I had always thought, like most sailors I suspect, that a naval architect sat down with his or her computer and over a number of weeks a fully formed design emerged. But, in fact, nothing could be further from the truth, as I'm learning watching Erik design the Adventure 40. Boat design is an iterative [...]
In Part 1 of this post I looked at the role that letting the interior drive the design and confusing the mission play in the birth of bad boats. Today I have three more ways that bad boats happen: Boatbuilders want to build as many hulls as they can to the same design. Stands to [...]
Buying a poorly designed boat is one of the most costly and heart breaking mistakes anyone can make. But maybe if we understand how bad designs come to be, we can avoid that.
With the Adventure 40 well and truly on her way to becoming a real boat that you can buy, I thought it would be a good idea to keep everyone informed of what's going on with a series of bulletins. This is the first. Andy Schell, over at 59 North interviewed me, in the form [...]
Exciting stuff to close out the old year and bring in the new. We have a designer/builder for the Adventure 40.
A single post summarizing Adventure 40—a reliable, simple, safe, fast and reasonably priced offshore voyaging boat—and the mission for said boat.
We continue our series on desirable offshore motorboats for those retiring from sailboats with a design analysis by AAC Technical Correspondent, Matt Marsh of the Artnautica LRC58 currently in-build in New Zealand, . Even if you are not interested in this particular boat, you will want to read Matts insightful analysis of hull form and cost considerations.
How many of us aging sailors sailors have secretly thought about a transition to the dark side? Come on, fess up, you know you have. Today we published my second look at what an offshore sailor really needs in a motorboat and look at a boat that might just meet those needs.
In the last few chapters of this Online Book, we have written a lot about hull construction materials and impact resistance. In this chapter I relate a true story about when construction strength and impact resistance were dramatically tested right before my eyes.
I have written at some length on watertight bulkheads because I think the subject represents an interesting exercise in risk evaluation, a process all of us who wish to sail offshore must become adept at, because if we treat all risks as equal, and try to guard against each of them equally, we will quite simply never leave the wharf.
The sad fact is that many, perhaps most, production sailboats are not built to take the loads imposed by even a moderate collision or grounding.
In this chapter of our ongoing Online Book "How To Buy an Offshore Voyaging Boat", Matt Marsh, AAC Technical Correspondent, explains the engineering and shares what to look for before buying an voyaging boat.
Matt carries on from the last post and examines how the various materials a voyaging boat hulls are built out of will survive a collision with a hard object.
Matt takes a look at the materials available that offshore voyaging boat hulls are generally built of and explains the benefits and drawbacks of each one.
This chapter is a slightly humorous but oh so important demonstration, in the form of a mock pub (bar) argument, as two experienced cruisers argue and compromise about what to fit into a 40-foot offshore sailboat and what to leave out. As you search for a boat you will be having the same arguments with yourself and your spouse. This chapter will give you a good framework to settle on what really matters in the boat you buy.
Now we are getting to the really hard part of specifying the Adventure 40, the interior.
