Transom patch

[mvs788]

Thinking of replacing this section of transom with blue water Coosa board
The roughly an inch and a half thick by 2‘ x 4‘
Epoxied and glassed in.

Thinking of replacing this section of transom ...

Just the center of a larger full width transom?

 

[Scott Danforth]

replacing just the center and having two joints is like trying to replace a section of a full-span bridge with toothpicks

Yes

What if I went all the way across, from gunnel to gunnel, Without going below the deck into the bilge area

gunwale to gunwale, keel to cap

If you're going for a rowboat your patch might work for a time.

Have you done any investigation below deck for rot? Boats rot from the bottom up so you’re not really doing yourself any favors by just replacing small pieces. It’ll be weak structurally.

So I’m guess I’m looking at tearing out the entire transom well, to replace the whole transom in one piece.

One of the braces that come up from the bottom of the boat through the transom well is rotted. So I guess I’m looking at tearing out the entire transom well, replacing the transom in one piece, and rebuilding two brand new braces.

I worked on the Throgs neck bridge for three years, it’s more like Band-Aids! That we put on bridges.

You're probably looking at a full gut and restore. Stringers, floor, and transom. This isn't a piecemeal type thing.

 

[flashback]

Yep keep digging, if anything structural has rot it needs to be replaced in it's entirety not patched and most of a boat is structural.. good luck with your project

If you got all the rotten wood out, you could just replace what you cut, covering the joints with several layers of Glass, each new layer a couple of inches larger than the last, and a couple across the entire Transom and overlapping on the Sides. The repair is strong till the glass ends, which is why I tend to go a bit overkill. Too often I have seen a Structural Repair on Glass Hulls, where the new Mat, not even cloth or Roving, forms what is practically a Butt Joint, with an overlap of 3/4" with the old glass

OK so, I just realized one of the stiffeners that come up to brace the transom is comepletely rotted,hollow inside.

you will most likely find the stringers are also gone and the flotation foam is waterlogged

I’m gonna open up the old floor today, The previous on it put plywood on top of the rotted floor. It’s a 1986chawk, not sure if they used flotation foam

A deck over is never a good sign

Guaranteed it had foam when it left factory, w a deck over expect foam to be a foul waterlogged mess

the deck-over is a sign of rotten transom, stringers, etc.

the deck is always the last thing to rot

welcome to the full gut-n-restore crowd.
