SIMPLEX WORM STEERERS
For excessively raked rudderposts, Edson offers a Simplex
with the Shaft Universal Assembly on the wheel shaft and an
exfra Self-Aligning Bearing for the needed forward wheel shaft
support. This combination can reduce the wheel angle by a maximum
of 30" up or down. That is if the rudderpost is at 45" to the
waterline the wheel can be angled at only 15". Edson feels the
maximum angleof the wheel should be no more than 20" . Likewise
on near vertical rudderposts the same universallbearing
setup can be used to give the wheel some aft rake. This angle is
important as it will give the helmsman room for his knees while
the top of the wheel is closer to his arms
If in doubt as to steerer size or if the boat is very heavy,go larger.
Do Not compromise the final size.
For those boats where the rudderpost ends at the cockpit
