We start the book with the comparison of a cruising sailboat under power to a typical trawler. After all, we sailors don't want to take a step backward in efficiency and speed as we transition to power. The surprise is that, in many cases, that's exactly what will happen.
Better Offshore Motorboats
Let’s face it, most of us offshore sailors have thought about transitioning to a power boat at some time, even if only as a way to stay on the water as we age. In this book we look at the issues and options for a sailor’s offshore power boat.
And even if you are a died in the wool powerboater who has never sailed, you will find a new way to look at offshore powerboats within these pages.

In the last chapter we compared sailboats and trawlers. In this one we look at the design parameters that if exploited properly could result in a better motorboat.
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 Matt's insightful analysis of hull form and cost considerations.
So far in this online book we have looked at the technical and performance aspects of offshore motorboats, but what's it really like to make a passage on a trawler? John and Phyllis report on a crossing of the Gulf of Maine in a Nordhavn 55.
In this chapter, we discussed what Phyllis and I have learned about motorboats and particularly our impressions as filtered through our experience of tens of thousands of offshore miles in sailboats.
We look at seaworthiness, fuel burn and my thinking on the related environmental issues, and then finish up with what all of this means to Phyllis and me personally.
I have written quite a bit about sailor's motorboats and as part of that project we analyzed a very interesting boat in-build in New Zealand. That boat, the Artnautica 58, has now been launched and is in the middle of sea-trials with encouraging results. It's too early in the testing process to draw firm conclusions, particularly since [...]
Offshore motorboats could be safer, faster, and much, much, more fuel efficient. John looks at how, and some innovative boats that are making that happen.
Four Artnautica LRC 58s are already launched or in build. Here are some new storm survival and layout options based on John and Phyllis' decades of living on and sailing an expedition sailboat.
When designing an offshore motorboat one of the first decisions we must make is what we intend to do if the main engine fails far from land or help. John takes a deep dive into this complex issue.
There are benefits and drawbacks to all get-home backup power options for offshore motorboats, which makes this vital decision surprisingly difficult. John shines a bright light on the tradeoffs of each option.
In the last two chapters we looked at whether we even need a get-home option for an offshore motorboat and concluded we do, so we looked at six options. In this chapter John reveals his winner, and why.
