The Planning Stage - For this high end mega-yacht visual appearance is just as important as structural integrity, safety at sea, and functionality. In order to show the visual impact of changes that would occur to the vessel we would need an accurate model developed, however, the new owner did not have the original CAD files.
I began developing the 3D model in preparation for planning the new arrangements and radar arch. DNC of Mobile, AL later arrived and took their own measurements as they would be developing the materials to build and install the final mast system and bottom job. While mine were to be dimensionally correct to insure integrity of the view, theres had to be measured to fit a model which I had not seen to replecate.


Step 2 - To expedite the process we began by developing only the cockpit area to show the owner and agent different design ideas. Since we didn't know what the final design would look like we used a generic wood pattern for the teak deck.


CONCEPTS for the After Deck Section

These views are a collection of in-process renderings that were built on top of the models first stage. This section was also used to begin building out the remainder of the yacht. At this point we were more interested in giving the owner and agent ideas to work from.


Step 3 - After the yacht arrived at the Kennedy Ship and Repair graving dock we began taking dimensions and photos to continue developing the project for the client to see well in advance of cutting away material.

As you can see in these actual photos the stowage/freezers take up a large amount of space on the lounge deck. These are to be removed.
To do the job correctly we must first measure and document the entire boat to make sure that the 3D imaging is representative of the actual vessel.

Step 4 - We have now finished a general overview of the entire yacht. The purpose of this next group of renderings is to show how the radar arch and the preferred cockpit design will change the overall appearance of the vessel. (We replaced the actual vessel name and home port to protect the clients identity but the style is to be the same.)

At this point we've eliminated the seat cushions until we can obtain a color swatch from the client. In the last image you can see some of the detail in the ring antenna closup. You can also see how much is NOT shown in the closeup as the 3 dimensional facets that make up the images become more visible.

These images, along with matching AutoCAD drawings, have now gone to the naval architect where they will be reviewd for fitting into their own programs. Any major changes they suggest can be brought back into the original drawings and imaged out for the client to review if necessary.

Actual Photos
The following images show the progress up to the end of 2004. The old "T" mast was removed and the entire vessel covered. The refrigerator and storage boxes were removed along with the yachts windows. Work was also started to sand down every blemish and rebuild the surface to a matching height (fairing) before repainting the entire vessel.


Inside the shop work on the new radar arch and mast began. It was later installed in place of the old "T" mast.

Plans for the new teak deck were made and sent off. As soon as the new cockpit deck was faired the partially assembled teak deck arrived in a trailer and installation began.


Beneath the hull the original surface drive system was completely removed and tunnels installed along with new propellers and rudders. The following shows progress made up to our departure in December.


The surface drive system which never worked to its potential was converted to a traditional prop and rudder giving it 12-15 knots.


And here is the finished product in the graving dock and in the water. A well pleased customer left with her to head back to the north east.
