A few years ago a replica of Columbus' ship "Nina" sailed into the local
harbor. The tiller was a tree from Brazil about 12 ft long. What a treat
to see a heavy ocean going wooden vessel from that era. Everything was
HEAVY duty.
Of course building your tiller would be much more difficult than just
using a tree.
The connection of the tiller to the rudder depends on the specific
rudder design particular to your boat..whatever it is..you have not told
us. Often 40 foot yawls have wheels, but not always.
Your boat was probably designed by some "famous" yacht designer
and there are probably specifications for the rudder, hardware,
etc..(length, etc.) I wonder what happened to the old one. Can you
re-use the hardware and build another?
Some of the rudder/tiller assemblies I have seen on some production
boats are so poorly designed, they break easily if someone falls on them.
Essentially, you laminate some White ash or other strong non brittle
wood to the approximate shape and after attacking it with saws, chisels,
draw knives, spoke shaves, carve it to fit your hand so you can hold on
to it.
The rudder end usually has a fitting made specially for the top of that
rudder and are often heavy metal tangs that bolt to the base of the
tiller and fit over the top of the rudder. But your rudder could have
cheek plates, which I doubt since you say it is a fiberglass boat.
Look at other boats in the yard. Copy their tillers when you find a boat
like yours.
Or...just order one from the marine store like West Marine.
Please let us know what you come up with!
