I decided to remake all the engineroom hatches from scratch since the old ones were all too small once the carpet was removed. Three of my hatches were really big (the ones over each main engine and the one over the generator). As such, I decided to make them into multiple smaller hatches that were much easier to remove/store which has turned out to be really useful! I split each main engine hatch into three pieces and the generator hatch into two pieces.
The V-berth and aft staterooms are also both done, but they're a little messy right now and I don't think my wife would appreciate me posting those pics!

I didn't take many pics during the process but here's the final outcome.
