non teak rub rails and toe boards?
While the heart wood of properly air dried black locust is about as rot resistant as a wood can be, the sap wood is a highly unstable, more prone to checking and rot. It is hard to find clear straight lengths of black locust and while there are other types of Locust these are totally unsuited for marine applications.
Both the African mahogany and fir are a little soft for rub rails and these materials need to be kept sealed to prevent rot.
We have been using a lot of Ipe for decking in our area. It appears to have many of the favorable characteristics of Teak at a lot less money. It is a very hard and dense wood but is a little hard on tools. Another wood that we''ve seen good prices on is Purple Heart which is also very durable and rot resistant but a bit hard to work as well.
