Setting The Adventure 40 Free


After the Eric de Jong designed Adventure 40 came to naught frankly, my first inclination was to simply say screw it, take all the Adventure 40 chapters down, and get on with my life and running this site.

But there’s a better way:

A New Model

I’m made the Adventure 40 available to anyone who wants to build the boat.

  • No licensing fee for using our specification.
  • No equity in a company that builds the boat.
  • No licensing fee for calling the boat the Adventure 40.

Zero, zip, nada.

Sweet Deal

And yes, this is a pretty sweet deal. For absolutely free, a building company gets:

  • A specification for a boat based on my experience, that has been improved and battle-hardened by two thousand comments.
  • A known viable market for said boat. (Yes, there are people waiting in the wings who say they are ready to make a deposit.)
  • A framework for a company that will be able to build this boat at a profit.

Sweet Resource

Even if a person or company is not interested in building an Adventure 40, there’s value here as a specification to:

  • Measure prospective secondhand boats against.
  • Provide ideas while designing larger and more complex boats or even smaller and even simpler ones.
  • Provide a framework for those building their own boat.
  • Provide ideas and a gear list for those refitting an older boat.

Still Copyrighted

That said, I do need to make clear that all of my writing remains copyrighted with all rights reserved. You can use it to build a boat, but you can’t copy it and publish it in any way without my express written permission.


Of course, like open source software, all of this will be provided on an as-is basis: you get to use it all, but that’s all you get.

So if a company or an individual building the boat wants me to, for example:

  • Clarify or explain a point.
  • Expand on a chapter in more detail.
  • Advise on a design decision.
  • Visit the prototype and advise on changes.
  • Advise on marketing or sales.

I will charge for my time and expenses. Not only is this fair to me, it’s also fair to you, the members of Attainable Adventure Cruising, since you will no longer be subsidizing my work on the Adventure 40.

Of course, AAC members will still be able to comment and ask questions on anything I write about the boat.

And, if you think about it, this is totally in keeping with the Adventure 40 unbundling core principle.

I’m a Reporter Only

I will continue to write about developments with the Adventure 40 without charging anyone, but as an unbiased reporter, not as a promotor of the boat, and only if I think that the article will be of interest to the membership.

And better still, now that I have no financial interest—not even a nebulous future one, as I did before (possible royalty)—in the Adventure 40, I can truly be unbiased, both in fact and in appearance.


One more thing while I’m writing about my new direction. I hereby warn everyone involved in the Adventure 40 not to give me any information that they don’t want to see published—I will not be bound by any requests for confidentiality or non-disclosure.

I have always thought that the whole project should be totally open, warts and all, but now I’m making that official.

Straying From The Straight and Narrow

Of course there is a 800 pound gorilla in the room: What happens if someone builds a boat that does not meet the Adventure 40 specification as we created it on this site? 

I will call them out in an article. And nope, there will be no compromising. Great boats are not created by compromise, they are created by vision and sticking with that vision.

Sure a builder can call a junk boat the Adventure 40, but how many will they sell after I, and all the people here in the AAC readership who have given so much in the comments, call them out on it?


I know this new direction might come as a shock and even a disappointment to many of you but, after much thought, I do think it’s the best way forward and one that will result in a better boat in the long run.
