I WOOD recommend SS railings. I have wood and they are a lot of work to keep varnished. Actually they are just part of it but add to the job.
However if you want wood decide if you want the typical oval type railings or would be happy with flat, rectangular lumber type rails. I have the latter and they look darn good when in good shape. I don't miss, never had, the oval type.
If the flat lumber will be acceptable then many shops can fabricate them. Just depends upon how elaborate you want them. Maybe you could even do your own.
Mine do follow the bow curve right to the pointy end and there are several joints which I don't think I would tackle as the fit is perfect. [t'was a Good carpenter] . The varnish also keeps those joint tight.
Many trawlers joined the wood to the SS bow rail at some point so a landing pad could be welded to your existing bow rail. WOuld simplify the process as cutting those curves would use a lot of wood and be expensive, especially in oval.
There are boat woodworkers in many areas. You are near some or should be. Also Anacortes and Port Townsend. There WAS a G.B. specialty repair yard near you, don't know the name. Ask around and maybe they could help/guide you for both types of rails and the stanchion fabricators as they would have dealt with oval for sure and I'll bet flat.
