[C38] performance

[Charles]

Ken,
I too was a bit taken aback with the prop walk on the 38s.  It is much 
more than my last boat and I my experience on the helm on a couple of 
"J" boats which have significantly less.  I think this is a trade-off 
for our particular mast - keel configuration which allows us to point so 
well.  As far as props go, I went to the three blade Sailor prop and 
experienced what Phil is talking about in terms of the additional power 
these blades have over the two blade.  Again, there are trade-offs.  My 
three blade prop increases boat speed (over one knot at 2200 rpm for me) 
and reduces fuel consumption (I keep track).  It also has reduced drive 
train resonance, which really bothered me.  But, it does slow the boat, 
which I could have eliminated with Phil's $2500 prop (mine cost $500). 
I think your Universal is actually a 24 hp engine, which is a bit under 
powered, but I am sticking with mine as I still have other places to put 
that $10,000!
It took me a couple/three years to figure out the throttle technique 
(slow learner) and there are still situations that make me nervous such 
as high winds with crowded docks.  But, this prop walk can be managed 
with practice.
