Transom door closure needed !!

[Blue_Runner]

I think you are out of luck B, sorry. No choice but to sell the boat. j/k

Worst case scenario you could get two matching closures and replace both. P/O replaced both my hatches (and round deck hatches) and below is the type of closures they have. Yours the same? Google search "Flush Slam Latch" , switch to image view and you'll see lots of different types to choose from.
