In the name of accuracy, here
is a kind of invisible detail
of the mastfish. If you want
to go that far, you will have
to Boolean a box out of the
mastfish to end up with this
slot. The mast would be slipped
into this slot and then locked
down by the mastlock. Essentially,
a large block of wood that
was on one end shaped like
the mast and once inserted
held the mast securely. |

 |
2.
I expect the back side of
the mastlock to be somewhat
slanted, so that gravity would
drop it down against the mast
contour. It's an ingenious
device. |
|
 |
3.
Next, put a lid on it. Create
a box with these numbers: |
|
|
4.
Rotate it, or pull the points until
it is slightly above the mastfish, and
parallel to its top surface. Then pull
the back point to get a siluette as
you see here.

5.
Unless you have KW Edge Smoother
by now, select the two mastlock
(oh, yes, before I forget,
name the box: "Mastlock")
top polygons and bevel them.
Just for grins I beveled the
bottom polygons as well, giving
them the same treatment as
the top (including the gap
elimination and point merge
as described below). |
|
|
6.
To eliminate the unsightly
gash, in the sideview, pull
the points on top of each
other and do a fixed point
merge with 10 mm selected.
Two points delete and you
are ready for the next step. |

7.
Notice the now smoothly connected
polygons. Bring the old mast
stump back into play, and
take a Boolean bit out of
the lid. Which leaves you
with three options.
1.
Live with the stress line.
2. Select and cut and paste
the affected polygon, or 3.
cut and triple it as you did
before with the oar-ports.
Your call.
Since
the item is very small, I
decided to just cut and paste
the poly. Stress lines relieved.

The next item should be the
T-shaped yard supports. They
were removable as well, as
least the rear one, to facilitate
lowering the mast, after which
time it could be set up again
as added support for the yard-arm.
It is suspected that even
the mast might have been lowered
upon the yard-arm supports,
(maybe that's why there are
three of them) to provide
added deck space during the
hectic disembarcation and
boarding phases of the raid.
Obviously, the most complex
part is the top crossbar.
On the 50 mm grid, lay down
these points. |

|
 |
9.
Select the points as
shown and connect them with
an Open Curve. Then select
the bottom twp points, and
connect them with an Open
Curve. |
|
 |
10.
Center the points in
X. |
|
11.
Select all of the points sequentially,
and hit <p>. you will
have a polygon. |
