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?
