Does anybody reading this have experience with the North Power XTR II
mast extension, which was put on the market, I believe, in late 2006?
If so, I'd much appreciate receiving any remarks you might wish to
make concerning its advantages and disadvantages.

What is the length of the lever/crank from end to end?

Clark,

Someone said "A luxury once tasted is a necessity."
For me, being able to adjust the downhaul on the water (small, inland
lakes, large [e.g., 10.5] sails, gusty winds) is worth a lot.  I very
much prefer to avoid returning to the launch (especially if I've
worked hard to get upwind) to readjust my downhaul -- if I cannot get
the desired results using an adjustable outhaul system.  I'm also the
kind of person who enjoys tweaking things.

So, for me, knowing what I know now and having tasted (and valued)
the
luxury, the answer is "Yes, I would buy a North Power XTR again".

<end of reply>

I'd also add that for me, when used on the Mistral Prodigy with a
***-like mast foot, I sometimes have problems releasing downhaul
(something I don't do as much as increasing downhaul) but there is a
work-around.

To add downhaul, I let the sail fall in the water on the tack that
allows to crank/lever to not be underneath the mast.  Then, adding
downhaul while on the water has been very easy (and enjoyable) for me.

Other disadvantages that I've experienced are:  (1.)  You need a
europin mastfoot, (2.)  I (and others) have problems with the newest
cleat/gear not being able to get a good grip on the latest generation
downhaul line (see the posts under "formuline in power-xt"), (3)  it
took me awhile to come up with a way to thread the downhaul line
through the sail pulley and the Power XTR mast extension so that the
lines didn't cross or chafe, and (4.) $200 made me stop and think
awhile.

To answer more questions:

1.  The type of sail doesn't appear to matter.  I routinely use the
Power XTR on large sails (e.g., Ezzy Infinity 10.5 with a sailhook).
2.  When one is releasing downhaul, the end of the lever/crank is
extended about nine cm below the intersecion of the mast extension and
the mast foot.  When the lever/crank is not being used, it is
vertical.  I tuck it inside the sail's foot.  To add downhaul, I move
the lever/crank from the vertical position to (almost) perpendicular
to the mast.  There is a small lever that you flip to indicate whether
you're trying to add downhaul or loosen downhaul.  When you're sailing
the crank/lever is left in the "add downhaul" position.

Hope this helps,
John.

Hello John;
Thanks for your reply.
I believe that I share your sentiments re this device tho I've not
used one yet. i.e. I too sail on a gusty lake and would like to be
able to adjust downhaul on the water, IF outhaul adustments don't cut
it.

Important questions for you:

1) Have you successfully resolved the slippage problems you were
having with the XTR 2 (as opposed to XTR 1) rotary cleat plate ? If
so, how so?... with the modified line you wrote about in a previous
posting.?

2) What is the end-to-end length of the lever on the XTR 2?

Clark

Clark,

1)   Yes, I have successfully resolved the slippage problems by
replacing the downhaul line with 4mm Marlow Excel Polyester Double
Braid (West Marine #4523130-purple) cut carefully (no rough edges,
etc. that increase the diameter of the downhaul line) with an
electric
knife.  I have rigged 6-8 times with this line and am happy with it
(especially now that I know the electric knife "trick").

2)  The end-to-end length of my Power XTR I lever/crank is about 13
cm.  The distance between the center of the lever/crank's mounting
bolt to the end of the lever/crank is about 11 cm.

Please note that on this forum, we sometimes talk about several
models
of the North Power mast extension.  I have the Power XTR I (42 cm
length) that I've upgraded with the new cleat/gear.  Others have the
Power XT.  Using the following web page as a beginning point, you may
want to check out the differences between the models.  I prefer the
XTR for large (e.g., Ezzy Infinity 10.5) sails (that I use with a
sail
pulley).
