Wood Species for platform type bowsprit

I am replacing an Ash platform-type bowsprit on a CD30 that has rot around the through-deck bolts. The rot may have been partly caused by boltholes drilled for a windlass mounted on the bowsprit. All other exterior wood is teak. I could build a replacement in Ash but am considering something less prone to rot that would have a similar appearance to the teak. 8/4 Teak would be too expensive and difficult to source in the dimensions needed and I don't want to use a glue-up. A local service guy suggested ipe but I'm not sure that I can source 8/4 ipe locally in the required dimensions. However, iroko may be available, as would various species of "African mahogany." Anyone have experience with iroko for this sort of application or done a similar project?

I can get 8/4 Sapele here in Fairbanks, which is good. Wendy's resturaunts used Sapele print wall paper for about a decade which is maybe not so good. I am not sure where Sapele lands in the eco-friendly/ overlogging continuum. Sapele is not the easiest wood to work with hand tools.

Agree ash is not rot resistant. No experience with the other woods you mentioned. Good luck.

Iroko is a pretty common substitute for teak in British boats. I’ve used it for some smaller projects on my own boat to good effect. I would think it would be very suitable for a bowsprit. There are a few professionals here that may have more direct experience. Good luck with it.
