the club later today.

Thanks.

What do you mean by "bubbled"? De-laminated?
What did the people who told you it would need" patching with fibreglass" mean?

Much more info and some photos needed I think before anyone can offer any advice.

An old fibreglass dinghy might be easier to repair than a plywood one in bad condition.

I fixed up a ply mirror dingy by scarfing in ply panels of the same thickness. I used thickened epoxy for glue the scarf's and then reglued the tape also by using epoxy on the woven tape.

I sanded the scarfs with a small angle grinder with a sanding pad.

Vic,

Sorry, my mistake. I've discovered today that it's actually GRP and not ply based.

I've uploaded the pics - see at the top of post/thread.

It needs TLC. There's a bubbled patch so not sure what to do with that? I was wondering whether I simply need to rub down and paint with epoxy filler / paint ?

Thanks.

I think it's an old tender, so it just has to do the job, not worried about pretty?
I would sand that down. I'd use a sanding disc or flap disc on an angle grinder.
Then decide if it needs more reinforcement.
If so, sand the inside and add a couple of layers of mat and polyester resin.

Ideally, finish with flowcoat/top coat, or maybe deck paint inside.
Consider adding a strip of wood, plastic or metal along the keel to take the wear?

Thanks. That's what I was thinking. Re the bubbled patch, see pic at top of this post, do I need to do anything with this?

Is this what you mean by "bubbled patch"

If so just what is that all about.

I think I'd clean that off to original and then make a proper glassfibre repair if its patching a hole

Yes.

I believe that it has been poorly patch repaired albeit the patch has bubbled.

I didn't know if it could remain in-situ and I could seal over? Failing this and as you suggest would I sand off and then reglass the area or if it's not leaking leave it and paint over.

Well if it were me I would simply start using the dinghy. Scruffy is good when it comes to deterring thieves. You will soon see if it takes water and needs repairing. If so use epoxy and a bit of glass to patch it and if you want paint over t with 2 pack paint or indeed anything. ol'will
