The creator places his new sq. sail to the take a look at; it handed with flying colours!
Sq. sails have been used on crusing vessels for hundreds of years, and there’s little argument amongst square-rigger sailors that when the wind is coming from astern a sq. sail is a positive approach to propel a ship of any measurement, even at present.
Anybody with a Bermuda rig is aware of how tough it may be to maintain your sails full operating earlier than the wind, particularly in massive seas. It’s often essential to pole the sails out with an assortment of traces and preventers. Even then the particular person on the helm must maintain a eager eye on their course to forestall the sails from collapsing and refilling with a loud crack!
One other concern, particularly when operating with twin headsails poled out, is that they can’t be simply reefed. If situations change, the crew will inevitably must go ahead to cope with the state of affairs, most of the time at the very same time no one needs to take action. A triangular Bermuda headsail can be removed from one of the best form for holding the wind on a run, each by way of projected space and effectivity.
In contrast, with a sq. sail appropriately braced, these shenanigans merely disappear. Your heading can range broadly, by as a lot as 30 to 40 levels, as there’s little concern about broaching. The particular person on the helm or the autopilot may also have little problem sustaining a gentle course, and the boat will roll much less.

After all, the key drawback of a sq. sail is that whopping nice sheet of canvas billowing from an extended yard excessive up the mast: that and the attendant downside of unfurling and stowing, to not point out reefing the darn factor! This, in flip, precludes the usage of sq. sails on something however massive vessels with massive crews: like sail-training ships, aboard which you may have loads of younger folks keen and capable of scale the ratlines and edge out alongside flimsy footropes to reef or stow the flaying canvas—a harmful operation requiring harnesses and loads of coaching in even one of the best of circumstances.
Personally, I don’t have a crew of fifty aboard my Down East 45 schooner, Britannia, and my spouse adamantly refuses to scale any form of ratlines. (I can’t for the lifetime of me think about why!) Subsequently, if I wished a brigantine schooner with a yard for flying a sq. sail, I needed to invent a system whereby I might management the sail myself. The query was how finest to do that.
I had contemplated this downside ever since crusing aboard the Sir Winston Churchill, a square-rigged schooner run by the British Sail Coaching Affiliation. Since then, I’ve sailed on a number of different square-rigged vessels with quite a lot of different sailhandling preparations as nicely. One hauled the clews of the sail outward from both facet of the mast on a monitor alongside the yard, like drawing a set of curtains. When stowed the sail was brailed to the mast. One other hoisted the sail from on deck on the outermost ends of the yard and within the heart. Each these strategies labored positive when the sail was set. Nevertheless, each had critical drawbacks in that they might not be reefed. Dealing with the sails was additionally an “all arms on deck” operation, not in contrast to dealing with a big genoa or spinnaker.
I additionally as soon as checked out one other intricate methodology that employed an ordinary headsail roller-furling system mounted horizontally in entrance of the yard. This strategy allowed the sail to be unfurled, stowed and reefed from the cockpit. Nevertheless, the point-loads at both finish of the yard, the place the foil was connected, required a a lot heavier spar than if the sail had been mounted to the yard alongside its total size. Windage aloft was additionally elevated by the uncovered sail and furling drum, and the sail remained uncovered to the weather always.

Inspiration lastly dawned after I appeared on the comparatively latest idea of in-boom curler furling. That obtained me considering: why not use the identical concept to roll a sq. sail up and down inside its yard, like a curler blind? No one makes such a factor, so I set to work designing and making what may now be known as the “Hughes square-sail furling system.”
It took me practically two years and lots of fiddling, however Britannia now has a lovely sq. sail, or fore-course, in square-rigger parlance, flying from her foremast. (A “course” being the bottom athwartships sail flying from a given mast.) It has proved completely sensible for crusing downwind, and all furling and unfurling is completed from the protection of the cockpit. The sail might be lowered, stowed or reefed, in keeping with the wind power, by merely rolling it in or out of its hole yard. The load on the yard is evenly distributed alongside its size, and when utterly furled presents little further windage. When furled, the sail is protected against the weather and by no means will get moist, even in a downpour.
Constructing the yard
In square-sail terminology, the entire horizontal spar known as the yard. The sections outboard of the lifts are known as the yard arms, and every outermost finish known as “the Flemish horse.” In case you have ever been out on the finish of an extended swaying yard, even in a peaceful sea, you recognize why it’s known as a horse. In heavy climate, it may be like a bucking bronc! There isn’t a driving the Flemish horse aboard Britannia, although.
As step one to constructing my design, I needed to discover a sturdy 22ft-long aluminum tube with a slot operating its size. I did all kinds of net searches with out success, till it occurred to me that I might simply make the most of a part of a standard in-mast furling extrusion. Right here was an aluminum tube with a slot all the best way up. Why not simply minimize off the entrance part of the spar (which might add extreme weight and windage aloft) and use the remaining portion to each fly and stow my new sail?
Many sizes of in-mast furling extrusions can be found, and to search out the one that may work finest I wanted to search out out what diameter tube can be required to accommodate the sail. I did a sensible take a look at by merely winding a 19ft strip of sailcloth round a bit of tubing the identical diameter as the inner mandrel I deliberate to make use of to wind up the sail. This resulted in 20 turns of the mandrel and a completed diameter of 5in.

I telephoned a number of mast suppliers, who sounded shocked, if not a bit of nervous, after I requested, “How a lot would you like for a 22ft-long mast part?” (The extrusions I wanted are usually provided at three to 4 instances this size.) A lot of producers refused to promote me something after I informed them what I wished it for. However I lastly satisfied the gross sales supervisor at Charleston Spar in Charlotte, North Carolina, to promote me the fitting part on the proper value. As an additional advantage, I deliberate to manufacture the yard at my daughter’s printing works manufacturing unit in Hickory, North Carolina, a mere 50 miles from Charlotte, after which I’d take it to my residence port of Orlando, Florida.
With the lengthy tube within the manufacturing unit warehouse, I sawed off the entire entrance part utilizing a round noticed with a brand-new 60-tooth blade. That completed, I made some attachment lugs to hold the spar’s lifts, hoist, braces and fairleads, which a neighborhood man then welded on. I additionally hand-carved a few yard ends out of a pair of cedar blocks, that are detachable to supply entry to the mechanisms inside.
Along with the mast part, Charleston Spar was capable of present me with the identical mandrel and rope-operated winding drum the corporate makes use of in its mainsail furling techniques. After some shaping with an angle-grinder, I managed to suit the turning drum snuggly inside one finish of the tube, in such a approach that solely the furling-line sheaves are seen. Subsequent, I put in the 1in diameter aluminum mandrel (which features a slot to slip the sail in like in a furling foil): bolting one finish to the winding drum and the opposite to a big thrust-bearing and nut mounted on a thick endplate. The latter enabled the mandrel to be tensioned, to cut back sag. As a closing step, I painted my new yard darkish blue to match Britannia’s foremast.
Sail trials
Now that I had a yard, I wanted a sail. I didn’t wish to put money into an costly Dacron one, although, with out first discovering out whether or not the system I’d simply created really labored. I, due to this fact, minimize a form of take a look at sail out of an affordable plastic tarpaulin, which I purchased from a tenting store. This produced an efficient test-sail, although the truth that one facet was inexperienced and the opposite brown made Britannia look extra like Kon-Tiki than a contemporary schooner.
To forestall the leeches from bunching up contained in the yard, the sail was not in reality sq., however a trapezoid: 20ft vast on the head and 14ft vast on the foot. The autumn, or vertical dimension of the sail, was 19ft. When the sail rolls up contained in the yard, the leeches (the place the sail is thickest because of the edge folds)“barber poles” round itself in a form of a spiral, thereby avoiding any form of bunching.
With my take a look at sail connected to the mandrel and stowed contained in the yard, I used to be itching to strive it out in some wind. I had my eye on a big picket phone pole exterior the manufacturing unit, however my daughter rapidly put a damper on the concept. “You mustn’t try this, Dad, you’ll get me locked up!” she stated. (Although I nonetheless preserve there are not any precise ordinances in Hickory, North Carolina, forbidding anybody from hoisting a sq. sail up a phone pole!) In the long run I settled for hoisting the yard and sail on a set of pulleys up alongside one of many roof beams in my daughter’s manufacturing unit and used a pair of enormous electrical followers to supply the requisite wind. This labored tolerably nicely, and I used to be capable of roll the sail each up and down fairly simply.
Up to now, so good.
Subsequent up, I wanted a gooseneck to connect the yard to the mast. This needed to be sturdy and safe, but additionally removable, in case the sail jammed or within the occasion of an emergency. It additionally needed to pivot, in an effort to brace the yard to port or starboard when the wind was not useless astern. Lastly, it had be capable of rotate, so the yard may very well be canted when docked. It definitely can be asking for hassle to try to squeeze Britannia right into a normal-size slip with a 25ft spar protruding overhead. In the long run I used to be capable of fabricate a multidirectional gooseneck by modifying a spinnaker-pole connected to a traveler sliding on a monitor on the entrance of the mast.
Lastly, after months of part-time work on the undertaking, it was time to move the yard the 650 miles to Britannia, securely strapped to a picket framework on the roof of my minivan. As soon as there, to the good curiosity of my fellow yachtsmen, I hoisted my unusual contraption up Britannia’s foremast utilizing the middle hoist line, twin lifts and braces. It precipitated nice astonishment when a big brown sail instantly appeared out of the tube, then vanished inside once more with no single particular person touching it.
A couple of days later we set off onto the close by Intracoastal Waterway (ICW) in about 10 knots of wind to see how my new yard would do in the actual world. After turning Britannia downwind, I gingerly hauled on the “down” line, and my makeshift sail started to unfurl. Because the sheets got here in, Britannia slowly picked up velocity and was quickly making 4 knots. Zack, my 11-year-old grandson, requested if he might steer, not the kind of factor I’d usually entrust to a younger lad who had by no means helmed a sailboat earlier than. Positive sufficient, after I gave him the wheel he promptly started over-steering as landlubbers will. Nevertheless, my new sail remained full all through, making for a profitable first sea trial.
As destiny would have it, getting an precise Dacron sail constructed turned out to be a lot tougher than anticipated, as I couldn’t discover a sailmaker who had ever really made a sq. sail—by no means thoughts a sq. sail able to rolling up inside a 5in-diameter tube. Doyle Sails, in Stewart, Florida, confirmed probably the most curiosity, so I positioned my order there. In the middle of quite a lot of subsequent trials with my tarp sail, I had found the foot of the sail wanted to be straight, not concave like sq. sails I’d seen in photos. I additionally 1) included a batten into the foot of my new sail to forestall it from billowing out an excessive amount of and assist to maintain the sail straight when furling and a pair of) had it made with none built-in curvature, or draft, to ensure that it to roll up as easily as doable contained in the yard. When the sail arrived, it was time—finally!—for the ultimate stage of my grand experiment.

The day of reckoning
The breeze was splendid, 10 to fifteen knots straight down the ICW. We motored upwind for some time after which rotated. I minimize the engine and ready for the second of reality.
As a few crew tended every sheet, I hauled on the down line, and the sail started unwinding from contained in the yard. Because the wind caught the canvas, it started to unroll itself, however I managed it by slipping the “up” rope round a cleat and cautiously eased out extra sail till its total 340ft2 was billowing majestically earlier than us. The sheets had been winched residence, and I felt the boat collect velocity. Inside minutes there was a small wave below the bow as we coasted downwind at 5 knots. It was an awesome feeling to see my stunning white sail filling so nicely. Britannia didn’t roll in any respect. The movement felt extra like a catamaran than a monohull. It was so regular I felt no trepidation in steering straight by the slender hole below the mounted bridge we encountered a short time later. It appeared particularly slender now that my 14ft-wide yacht instantly wanted 25ft of clearance. As a speedboat overtook us, the folks aboard known as out, “Fabulous!” and “Nice present!”
Now got here the largest take a look at of all: rolling my new sq. sail easily again up into its yard. Though I had skilled occasional issues winding in my trial plastic sheet, I used to be pretty assured the issue stemmed from the flimsiness of the plastic materials and reasoned the a lot stiffer 8.5oz Dacron I used to be now flying would do higher. I definitely hoped so. You’ll be able to’t simply flip a sq. sail into the wind, which might make for a tough journey again residence. There was just one approach to discover out.
As my crew eased the sheets, spilling the wind, I wound the up rope round a winch and commenced hauling in. It was definitely tougher than unfurling, however the masses turned progressively lighter because the sail got here in, finally disappearing contained in the yard, clear as a whistle! Wow! One other milestone handed. Understanding the sail might be stowed or progressively reefed shall be an awesome reassurance when the wind pipes up.
Subsequent up was seeing how delicate the sail was to adjustments within the wind angle. Unfurling the sail, I steered a zigzag course, bracing the yard first to port after which starboard an excellent 30 levels. Amazingly the sail didn’t collapse till we reached an angle of round 34 levels on both jibe. It will permit loads of latitude when crusing downwind in following seas.
Within the months since I’ve had an opportunity to completely take a look at my new system at sea in all situations, and I couldn’t be happier. I’m even now planning to suit one other topsail, or “tops’l,” yard above the course, to hold one other, barely smaller sq. sail. Britannia will then fly over 500ft2 of athwartship canvas, which can add tremendously to boatspeed downwind. A mixture of two reefable sq. sails may also supply that a lot larger flexibility, in the identical approach a mix of sails aboard a ketch or yawl permits completely different sails to be set in keeping with the situations.
To make issues a bit of simpler, within the wake of my first few take a look at sails I additionally purchased a Winchrite electrical winch deal with (winchhandle.com) that effortlessly turns the furling winch twice as quick as by hand, a labor-saving system that can be utilized on Britannia’s different winches as nicely. By the way, the crimson cross on the sail is the English flag, which overlays a part of the Union Jack. It’s also the Templar’s Cross and the logo of the Crimson Cross Affiliation—all of which can solely add to the thriller of my little “tall ship” because it goes crusing by within the distance.
Earlier than having the actual factor made, the creator constructed a prototype sail out of a plastic tarp
TOTAL COST
General, the undertaking value $3,736. This consists of the price of subcontracted jobs, like welding. 4 items of kit alone represented about three-quarters of the full: the winding drum, $600; the yard and mandrel, $400; the gooseneck and monitor $380; and the sail $1,550. It’s tough to equate the price of this uncommon undertaking to the rest, i.e., to appraise whether or not it was costly or not. The closest equal would maybe be an in-boom furling system, with a 20ft increase at greater than twice the price of my yard—not together with the sail!
To try to work out the essential dimensions of each the yard and sail, I contacted a number of marine architects and sailmakers, however none was capable of inform me even how lengthy the yard ought to be, by no means thoughts what additional stresses the yard and sail would impose on the mast. In the long run, I discovered myself contacting the Previous Naval Dockyard in Chatham, England, in whose archives I discovered a method for yards and sails for a British frigate. I don’t have a crew of 300 to deal with the sails, however the method was all I needed to work with.
I used to be additionally involved about weight aloft. Early on I had calculated the theoretical weight of the sail and yard can be 135lb and was happy to search out that the precise weight of the sail contained in the spar was inside 5lb of my estimate. That is lower than the common weight of a person climbing the mast; nevertheless, the second of inertia can be larger, because the yard extends nicely past the boat’s roll heart. To be on the secure facet, I elevated the sizes off all of the foremast rigging, together with the 2 forestays and the triatic keep. I additionally beefed up the operating backstays for good measure.
Like most issues on a ship, it in the end comes all the way down to what you need and what you are ready to do when you can’t really purchase one thing ready-made. There have been instances after I was about to stop, and my household thought I used to be nuts anyway, which might be appropriate. Now, although, after I unfurl my stunning sail and see it billowing forth, I’m glad I persevered. My small square-rigger is actually distinctive.
