it takes between putting her into reverse and actually moving backward with
flow over the rudder is what can take several seconds with a folder… If other
things are happening nearby (current, wind, pilings, etc.), these few seconds
can seem like a very long time!. Back in the mid 70’s I was crewing on a
C&C 39. The local rock star sailmaker was onboard for an event on Lake
Washington related to Seattle Yacht Club’s Opening Day parade. A few adult
beverages may have been consumed in the process of crossing the lake to join a
party at another competitor’s lake front home. When it was pointed out to
the rock star he was pointing the 39’s bow into a covered slip, he quickly hit
reverse (A4 engine, Martec folding prop) and added throttle. With the standard
delay in actually retarding the vessel’s forward motion the 39’s forestay
(Stearn’s twin stay IIRC) made a noticeable twanging sound as it hit the metal
roof over the slip. It was hard to find the rock star at the party that
afternoon. Years later that rock star became Calypso’s insurance agent. I
don’t think he ever forgot how long it takes to reverse direction with a
folding prop. Martin DeYoung Calypso 1971 C&C 43 Seattle

Subject: Stus-List Folding props I was not referring to feathering props. As
I understand them, they are designed to be about equal in forward or reverse.
My former Max-Prop 3 blade feathering prop was excellent and relatively quickly
got the boat going in reverse. Any geared folding 2-blade prop will get a
boat moving in reverse--just not very efficiently--especially if it is
optimized for forward motion and minimum drag when folded. The time it takes
between putting her into reverse and actually moving backward with flow over
the rudder is what can take several seconds with a folder.. If other things
are happening nearby (current, wind, pilings, etc.), these few seconds can seem
like a very long time!. Charlie Nelson C&C 36 XL/kcb Water Phantom
