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.
Sadly most boats, both power and sail, have interior arrangements that are designed to look good at a boat show, not work well offshore or when living aboard for extended periods while voyaging. Here we give you and explain, based on some 20 years of living aboard and voyaging, a guideline for eight things to look for as you shop for a boat.
In this chapter, John applies the theory of cycle loading that Matt explained in the last chapter to come up with solid rules you can apply to boat and gear buying.
Electric and diesel electric (hybrid) drives have become all the rage in recent years. But are they really a more efficient option for offshore cruising sailboats? In this post we take a solid and arithmetically rigorous approach, based on advice from two professional engineers with substantial experience of electric drive use on land, to cut through the hype and answer that question.
It's an all too common story: a boat that has been structurally fine for years while sailing inshore starts to come apart as soon as she is sailed offshore. This chapter explains why and will give you a good basis in the underlying engineering theory that will help you choose a boat that won't let you down offshore.
There was an age, not all that long ago in the grand scheme of things, when technological progress was a slow, measured affair. Revolutionary new developments in materials science, in hull design, in manufacturing processes and in many other engineering fields were few and far between. The "state of the art" progressed at a pace [...]
