My Riva Aquarama Plans

My craft (which I am still working on the ribs before I set her up up-side down) is 33' w/ 10' beam.

That looks great. I am fond of the bootlegger myself.

Though the beginning of this thread is a few years old I think its still relevant to comment regarding plans. Speaking from having gone to law school here in the USA. Photocopying someone's plans and reselling copies generally is unlawful unless the copyright has not been maintained and therefore has become part of "the public domain". I know that the plans for "Flyer" the hydroplane racer offered by the ClassicWoodenBoatPlans site are public domain plans. They originally appeared in a 1930's book by MotorBoating in their Ideal Series. Copies of plans for Flyer can be widely found. Some for $4, some for much more. Find the book and they're free.

Further, one may not make copy a designer's copyrighted work and offer it for sale, however, one may "be inspired" and draft a new set of plans, even noting the architect/designer by name from which the inspiration came, and legitimately sell those new plans as their own. In other words by tweaking and improving upon the original plans they become new plans. Unlike a patent in which similarities may be grounds for infringement, a design is the least protected since small changes will make it a new design. We all know that when doing a term paper in college, you never plagiarize, you list your references, unless citing a direct quote, and then you "paraphrase" in your own words. Someone can build a typical mahogany runabout, give it a white bottom, and say "inspired by Riva". It may look very much like a Riva and just may wind up being an improvement over the original.

However, copying original works for resale without regard for copyright laws is always illegal. I'm formerly from the US Dept of Justice, US Atty's Office, Securities Fraud and Public Corruption section. I gave up years of law for love of boats and yacht design. I'm a happier camper for it! - Scott

If you buy the books written by Carlo Riva then you get the plans with them.

[cudashark]

This is true Arie,

If you can find the only book with any plans in it. That would be "Carlos Riva The man the Legend" Something like that. Any how the book goes for 200 to 300 dollars US and then you have 8.5 X 11 inch drawings of a "plank on frame" constructed boat.

All the CAD work still needs to be done as well as the new scantlings. I know I have done it.

I have redeveloped the design into 3 models. A 21', a 28.5 ' and a 33'

It costs about 500 dollars per ft.

Good luck

Yes, I bought a pair of books when I was in Europe a few times ago I think I paid 150 Euro.

Now I am lofting the aquarama in corel so I can make a model boat to the size my grandson wants 4 to 5 foot with a whipper snipper motor in it.

If people are interested in a copy, let me know.

I believe that plans you're talking about are intended to be integral part of those books, and hence copying and distributing them is not legal.

[Arie Cornet]

Those plans might be not intended to be duplicated, but taking the approximate measurements to make a new line plan to make a model of a type that is not anymore in production for more than 3 decades, I can't see if there was a patent on the boat it could only have laste 16 years from the first day of public showing which includes start of production

[daiquiri]

Sorry, I had misunderstood you. Thought you were talking about copying and distributing plans from the book...

Here is a tale that should find resonance here. Peter Freebody was one of the greatest builders of wooden boats on the River Thames. Regretably he died just before Xmas 2010, but here is a link to an article about his recreation of a Riva.

Dear All,

There is .fbm file for this boat.

cudashark,

First of all good job on your approach to design.

Reading this thread is very informative because we are able to see where old paper plans do not necessarily represent the final form for a vintage hull.

Also, many have talked about, an exact copy would not lend itself to improvement, by leveraging NAs increasing knowledge base and leveraging 3D CAD tools in hull design for high speed design and construction.

If I had access to the original vessel (Hull), especially one with engines/equipment removed, I would invert it and do a 3D scan. Bring the scan into a 3D modeller, cut in half (symmetric hull) remove any imperfections (I may have to re-loft) for a constant curvature fair surface. Then mirror and provide surface to the NA for analysis. The NA can then improve (depends on the priorities) and finalize the shape. This then would be the new "improved" hull.

So you have the opportunity to scan the hull you are building to look at improvements.

[Arie Cornet]

Yes, I have remodeled the original plans, and then because this is for a model boat 4' for my grand son redrawn the after hull as the size increases the viscosity of the water in relation to the size.

Thus there is always changes not necessarily improvements
