To demonstrate the ease with which you can design boats using the Nautilus System^TM, we've put together a sequence of design screens showing the development of a chine hull planing boat with a developable top plate.  The time estimates are realistic and are not based on the fastest possible time, and the elapsed time values are cumulative, from the beginning of the design session.  Although this example does not describe each step in great detail, we believe that you can see that the Nautilus System^TM is the fastest and easiest hull design and fairing software on the market.

1.  Create a simple starting shape for the hull using the "Create Boat" command.

Elapsed Time:  1 minute

2. Section view after adding one station or column.  Vertical hull lines are columns and longitudinal hull lines are rows.

Elapsed Time:  2 min.

3. Profile view after adding seven stations and fairing curves by eye.  Note that the defining points lie ON the hull surface.

Elapsed Time:  6 min.

4. Section view after adding seven stations and fairing curves by eye.  Note that the defining points lie ON the hull surface.

Elapsed Time:  6 min.

5.  Plan view after adding seven stations and fairing curves by eye.  Note that the defining points lie ON the hull surface.

Elapsed Time:  6 min.

6.  Curvature curve (drawn on top of sheer curve) magnifying unfair points.  Note that all inflection points are indicated by the intersections.

Elapsed Time:  7 min.

7.  Faired sheer curve created by adjusting the defining points with the Move% fine tune command until the curvature curve looks smooth.

Elapsed Time:  9 min.

8.  Faired chine curve showing smooth curvature curve.

Elapsed Time:  11 min.

9.  Plan view showing unfair sheer curve.

Elapsed Time:  12 min.

10.  Plan view after fairing the sheer curve with the Move% command.

Elapsed Time:  14 min.

11.  Gaussian curvature color mapping.  It can be used to check the surface fairness or plate developability (indicated by the dark blue coloring).

Elapsed Time:  16 min.

12.  Gaussian curvature color mapping: Section view.

Elapsed Time:  18 min.

13.  Gaussian curvature color mapping: Plan view.

Elapsed Time:  20 min.

14.  Lines drawing of the hull.

Elapsed Time:  22 min.

15.  Stations created for performing hydrostatic calculations.

Elapsed Time:  25 min.

16.  Partial hydrostatics output for a given draft, trim, and heel angle.  It will also balance for input displacement and LCG.

Elapsed Time:  26 min.

17.  3D mesh view of the hull.

Elapsed Time:  27 min.

18.  Another 3D mesh view of the hull.

Elapsed Time:  27 min.

19.  Section view showing developable top plate created using the "Develop Patch" command.

Elapsed Time:  30 min.

20.  Gaussian curvature color mapping showing developable (dark blue) top plate.

Elapsed Time:  32 min.

21.  2D layout of the developable top plate, marked with all of the frames.

Elapsed Time:  34 min.

22.  Partial set of tabulated numbers for the edges of the 2D plate layout .

Elapsed Time:  36 min.
