[C320-list] Replacement Sails Dutchman A system

Scott, I'm not familiar with the various Dutchman configs, just ours which
I'll attempt to describe: it is a two block system, there is a continuous
line on which the two Dutchman blocks are attached and the free part of the
line runs freely through each Dutchman block. At the upper end is a small
single turning sheave with a rotating eye.  At the lower end is a fiddle
block with cam cleat.  The topping lift is attached to the small sheave at
top and kept taught when not sailing. The rotating eye allows the topping
lift to twist as it needs without transferring the twist down the rest of
the lift.  The fiddle and cam at bottom allows the tension on the
monofilament lines to be eased when not striking the main even while the
topping lift is taught. 

After the sail is up and drawing, I slacken the topping lift.  Before
striking the main, I tighten the topping lift, adjust the Dutchman at the
fiddle block to tighten the monofilament, then drop it.  Once down and
flaked, I use the fiddle/cam to relieve the tension on the monofilament.  It
all works fine as long as the monofilament lines are properly tensioned and
I'm not too far off the wind when I drop the main.  Oh, and I try to be a
few degrees to port of the wind so the sail slides don't hang up on the gate
screws.

So much to remember.  So few brain cells left with which to work.

My boat also came with the Garhauer solid vang and the Dutchman C system
("clothesline") with two mono-filament lines. One of the first changes I
made to the boat was replacing the springs in the vang with weaker ones
(from Garhauer) so that it wasn't so difficult to pull the boom down to
where it should be in light air. But that means that my vang is not quite as
rigid as yours.

Regarding the Dutchman, I now have the A system with 3 monofilament lines
and regret having made the change. With full battens, 2 monofilament lines
are enough, in my view, and I never had problems with the C system once I
got it adjusted.

Furthermore, I am not comfortable leaving the topping lift tensioned when I
put the boat away, since with a properly adjusted system this means that the
monofilament lines are under tension and bearing a good bit of the weight of
the mainsail. If you read the Dutchman instructions carefully you will note
that with proper adjustment. Quoting from the A system manual:  "Basically,
the flaked sail hangs off the control lines." I am concerned that this leads
to premature failure of the monofilament and (more importantly) to chafe
between the main and the monofilament when the sail is put away and covered.
I'd rather have the control lines relaxed and the sail tied securely to the
boom. As a consequence, I ease my topping lift whenever I put the boat away
so that the main rests on the boom and the monofilament is slack. As a
consequence, I don't really need the slits that were cut into my mainsail
cover, which seem to let in dirt, even though they are zippered.

To keep the boom from moving around (which is important--see below) I
support it using the main halyard secured to the end of the boom. You have
to secure it somewhere, so why not the end of the boom! The monofilament
control lines limit movement of the slack topping lift enough that it
doesn't chafe or get caught on other parts of the rigging.

Your idea of using a pennant to effectively shorten the topping lift so that
the control lines can be slack even while keeping a taught topping lift is
clever.  It occurs to me that you could get the same effect by splicing a
small hook directly into the topping lift a few feet up from the boom and
just hooking that to the end of the boom when you put the boat away, leaving
a small loop of slack topping lift. Or you could switch to the C system
which does essentially the same thing, albeit with more complex hardware.

Note on keeping the boom stationary: Shortly after I purchased my boat
(used) there was a post on this list about a boat where the vang bracket on
the mast had failed. The cause was determined to be excessive wear due to
the combination of improper vang assembly and constant minor motion of the
boom as the boat rocked at mooring or in its slip. It's important that the
stainless part of the vang fitting not be allowed to rub directly against
the cast aluminum mast bracket! There should be a stainless washer in
between. Without the washer, the vang will wear a groove into the center of
the aluminum mast bracket just from minor motion when the boat is not in
use. If this groove becomes deep enough the vang will "hang" in the groove
when you ease the main away from center line, creating enormous torque on
the bracket at the groove. 
Something has to give, and on the boat in question there was a failure of
the bracket. When I inspected my boat, I found the washer was not installed
properly, and that the groove was starting to form. I've had no problems
since putting the washer into the proper location between the lower part of
the vang and the bracket.
