Just to respond/ add to two previous suggestions.
Chains- Navy anchor chains are flat rectangles/ lozenges, no twist. They also have a bar across the middle. I’ve messed up a few model foredecks with jewelry chain, would have been better off making the chain with the model look as good as possible.
Base- This is a critical step to a good display. For the amount of time and treasure that you plan to invest here, a few simple moves can greatly improve things.
You might be able to find a wood plaque at Michaels, but the ship is a little longish for that. Oak at Home Depot runs about $ 2.00/ ft. for 1’ x 4".
There’s plenty that’s been written on this, the basics are to plan to mount the ship on a couple of short pedestals on your base. Pick where you want them; two will do and keep them in the center third or so of the length of the ship where the keel runs level.
Before you close up the hull by gluing the deck down, locate and drill holes where the pedestals will go. Put something in each location into which you can insert a bolt or a screw from underneath. A nut, glued in. Or a small block of wood with a pilot hole in it.
For pedestals, the sky is the limit. The simplest might be a short piece of tubing, either brass, or painted. It can get complicated from there, largely depending on your access to basic machine tools. I use little lamp part nipples. They’re about 1/2" diameter and come in lengths from 1/2" to an 1" or so. Easy to find at Ace.
Drill two holes in your base, where your screws or bolts will stick up from underneath. Countersink on the underside so the base sits flat.
Put this all together and fiddle it so the ship sits level, side to side.
I like to build on a base, and I have some building bases made out of pine that I don’t mind getting paint, tape and doing math on. Towards the latter parts, I switch to a finished base and keep it clean.
Either Ed, Bill, Tracy or one of the other masters here showed a base for building that I think really works. It is longer and wider than the ship, and has a second piece turned up at one end. That’s not for standing the ship up, but you can lay it on it’s side without busting off stuff.



I hope that helps,
