Sweet! Im glad, so how much glass resin should Ineed for a 4x3 section of new ply?

You are indeed Lucky and should takes EZ's advice and buy a Powerball ticket...

As far as how much resin you'll need, depends on how you are going to do the repair...if you do it the way that I have seen recommended here on the forum...

Make sure the wood is as dry as possible and of the right kind...
Soak the wood with resin first...
Apply a layer of CSM to the underside...
Then install using your choice of thickened resin over the tops of the stringers and held down with weights, or stainless steel screws buried in the plywood but first coated in 5200, or 3M 5200 as a sealant and adhesive...again your choice, any, a combination or all of the above...
Then apply a layer of CSM and/or 1708 biaxial...or a variation of those, as needed to level with the original deck...

You might need about a Gallon or so of resin...

It seems like there was never any CSM on the underside of the floor...??? Why would this be like that? Cheaply manufactured? Or has it already been worked on? (though i doubt it)
honestly, i wanna do it right, but would it do much good to glass the underside of the whole rest of the floor isnt?

the underside was still wet feeling meaning it cant be sealed with any kind of glass correct?

Also by "use a thick resin and hold down with weights" do you mean as an adhesive for the plywood to the stringers?
Is this method is to avoid screw holes?
A polyester resin should work ok for this correct?

should the CSM or biaxial run past the repaired section and part way up the wall?
Or just on the repaired spot?

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

there is that board (approx. 2''x10'') that runs width ways across the center of the boat.
I mentioned before on here, it has two drain holes at deck level (which is the center of this board)
and the wood is soft about 2'' around this hole.

Is it possble/ok to "paint" on some resin to this area overtop the soft area?
the water is seeping in from the insde of the wood from the holes being drilled and not sealed %100

I think that's pretty common on "consumer grade" boats. This picture is from my 93 Bayliner 1952 inside the bilge locker (it's not quite big enough to call a ski locker). It looks like they just stuck a spray gun inside the locker and did a general spray of paint, but there's no CSM or any real effort to get full coverage. Kind of shows why leaving these boats outside and uncovered all year isn't a good idea.

This is so stupid lol. Ya thats pretty much what mine looks like, i may even say worse! it barely looks like they tried to treat the underside.

So what should i do? Half a** it because they did or have one little section done right thats gonna outlast the rest?
At the very least could i just coat the underside of new wood patch with resin and maybe reach under the remaining
floor as far as i can reach from my patch area.

It seems very dumb to make a "boat" not even close to waterproof.
I wish they made all composite material on the stringers and transom so they never rot.
but then of course they wouldnt sell as many boats and become even more crazy rich. haha:lol:

I wouldn't go hog wild on it. No offense but this was the bottom of the line boat from the bottom of the line boat brand at the time so yeah, it's ain't built real well.

no offense taken...lol
by not going "hog wild", do you mean i should just glass the top and leave the bottom alone?

home depot has a fiberglass mat about 8 sq ft. $7, and gal of poly resin $40 should i just go with that and cover the new piece then
recarpet and re vinyl and its good to go??

I'm back.. I was out of town for my sister's wedding... Here is my .02

the reason the transom wasn't the same color is because it is ply and the stringer is most likely solid.

The underside of the existing floor isn't glassed so you will be ripping the whole floor up before your new patch fails soooo.... get a gallon of exterior house paint and primer in one... paint several coats on the underside of your new patch... get marinetex putty and fill all of your drill holes and any existing screw holes.... cut a strip of ply 10" wide the width of the span between the stringers and paint it on both sides and the edges... sealing screws with 3m 5200 screw the existing floor to the top of it so that you have a 5" ledge in the front... do the same in the back... mark the locations of the stringers on the existing floor near the patch hole... lay the nicely fitted patch in place and again sealing w 5200 screw it to the 5" strips and the stringers.... get EPOXY resin not vinylester or polyester and whatever glass product the glass guys here recommend and coat the top..... if any cracks remain from poor fitting of the patch they can be filled now....

Epoxy tho more expensive sticks to anything (within reason) and the other resins can be difficult to get good adhesion to existing surfaces.

The paint on the other side will seal it up far better than the old wood everywhere else and you'll be GTG.

AWESOME!! your the best smokeonthewater

That sounds great, one question though, where the "front" of my hole is there is a bulkhead...
So how could i make the ledge that your describing?

kinda stumped....:facepalm:

p.s do i have to use a fiberglass mat of some sort with the epoxy resin?

 

[Lukelona]

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

where is the best/cheapest place to get epoxy resin?
i dont belive home depot or lowes has it right?
west marine maybe?
kinda looking for somewhere local. but not overpriced

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

since your in virginia, hit up jamestown distributors.

Marine Epoxy Resin

if you were closer to florida, hit up US composites
U.S. Composites, Inc. - Fiberglass , Epoxy , Composites, Carbon Fiber

shipping for small amounts would be more than the actual resin and mat.

also, mat for polyester is different than mat for epoxy.

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

did you buy that lottery ticket yet. you are the only person I know where the soft floor was not due to rotten stringers and transom.

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

A couple options... IMHO the best option is to extend the hole forward of the bulkhead... the other would be to screw a 2x4 to the bulkhead but I think that would be very likely to loosen up and allow water intrusion.
yes use glass cloth on top of the floor... doesn't have to be anything special just there to add thickness and abrasion resistance...

Another thought... 86 the new carpet and coat the floor w a non skid floor paint... If you desire carpet at that point you can cut to fit and have the edges bound... then install snaps... You then have the option to install and remove as needed to fit the day's planned activities PLUS you won't destroy the carpet if you need to do another floor repair.

lol No i havent! im not counting my chickens before they hatch lol
I will buy one after i load it up on the trailer after taking it out all day. haha

This all heppened because of a stupid design of bayliner. the deck had two pieces of ply meeting on the inside of the stringer!!
So where they met together eventually got weak and the corner of one piece of ply would sink down making it feel soft.
And the fiberglass was worn off the deck in the high traffic areas. IMO making it weak and open to failure.

"A couple options... IMHO the best option is to extend the hole forward of the bulkhead... the other would be to screw a 2x4 to the bulkhead but I think that would be very likely to loosen up and allow water intrusion."

How would you extend the hole forward.? you mean like a horizontal pice of approx. 1" tube throught hole and sealed around
the edges so deck water flows through the tube instead?

And by using a 2x4, you mean put it against the bulkhead as a "sister" board to prolong its life/strengthen it?

 

[smokeonthewater]

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

The hole I was referring to is the one you cut in the floor

The 2x4 would be the other option to make a ledge the floor could sit on. But NOT the choice I would make.

The 2x4 idea is what i had in mind, its the only way i can see it working.

Im not sure what you mean by "extend the hole forward of the bulkhead"
this bulkead doesnt have deck laying on top of it, it is what makes up the seat base that goes all the way across the boat.
so its kinda a "wall" right there.
So wouldnt the 2x4 ledge be the only option?

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

how was it attached before? Tabbed with glass? that would prolly be the best way to do it

 

[Lukelona]

Re: GENERAL CURIOUSITY...Would a boat with a soft or rotten floor have any chance sin

it wasnt attatched to the bulkhead with any supports . it is just CSM running few inches up the seat base.
If this is what you meant by "tabbed with glass."

I really think all these designs suck and now i relize why there is so much negitivity against bayiner crappys.
I just want to get it decent and safe! Looking good and running right...if i get 1 or 2 seasons outta it ill be happy.
Id be extra happy if it lasted good and i could sell it to get some money toward my next nightmare. :laugh:
