what''s the deal with the mast tiller?

Posted by fgljff (fgljff@…>)

I understand the concept of this gadget. But what I want to know is how to
attach it. I have a
wing mast (F-25). Also, I haven’t looked at it closely, but I’m assuming the
boom is attached
by a clevis pin to a standard gooseneck, right? And how does the sail bend on? I
have a stack
pack but can’t find any instructions for attaching it to the sail. It looks like
there are two lazy
jack lines that attach to the mast top and then two lower ones. Whew, it’s a
passing strange
rig, mate. I’ll be pondering this one for a while, just trying to get the rig
set up.

On my F-25 the mast tiller has a hole near the aft end. A line goes
through this hole and is stoppered with a figure-8 knot on the bottom.
The free end of the line goes through a metal clam cleat on the bottom
of the boom. This line is adjusted to give the smooth mast-to-sail
transition that keeps the airflow smooth. (See the picture on the
first page of F-25 manual in the Files section of this Yahoo Group
[it’s in the “F-25 Info” folder])

My mast has a metal track on the back that the sail slides ride on. To
bend on the sail, I have to unbolt a short section of track just above
the gooseneck and attach all the slides to the upper section of track.
Two people plus a spare webbing sail-tie (to tie around the mast and
bottom of the fixed track) to keep the sail from sliding down while
replacing the short track section helps.

My sail is loose footed with only the tack and clew attached to the
boom. Don’t know if this is standard or a previous owner modification.

If you have a Doyle StackPack then the lazy jacks should attach
directly to the StackPack.

idea of the process.

USA-built Freedom 25s have loose-footed sails as factory standard.
The rotation-limiter (mast tiller) is adjusted for smooth transition
of mast curve to sail on the LEEWARD side of the mast-sail. Herm

Where does the mast tiller attach to the mast? (By the way, my sail is also
loose-footed. I
think it’s standard on the F-25).

The mast tiller is integral to my wing mast. It’s located just below
the gooseneck. If you look at the (admittedly grainy) picture on the
top of page 23 of the F-25 Manual pdf file you can see the mast tiller
pointing towards the first stantion on the starboard side. It’s also
visible just under the boom in the picture on page 24.

Anyone who wants to investigate the wing mast-sail interaction more
thoroughly is advised to read Tom Speers paper on this topic:

Is it that thing that looks like two curved tubes?
