The parts and process included in yacht designing are

1) Propeller

2) Radar

3) Blueprint set up

 4) Hull

5) Garage door

6) Front seat

7) Middle seat

8) Rear seat

12) Photo rendering

Firstly, the components mentioned above are designed and then the assembly is done. After the final assembly, photo rendering of the yacht is done to create a realistic view. The procedure of yacht design is explained briefly in the form of flowchart.

       

1-Propeller

 

The propeller is the primary connection between the engine and water. The propeller affects every phase of performance - handling, riding, comfort, speed, acceleration, engine life, fuel economy and safety. In determining boat performance, propellers are second in importance only to the power available from the engine itself. Without the propeller's thrust, nothing happens.

 Part designing

 Create a new part. Draw a 2D sketch as shown in figure1 and use revolve feature. For revolve, select the axis of rotation and the sketch drawn.

 

 Draw a 2d sketch on top plane fig.2 and fig 3. Use solid loft feature for the fig below figures. For Solid loft, select the two sketches to create it into a single feature. Make sure the green balls are on same rectangle while using solid loft feature.

Then Circular pattern feature is used. Select the number of patterns required and the profile.

Add fillet on the edges of the loft. Draw the sketch and use extruded cut feature. Create a circular pattern of the created part. Change the color to the part as shown.

2- RADAR

Radars simply send the radio waves (within the range), and if there are any obstacles (ships or landmass) in between, then the radio waves get reflected back to the radar. Based on the time that took the radio waves to come back, it will calculate the distance and display the range on the screen.

Part designing- Create a new part. Start the sketch on right plane as shown in fig. and create an extrude and add fillet to the edges.

Select the edge of the extruded part and use offset entities to offset it with 3mm distance. Use extrude feature for this profile with a distance of 10mm and extrude it.

On the extrude part.select he face of and draw the sketch as shown and extrude it and add fillets.Select the profile and use pattern to create multiple bodies on the selected face and extrude it as previously.

      

Mirror the radar by using right plane. Select the bodies to be mirrored option and select the body.

ASSEMBLY AND PHOTO RENDERING

ASSEMBLY

For the process of assembly, go to Insert>Existing component, firstly insert the existing individual parts of the yacht. While importing the parts, they are placed accordingly with respect to the given dimensions because for all the parts the hull-deck surface is used as reference. So, they get automatically placed. The proper mate relations like coincident, concentric etc are given to the parts where there is a gap or assembly is not done.

Photo rendering gives the realistic view of the created model where the image shows appearance, lighting, scene and decals included.

After the assembly of the yacht, add the photo view 360 to the feature tab. It helps to show the rendering images with realistic environment and visualization of the design created.

                                                        

                                                

                                                    

                                               

                                               

                                              

CONCLUSION:The designing of yacht is done smoothly with the help of solidworks features even though the complexity of designing yacht make it looks difficult initially.The knowledge of rendering helped to visualize and get a realistic view of the model to be brought into real environment.Mainly the knowledge gained while designing yacht is, the exposure of when to use different features and tools to make the design and edit parts efficiently are known and gained knowledge in part designing, assembly and rendering.
