I got a couple days of boat work in this weekend.
After shop-vaccing the engine bay and cabin, I started ripping out all the carpet, but will need a second hand for finishing that job due to hardware requiring a backer screwdriver on deck.
Next, by hand/foot, started removing the rotten wood in the cabin. Bayliner used an isolated compartment for head drainage, which seems like a recipe for rot from day one. There were 10 gallons of water trapped, and Bayliner also neglected any kind of floor drain in the cabin coupled with using carpet.
Next, I reglazed the top cabin windows (tempered glass, not sure if they're original) with double-sided tape and Dow 795 silicon, as well as the starboard cabin windows (acrylic/plexiglass).
Instead of replacing the large window with the chip, I decided to sand that corner to hide the chip with a cordless grinder and a flap disc.

I made a mistake of using clear double-sided tape on these windows, so it doesn't look great to me.
A trick I found to quickly remove old double-sided tape was to very carefully use my cordless grinder with a worn flap disc; only go deep enough to just barely scratch the gelcoat without going outside of where your bedding will be.
The ~4" of wood around the fore-deck hatch were mostly mulch, so I'll replace that (not sure exactly how yet) soon after fabbing the new hatch.
Last thing, I thought it odd that the structure around the old large plexiglass window is cored with some kind of foam
