1. 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. Save your file as ship_tute15.lwo
8. 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.
