I need to replace about two foot of teak toe rail on my 69 Morgan 30. Did you make the toe rail yourself or were you able to purchase it already shaped?
A few years back we did the teak toe rail and rub strake on a Cape Dory Typhoon. The toe rail looked very similar to that done by the OP. We used 1x1 stock (nominally 5/4) and were able to achieve the needed curve as we installed. This looks to have been done the same. It's a worthwhile project and looks nice.
