Re: Anybody 3D Modeled their boat?

There was an article in Proboat a few issues ago about a photogrammetry system for doing exactly this. (I'll try to dig out the reference.) You stick printed targets all over the hull, take a few dozen photos from different angles using a camera whose lens distortion is precisely known, and then calculate the shape of the hull from all the images. Very cool, and I think it only takes a few hours to do. Laser scanning / structured light scanning is also very cool. Scaling it up to boat size might be a bit harder than a desktop unit, but I can think of no fundamental reason why it wouldn't be worth a try. (No, I don't have such a system.) Definitely start with something small- it'll likely take a lot of fiddling to work out all the quirks and details before you try scaling it up to yacht size.

Do a search for 123dcatch
Thank you! That's crazy cool In their little video they did a renaissance bridge (Ponte Vecchio maybe?) so my little 36 footer should be no big deal.

All I need now is the sun to shine in Seattle. I'm figuring I will have this done late June or Early August no problemo

Re: Anybody 3D Modeled their boat?

I have the archtects drawings in cluding the lofted sections throughtout the boat. Digitezed solid model does me no good but I did make solid models of the deck, masts and sail plan. That is useful.

What do you use it for? Or anticipate using it for? recutting sails or new rigging or???

Re: Anybody 3D Modeled their boat?

This is the tool you need FARO Laser Tracker - Home

There are companies that will create the model for you. It will be expensive, but it will be cheaper than buying the tool to use yourself.

"Need" is such a strong word

But isn't the model +/- a few thousandths of an inch worth it?

<sigh> see this is the kind of 'logic' that gets me in trouble all of the time.

I think you can pick up a system for about $100K.

I'll have to do the math later but that seems pretty reasonable on a per micron basis. Once I do that, why... there will be no limit to the design simulations I can run through for my 71 year old $6,000 boat!

Oh please. Reasonable expense? You can't compare to original purchase price. I am speaking from experience, we spent $3K for our Pearson and have been spending way more than that on Blew Sea System equipment.

A proper Faro operator can supply you exactly what yo want.

I must admit you make a good argument, I really can't find a flaw in your impeccable good sense.

Don't worry though, I'll be sure to post up in the living simply minimalist thread on how much money I saved by using computer simulations of a new dodger instead of cardboard mockups and all that expensive masking tape.

All kidding aside, you could make a really amazing 3D model using a Faro system. Granted, it would cost about $5K for a simple boat though. It would really be an amazing project!

Back in the day, we tried to get a local power boat maker (Power Quest) to CNC machine the hull molds they were using. We attempted to sell the idea of repeatability. We were never able to sell them on the idea. Then again, they are closed now.

Um, don't need to. I have the line drawings, construction drawings and she's a multi-chine boat. NO problem at all once I figure out Autocad 3d. Just don't have the time right now.

Re: Anybody 3D Modeled their boat?

I 3d model everything I build no matter what the project or wither I am building it or some ones else will be doing it. I’m a protectionist, design intent and final outcome must be measurable and definable to me, and besides that is what I do. I do this professionally as one of the services of my company, having said that I am talking mostly about new items and boats to be built. Where it comes to existing boats and new parts, additions or modifications I do that as well, but to a lesser extent. There is a company in Vancouver that will scan your boat for you, this isn’t a cheap proposition, (sorry can’t remember the name right now), due to the cost most of my customers have always just had me develop a model from careful measurements, lines drawings etc. For my present refit I have not yet modeled the whole boat but simply the parts I intend to work on. At some point I would expect I will have the whole boat done. If you would like the name of the company that does the scanning I could find that out, but won’t be back in my office till after December 6th, contact me by PM.
