Deck Arches

QUIDNON has a large, flush deck, unencumbered by cabin tops, hand rails, vents and various other features that often makes sailboat decks far less useful. It can be used for lounging around in a chaise-longue or a hammock, for stacking bales of hay or cords of firewood, or for mounting various bits of equipment, such as plastic incinerators, digesters that produce gas for cooking or for running the engine, and biochar kilns. It can even be used to keep a few cages of chickens (for eggs and meat) and some small livestock (goats, for milk) tethered to the foremast. It is covered with aluminum diamond plate, for good traction, excellent wear resistance and to keep the boat cool by reflecting most of the sunlight.


The large expanse of QUIDNON's deck (measuring close to 550 square feet) is interrupted by two masts stepped in mast tabernacles, a large hatch in the center of the deck, and the dodger and cockpit aft. These elements are quite traditional; but there are also two more elements that are somewhat peculiar: there are two deck arches. They bear resemblance to boom gallows, but they are much more than that. In keeping with QUIDNON's overall design philosophy, they fulfill as many different functions as possible, to save space and to minimize costs.

The two deck arches are made up of three joined box sections—two feet and the arch itself—cold-molded out of plywood and fiberglassed on the outside. A thick plywood baffle runs along the centerline of the entire structure, to give it strength and to separate the airflows on the two sides. Along the front and the back of the arch there are openings, which can be closed and secured shut using internal sliders. On the bottom of each arch, in the center, is an eyelet for connecting a hoist. Where the arch joins the feet, there are diagonal reinforcements. At the tops of the arches are perforated aluminum angles (not shown) which can be used to attach an awning.

The arches serve the following functions:

1. Provide a point of attachment for a hoist. The front arch is used to hoist objects in and out of the cabin through the large mid-deck hatch. The aft arch is used to lift the engine out of the engine well.



2. Provide attachment points for the hammock or a swinging bench. This is an additional function of the two diagonal reinforcements in the inside corners.



3. Provide attachment points for an awning. The upper edges of the arches carry perforated aluminum angles.

4. Provide ventilation for the cabin. Front and rear sides of both arches have openings that let air either in or out, depending on wind direction. A baffle along the centerline of each arch keeps the two airflows separate until they reach the cabin, where they terminate in vents that direct the airflows in different directions, blowing air in and also sucking it out. They provide plenty of ventilation at anchor and on all points of sail except a beam reach. When sailing a beam reach in relatively calm conditions, the mid-deck hatch can be cracked on one side to cool the cabin.

5. Provide extra buoyancy up top in case of a capsize. The air openings on the front and back of each arch can be closed and secured using sliders, to create an airtight structure above deck level. Each arch encapsulates around 15 cubic feet of air. Both arches add around 2 tons of positive buoyancy 4 feet above deck level. This is very useful in case of a capsize, and enough to prevent QUIDNON, with its large, flat deck, from wallowing upside-down for any length of time.

6. Provide attachment points for sheet blocks (on top of each arch). A known problem with junk sails is that with most sheeting arrangements the sail tends to twist, losing efficiency, especially to windward. What typically happens is shown on the left; the optimal arrangement is what's shown on the right.



But in many cases this doesn't matter. For those who want to use QUIDNON primarily as a houseboat and prefer to keep things simple, a very simple sheeting arrangement will work fine, with a set of blocks mounted on top of each deck arch, while those who will want to make long passages to windward and would like an extra bit of speed can add a euphroe. I am also playing around with ideas for the ultimate solution: an automatic sheet traveler, but haven't tested it out yet. Here it is, shown schematically—not drawn to scale, and the final design will use tracks, sliders and blocks rather than rods and rings. But if you think hard enough, you should be able to puzzle out how it's supposed to work.


7. Provide places to mount navigation lights, red/green on the sides of the front arch, white aft light in the center, on the back of the rear arch.

8. Serve as boom gallows. When the sails are down, they can be made to rest on top of the arches.

9. Provide a support structure for the masts when they are down, for motoring down canals.

10. Provide an elevated place to sit or stand, to see a bit farther on the horizon and to be able to read the water better when sailing through shallows.

General progress update: There is now a full 3D model with most of the features drawn to scale, done in Sketchup. It has been moved to make a model in Delftship, which will be used for various calculations, and is in the process of being imported into SolidWorks, for creating a 1:12 scale model. There are plans to set up the model with radio control and sails, and to see how well QUIDNON sails.

Triumph at the End of a Rocky Road


The note above shows one of a rapidly growing list that Carol B has received from family members after privately publishing a volume of family history laced together with relevant aspects of her personal story. She swells with happiness at each one. These notes are more than usually rewarding. The road to this outcome has been rocky. Her stories sizzle with intrigue. That eventually presented a problem.

Carol, her parents, and a family friend (I omit her full name at her request to protect her family’s privacy), spent decades gathering stories and documents from county records and other sources, documenting purchase and sale of property, births, deaths and marriages, police and jail records, newspaper articles and pictures. Piles and piles of pictures. She took careful notes as relatives chewed the fat at family events.  She even sought out help from her local historical society to gather added information.

Eventually she wove memories and facts into stories. Lifestory writing group members pointed out unclear areas, missing material and more. Her strong writing grew polished in both content and structure. Then forces of darkness emerged.

Her family’s history includes mayhem, madness and murder. It’s all a matter of public record, and mostly forgotten, though ripples remain in family attitudes and traits. Still, she was loathe to publish it all without warning the family. She told everyone whose names appeared in the book what she was up to and asked their permission to share stories relevant to their immediate family members. With the exception of one person within her family, she was offered nothing but support and encouragement.  She did not have anyone else read her book, as she was not willing to write a book by committee.  As it turned out, the faith that family members had in her was almost unanimous. Others showed their trust by giving full permission to use their names and their particular family stories.

However, there was one family member who, without even reading the book, objected on principle. “There is no reason to dig all that stuff up again.”  Said Person would not discuss it with Carol and did not respond to numerous requests to be named in the book, then cut off  direct communication.

Carol’s inner critic went nuts. What if I’m sued?  Maybe I’m too critical. Maybe my book is too negative.  Even if I do expose the people in my book to public scrutiny, these are the stories of my family. What should I do?

Her voice had the sound of defeat as she told me, “That person has gobs of money and can afford to sue me on a whim. Maybe that will happen. Maybe I should just drop it. Maybe I should just share the Word file with anyone who wants to read it.”

“You’ve told dozens of people you’re doing this, and they all want to see it finished. What about them? Will you be letting them down? You’ve set aside funds to see it through. How can we work around this?”

Note to readers: don’t try to handle this alone. Get plenty of perspectives. 

“Do you think I’ve been too critical?  Is my book too negative?”

“NO! But I’m not always the best judge of emotional tone. Let’s get one more opinion.” I recommended another writer I know who excels in this area. Her response was supportive. Carol regained her grip.

She decided she would proceed with the project with these caveats:
  • She omitted all references to Said Person beyond a couple of picture captions where she cites the relationship without a name.  She decides to include a vintage photo of Said Person, but includes only a first initial and maiden last name.  To do otherwise would have made her uncomfortable, since she did not want to purposefully leave anyone out of the family history.  She also decided to mail Said Person a copy of the family history book. To date, there has been no acknowledgement of receipt though communication on other subjects has been resumed. 
  • In the Acknowledgments she states: “I have remained faithful to the stories that were passed down through the family and relied on my own memories and those of other family members for additional tales. Throughout the process, I maintained my belief and intention to cause no harm.”
  • The back cover includes a disclaimer of sorts: “… For decades she has collected stories from relatives and public records. She compiles those stories with personal reflections to tell the family’s story with truth and honesty to the best of her understanding.” 

She also firmed up her decision to keep publication as private as possible.

This last step required thinking out of the box. Carol is facing serious health problems and wants to ensure that her extended family will be able to independently order additional copies for years to come.

In line with her decision to keep the book private, she vowed to avoid all promotion and publicity. She is eager, however, for others to know of her experience, even though they won’t be reading the book. Buoyed by the outpouring of gratitude from family members, such as the note above, she has asked me to share that story, hoping to inspire others who battled doubts about sensitive disclosure to persist and find their own way around obstacles.

I’m happy to oblige, emphasizing to readers that publishing privately with limited distribution can be a strong and rewarding option for those who shy away from telling all to the world at large.

As the fan letter notes, Carol is hard at work on a second volume, a personal memoir. Will this one also be kept under wraps? Who knows? If she opts for open publication, you’ll be among the first to know.
