[Public-List] Reversing the A-30

[Gordon Laco]

Good morning Stephen -

I think what you are getting at is that between the weathercocking issue and
prop walk the boat will 'walk' herself up stern to the wind if one runs the
engine in reverse for a prolonged time while setting the anchor.  Here's
what we do.  Again, sorry this is so long...

When anchoring we line the boat up head to wind, or rather slightly to
starboard of head to wind.  When using the engine we give it a hard burp in
reverse  put sternway on then put it in neutral again.  Once the chain is
paid out sufficiently we let it snub gently then give it a hard pull with
the engine, again in one or more hard burps.  By starting off with her head
to one side of head to wind, you give yourself some 'room' for the prop walk
to occur before it becomes annoying.

When anchoring under sail, we make our approach with the headsail furled,
under the main alone.  We turn up into the wind with the main luffing then
use it to stop where we want to put the anchor by pushing the boom out to
the shrouds - effectively backing it and generating power in reverse.  Down
goes the anchor when sternway is on.... The chain or rope is snubbed when
enough is out.  It doesn't matter much if the boat has yawed while backing
down so long as the anchor gets its encouragement to set.

If it is windy and the boat starts 'hunting' back and forth we set a very
small jib (actually from a Mirror class dinghy) along the backstay sheeted
amidships.  That stops the boat's desire to turn downwind and she lies
peacefully.

I forget if I asked before... Is your boat the one I saw at jetty adjacent
to S.A.L.T.S a few years ago?

Soon we'll be sailing here and doing what I described above!
