All of the Westcoast 46's were built using Jatoba for the floors. it is also called Brazilian Cherry. It is beautiful, tough and relatively inexpensive. It's used a lot in houses now, so you can find it easily.
We have teak trim and it blends well with the teak. It is one of our favorite features on the boat. It always looks good and requires little maintenance. I was told by the boat builder that the one drawback to using it was it was hard on tools. I highly recommend it, but I didn't have to cut, drill and install it.
