18. No go to the other end of the control arm and bevel that polygon three times.
a) Shift 20 mm - Inset -25 mm
b) Shift 100 mm - Inset 0
c) Shift 20 mm - Inset 20 mm
19. Go to the front of the control arm and copy and paste the polygons as shown, into an empty layer. You'll use that as a Boolean object. The composite image shows the polygons involved and the result after the Boolena subtraction. The Rudder top now has a proper slot in it.
20. Neat little rudder, is it? Now all you have left to do is to "pin the tail on the donkey". That is get the rudder handle combination mounted on the pivot. After all of this work, save file as ship_tute17.lwo
21. Guess what will become an oar? How about the rudder control arm? Works for me. Select it, make a copy of it and paste it into an empty layer. Select the point of the knob at the end and with (t) move them toward the right, as show. The grid is at 500 mm.
22. Shaping the blade of the oar. Take the point on the leading edge of the arm and slide them as shown. Follow suit with the rest of them until they are in place. The second screen-grab is on a 100mm grid. You can easily see where this is all going to end up. A few cuts (blue line for the initial one) will soften the curve.
23. All the cuts are in place and you can shape the oar a little more. Blue arrows indicate the cuts.
24. Grab the two rows of points in the middle and use (h) to stretch them vertically...and the right image shows you what you want to achieve.
25. Now sqeeze the blade a little, use (h), and you will be left with a very passable oar.
26. On to the Rowing benches/ sea-chests. With storage space at a minimum on those vessels, they used sea-chests as rowing benches. Very practical. They were found with curved and flat tops. All heavily banded with iron straps. Make a disc and delete the lower half of the points. Follow with a box and you've got the sea-chest nearly finished. They mounted them on legs, I guess to keep the contents dry. Two more little boxes (one copied and slid) take care of that.
27. Now for the iron banding. Copy the sea chest to an empty layer. Take the knife and cut a slice out of the middle somewhere. Hit (H) (MODIFY/Size) and enlarge the slice slightly. It's your iron band. Delete the rest of the chest. Copy a few and spread them across the chest. Then select them, name them straps, and copy them to the chest. Use the same color you used for the rudder pivot and hub, to color the bands. I made them just a little more shiny.
29. And voila, one burly seachest. Now you realize, that at some point you will have to make 32 chest and at least 30 oars and distribute them evenly around the ship. I'll give you some pointers. Of course, setting up one quarter of the ship and mirroring the rest will pretty much take care of it, with some adjustments. On the 200 mm grid, stretch (h) the seachest to these dimensions. When you move the cests around, make sure none poke through the hull.
30. What remains is the sail. The sail will be fastened to the yard with hoops of rope. So, go forth and make some hoops. This is what we need. Open an empty layer with the yard in the background and create these points. Connect them with a Closed Curve.
31. Go to an empty layer with the curve in the background and create a small disk in the Front/Rear view.
32. Swap (') layers and go to MULTIPLY/Rail Extrude, set it to Uniform Knots = 20, and hit "OK". Name the result "Hoop".
33. Go forth and select, copy, and slide, until you have six of them, as shown on the left. Then mirror the bunch in the Z axis. Save file as ship_tute18.lwo
