---Suggestion: I tried this on a Windsprint this year and it worked
fine: Instead of a square mast made of the recommended 3/4" stock,
consider making the mast round by cutting the raw 3-1/2' wide boards
diagonally, from the 2.5" mark at one end to the 1" mark at the
other; with these pieces (I used 6, for a hexagon) and employing
birds'mouth joints, you can make a rough hexagonal mast that is
easily rounded with a plane and 40-grit sandpaper. by plugging the
bottom with a trimmed 4x4, you can also make (tailor) a round foot
that will fit into the partners and foot. If your sail is laced to
the mast, the rounded shape will reduce drag; if your sail is made so
it slips over the mast with a long pocket, rather than using guides,
laces or parrels, it will significantly inprove sailing and upwind
performance. (Obviously, only works on mast-fastened sails, not on
lugs). JR Sloan

Thanks to Derek and John for the advice... Dynamite's use of the
word "from" is an excellent tip that extra work will be involved.

I've got some building pictures up at:

You might consider making the mast round, to allow it to pivot.
Especially when the snotter is taut the mast and sail tend to become
of a unit, and want to pivot together. With a non-pivoting mast the
snotter will change tension from one tack to the other.

Hi Steve

I'd say you are correct all round. Number sixteen in the key says
"Supporting feet of mast step _from_ 1 3/8...." [my emphasis]. Like the skeg
in step fifteen, he's giving the dimension of the bit of wood you need to
start with. Where a part is evenly dimensioned (like step eighteen's
foresheet stiffener) the word 'from' does not appear.

Cartopper is a favourite - one of those plans I own 'just in case'. Do you
have any pictures yet?

cheers

Hi folks,

So I've been staring intently at the Cartopper plans and
building key, trying to find the Bolger-nature in the mast step, but
obviously my level of enightenment isn't up to scratch. In order to
position the mast step as shown (i.e. *not* parallel to the bottom
panel) I'm assuming that one must taper the mast step supporting feet
(#16) from the 1 3/8" x 1 1/2" x 7" sticks specified in the building
key. I'm further assuming that the square hole in the middle of the
mast step is a little more than 1.5" square to accomodate the square
mast for the leg o' mutton rig.

Payson unfortunately doesn't say much about the mast step in the
Cartopper building article, and the Gypsy mast step isn't the right
example to follow in this case.

Am I on the right track here?

Thanks for any help,

-- Steve
