yacht sketchup model

Andrew is an architect, designer of boats and SketchUp aficionado.  He runs summer SketchUp training courses from his studio in South Pelion, Greece.

His boat designs are on .

His website is here:

When it comes to boats and boat design, I'm a bit of a 'newbie'. I really got interested in boats when we bought a house in Greece and built my first boat here in 2008.  After that, I got the bug which led me to start designing them (I'm an architect so that sort of thing is in my blood!)

I'd been using SketchUp 3D software for my architectural work.  Its ability to create models in 3D and manipulate them led me to explore how it could be used to design boat hulls.

After some trial and error, I developed a method that worked and designed a boat. I emailed it to Duckworks and Chuck was kind enough to give me a page here to feature my designs .

Since then I've read a few articles on Duckworks Magazine which relate to boat design and it crossed my mind that some of you might be interested in how I go about creating a design.

This article aims to show the reader how to draw a boat in SketchUp 3D software.  I hope it might be of help to those out there who have a design in their head and just can't get it on paper.  The hydrodynamics are not considered here and may be the subject of a future article.  In the meantime, I'll direct those interested to Marcus Bole's PolyCAD website where you can download his hull design and hydrostatic software: www.polycad.co.uk

I import my SketchUp designs into PolyCAD for hydrostatic analysis.

Please note that the subject of this article is a preliminary design for a 12' x 5' beam small skiff, created simply to show how to go through the process and give you the knowledge needed in order to make a better design for yourself!

The Software

SketchUp is available in two versions, the free version - SketchUp Make, and the professional version – SketchUp Pro.  I use SketchUp Pro but everything shown here can be done with the free version – providing it is not for commercial use.  You can download SketchUp here: www.sketchup.com

In addition to the free software, I make use of a few add-on pieces of software, called 'plug-ins'.

The ones used here are:

Extrude Tools by Tig

BezierSpline by Fredo 6

Let's get started!

After that we'll put surfaces between the lines to make the hull panels.

Then we'll flatten the panels to form the flattened shapes of them.

At this stage I want to see inside the box so I use the paint bucket command.  Create a new material, edit the colour to something you will notice, then reduce the opacity so that you can see inside.  The example above has an opacity of about 20%.

Use the view toolbar for a top view and then, in the Camera list on the top line, choose parallel projection.

Move the tape lines from the bottom face to the top face and add another tape line centrally from bow to stern.

Over these tape lines, draw the transom line and the sheer line.

For the curve on the sheer line, I use Fredo's Bezier Spline Plug-in.

I've added horizontal tape lines to the face to represent the high and low points on the sheer line and the motor mounting height on the transom.

The transom and sheer line, as viewed from the top, and the sheer line as viewed from the side.

I've also transferred the lines on the side view and top view across to the rear (stern) view so that I can draw the transom as viewed from the bow.

Using Tig's Extrude Edges by Vector plug-in, extrude the lines on plan view and side view, then intersect the edges.

From this view, you see that we now have the lines of the stem and keel, the chine and the sheer.

Again, extrude the lines, intersect, then delete the extruded faces.

The transom face and lines representing the position of the keel, stem, chine and sheer.

The next stage is to put the side and bottom surfaces on the hull, using these lines as the edges of the surfaces.

Just triple click to select everything, then click on the Sandbox, 'From Contours' command.

The above shows the faces that have been created.

Note that the curves drawn by SketchUp consist of a series of straight lines.  I used the default setting here but there is an option to adjust the number of straight sections in a curve.

Note also that the Sandbox tool has created a surface by drawing lots of triangles between the curve sections.

This is useful because later on, we can use a plug-in to twist each triangle onto the same plane as the adjoining triangle.  This will give us the true shape of the flattened hull panel.

One needs to zoom in and delete this extra surface.

Now put the bottom and side panels onto the transom.

I'm going for a seating arrangement of abeam at bow, stern and midships.  Plus side seats running bow to stern. 

The vertical supports will form part of the structural framework.

First go back and make sure that all of the hull parts are components. You've probably come across 'sticky' geometry by now.  Components and Groups are the way to avoid this and at the same time organise your model.

Then draw a large rectangle below the hull - and bigger than the hull.

Then delete everything except the surface within the hull.

Make this a component.

Same process, select all by triple clicking, intersect faces with model, delete unwanted geometry.

You can either have large scale prints made - which can now be had for a reasonable price at plan printing shops.  Several do an online service - email the drawing and they'll send a hard copy back.

Or dimension them so that you can mark them out on plywood yourself.

After thoughts:

Scaling the model is easy but give consideration to what you want to scale.  For example,  you might want to make the hull longer but not the seats.  If so, scale up the bare hull and then add in new seats.

The illustration above shows two alternatives.  The boat that is closest has been increased in length to 18' with the height raised for a long shaft outboard.

The one in the middle is the same length as the original (12'), with the height raised for a long shaft outboard.

  Frames and frame thickness's

In this exercise, I haven't given the panels any thickness.  You could do this by pulling the flat planes out to the required thickness.

I haven't shown a stem, but by now you'll know how to add one for yourself!

Tiara Yachts Expands LS Line with Largest Outboard Model to Date, the 56 LS Holland, Mich., (August 27, 2024)  -  Tiara Yachts , the family-owned manufacturer of American-made luxury watercrafts, announced today the addition of the 56 LS to its portfolio of Luxury Sport vessels. The largest and most ambitious of Tiara’s outboard models to date, the 56 LS will feature the sophisticated exterior and interior amenities the LS lineup is known for, while also offering the power of four Mercury Verado 600 V12 outboard engines. “The Luxury Sport formula has been a successful one for Tiara, elevating the day yachting experience with versatile social zones and luxurious amenities. The 56 LS builds upon that foundation. Everything is amplified on this boat,” Tiara Yachts CEO, Tom Slikkers, said. “I’m confident our customers are going to be just as excited as we are about this addition to our portfolio.” Tiara’s first quad engine outboard model, the 56 LS will have a top speed of 57 MPH, making it one of the fastest Tiara ever built. The integrated electronics package includes Garmin ®  Marine Navigation Systems. The exterior of the 56 LS offers boaters several social spaces including a fully equipped galley that overlooks the aft cockpit. Two unique aft cockpit module options focused on entertaining or fishing allow each vessel to be customized. Port and starboard Hullside terraces expand the beam by more than six feet. Below deck, two staterooms and two private heads can comfortably welcome five guests for overnight or extended stays. “Our LS line has been a favorite of our customers and we're eager to showcase this new addition to our portfolio,” said Andrew Bartlett, Director of Design at Tiara.  “Our customers will find multiple features onboard that allow them to enjoy the water, entertain family and friends and comfortably stay overnight. As outboard models continue to have a resurgence in the boating industry, we’re excited to introduce another Tiara to the market.” The launch of the 56 LS comes amidst several milestones for Tiara Yachts including: ·       The celebration of its  50 th  year of business ·       The launch of the newly  revamped 43 LE ·       The EX 54 being named a   Boating Industry  Top Product of 2024 The 56 LS will be debuting at the 2025 Miami International Boating Show. Can't select certain groups from converted models I have been having this problem recently. This file was originally created in vector works and exported as an obj. I converted it using transmuter and everything seemed good but there are a few groups I can not select. They show up in sketchup but don’t show up in Twinmotion. I thought that maybe it was the grouping so I exploded everything and it still didn’t work. I updated to 2024 SU and that did not work either. reboot and restart and problem still there. I am on a Mac, M3 max with 128gb ram on sonoma 14.1 See images attached and link below to model. https://www.dropbox.com/scl/fo/b0ocmnd4ny28avmoi80sx/ACMwUzBLn6edK7zSMF4okXQ?rlkey=8yha7pyy9hg03s5ic1lghie0u&st=jrb0ccrf&dl=0 So you didn’t have any problems selecting those groups that I can not select? I get that the model needs maintenance on flipping a couple faces but don’t think thats what’s keeping me from selecting a couple other groups Correctly oriented faces are for viewing in Twinmotion. Regarding selecting other groups, you are the only one who knows what those groups are. Got it. The rounded edge and window frame highlighted in the image I attached are what I can’t select and thats what is not showing up in Twinmotion but it is showing up in your Twinmotion model and you have them both selected so I am thinking you aren’t having issues selecting it. I still am, however, and have no idea why The groups are selectable and can be moved. I uploaded a video of me trying to click those groups to the same link https://www.dropbox.com/scl/fo/b0ocmnd4ny28avmoi80sx/ACMwUzBLn6edK7zSMF4okXQ?rlkey=3gezwm1ulx1xpvjufb769un53&dl=0 Probably the way the objects and geometry are grouped creates selection problems for you. Try with View > Component Edit > Hide Rest of Model and look in Outliner to see the nested groups. Just tried that but I can’t click with of those items so it doesn’t do me much good unfortunately. I also have Asus ROG STRIX 18" laptop that I opened the model on and it doesn’t work there either so now I am very curious how you are able to select those groups on your computer but I can’t on mine. Thank you for your help on this. Will you send a link to the model back to me? I am interested to see if by going through your comp somehow fixed it or if I still can’t click it Your model is a group inside another group. After 2 double clicks (4 clicks total), I am inside the second level of grouping and I can select and move the objects that you showed. There’s weird scaling of groups in your model. I expect that has a lot to do with this issue. I can’t select the curved surface object at the top of the superstructure either. I don’t know whether this is due to the Vectorworks exporter or Transmutr. Can you export a different file type from Vectorworks to import into SketchUp? Dude! I think you nailed it. So, most of the time, when I convert a file, it comes in with a mess of geometry BUT the interesting part is the scaling. It doesn’t always hold the scaling and in this case the boat was like 1,700’ long so I used the ol’ opt+measurement tool to scale to the correct size. I just opened the file before scaling the model and I can select the items so I think I need to regroup and scale down differently. Still would love to know how the other guys were able to open without issues, 485 IMAGES Luxury Yacht Yacht 3D SKP Model for SketchUp • Designs CAD Yacht Yacht 3D SKP Model for SketchUp • Designs CAD Yacht-design 3D models Luxury Yacht SketchUp 3D Model .skp File Download COMMENTS Yacht 3D Models for Free Download 92 Free 3D Yacht Model files for free download in .Blend .Max .Obj .Skp .C4d .Fbx .Ma .Stl with high quality, low poly, rig, animation, printable.
