[C38] performance

[Patrick Harpole]

Joe,

     Can't Ken do the same thing with his present prop?  That is..a little
reverse to attain steerage then neutral?   Does another prop do a better
job?  I am obviously a "Wuss" sailor and anything to get the job done ...I
have fairly long mooring lines and let someone walk me out if the prop-walk
is not to my advantage..sometimes it is.

Patrick

P.S.  To determine  prop-walk put engine in reverse and look over the port
then starboard side..which ever way the water's flowing your vessel's
turning the other way.

Ken,
    I have a late model 38 with a 4 cylinder engine but solved the backing
problem. I put on a two bladed Max-Prop. (I now wish I had gotten a 3 bladed
which costs more but does an even better job providing power in rough seas
and  backing.It is a matter of $$$.)
the 2 blade Max prop will be a huge improvement over what you have. It is a
feathering prop so it is just as efficient backward as forward. What I do is
put it in reverse, give it a little power to get the boat moving and then
shift to neautral -as the boat coasts back I alternate - a little reverse, a
little neautral. You can make it back out in a perfectly straight line. The
downside is the max Prop (do not accept substitutes) will cost a bit but it
is one of the best investments we ever made. Because the max prop is
powerful in reverse you can use it to stop the boat coming in. Make certain
that the pitch is set to the specs recommended for your boat when it is
installed. Joe Launie/Macavity

I recently bought a '83 Catalina and I am in the process of getting to know
the boat. It has the standard 21 hp Universal and two blade prop. My big
problem is when I am trying to back out of my slip the stern moves hard to
the port no mater which way I turn the wheel. My slip is pretty tight length
and width wise.

Is there some way I can get more power and control without getting a bigger
engine? What's the best way to turn the helm when I back up in a tight area
to keep the stern swinging to the left?
