HARBOR 20 TUNING GUIDE

Thank you for choosing North Sails for your Harbor 20. We hope using this tuning guide will help you get the most from your new North Sails. Our goal is to give you a rig set up that is fast in all conditions and easy to adjust. Some relatively minor modifications are necessary to the standard Harbor 20 layout in order to get the most from your boat and sails.

harbor 20 sailboat parts

Shroud Adjusters

It is important to have the proper shroud set up for effective rig tuning. Notice the picture above, the keeper allows you to make adjustments with the shroud locking mechanism so you can make adjustments to the rig based off the conditions.

The keeper and third hands will also prevent the shrouds from spinning off while sailing. These can be purchased in a variety of different rig shops.

Adjustable Backstay

In order to properly control the shape of the jib and mainsail it is a big help to have a easily adjustable and fairly powerful backstay. Making sure your backstay is running smoothly will allow you to de-power your sail in moderate wind conditions.

Mast Tuning

Before Sailing

First loosen shrouds until they are making 5” circles. From there tension the upper shrouds until they read 20 on the loose gage. From there fill your bucket half full of water and untie your stern from the dock so your boat is head to wind. Attach the bucket to the main halyard and let your boom sit on the cushions in the cockpit. Hang the bucket over the starboard side of the boat, and cleat the main halyard so the bucket handle sits flush with the bottom of the cap shroud. Then, without uncleating the main halyard, take the bucket and hang it over the port side of the boat. If the bucket handle is hitting the same part of the cap shroud on both sides, this means your mast is in the middle of the boat. If the handle is above the mark on the port side that means your mast is to starboard. If it is below the mark then the mast is leaning to port. Adjust the shroud to get the mast in the middle of the boat.

**Note:   it is important that the boat is faced into the wind. Likewise it is important that just one person is in the boat during this exercise, and that person sits in the same spot on both the port and starboard side. Do the exercise multiple times before making adjustments.**

After getting the mast in the middle of the boat, tension the lower shrouds to 10 on the loose gage. Sight the mast to make sure it is straight.

Now you should be ready to race! You should also sight the mast on both starboard and port to ensure the mast is symmetric side to side while under sail.

Light Air (0-8 knots)

Outhaul should be tensioned so their is about 3.5” between the boom and the foot of the sail.

Traveler should be centered. Never let your traveler go to leeward in any situations. There are folks in the fleet who actually screw their traveler to the deck so there is zero chance of it moving.

Tension jib halyard so that there is a hint of wrinkles in the luff.     Be careful not to over tension.     Adjust jib lead dependent on the jib.     If top telltales luff first, move the lead up on the clew board.     If bottom telltales luff first, move the lead down on the clew board.

Backstay should be adjusted so you have about 1.5” of forestay sag at base setting.

Moderate Air

Pull on the outhaul until there is 1.5” between the foot and the boom.     Tension mainsheet so top telltale flies 70% of time; top batten will be parallel to the boom.     This helps to generate power.     Tension main halyard/ cunningham to just remove horizontal wrinkles in luff. Use the main sheet to tension the headstay along with shroud adjustments. If you are easing main sheet, you are loosing headstay tension. Pull on backstay to help with headstay tension and to flatten the sails.

Trim sheet so sail is 2-3” from end of spreader.     Tension backstay to medium setting.     This will straighten headstay and slightly flatten sail Ideally you want zero sag in the headstay.

Outhaul out to band – max tight.     Tension halyard or cunningham hard to keep draft forward.     Tension lower shrouds to keep mast from bending too much.     Backstay on very tight.     Top batten should be outside of parallel.     Tension the vang tight enough so that the boom does not go up when the mainsheet is eased. This will allows you to “vang sheet” to keep boat on its feet.     Remember, flat is fast.     Play the mainsheet aggressively in the puffs to keep the boat flat.

Tighten halyard quite tight to keep draft forward.     Trim sail so it is 3-4” off end of spreader.     Tighten backstay very tight to make headstay as straight as possible and flatten sail.

*Please note that the above trim settings should be taken as starting points only.     These are meant to show the range of settings from light to heavy air.     We have found it useful to keep a logbook every time we go sailing to note fast settings or ideas.

About the Harbor 20

Built by the w. d. schock corporation.

www.wdschock.com

CLASSIC GOOD LOOKS – The W.D. Schock Corp. design team has deftly blended the beauty of traditional topsides with the efficiency of a high performance, modern rig and underbody to create an up-to-date day sailer. The graceful and distinctive lines of this Harbor 20 stand out in contrast to the many “look-alike” sloops on the market. The nice thing about classic is that it always looks right and never goes out of style. Modeled after the famous Herreshoff design, this new classic will turn heads in any harbor or yacht club, and provide each owner the permanent reward of a boat that’s always a pleasure to view.

COCKPIT COMFORT – The cockpit is where you live on a day sailer, and special attention has been devoted to maximizing this cockpit’s space, comfort and convenience. The seat and backrests are curved and angled to follow natural body contours. The two ice chests are within easy reach, secured by chocks and shaded by the cuddy. The seat lockers are cavernous, and the engine well doubles as an enclosed storage space. Small children are protected by the cuddy and the cockpit coaming, and there’s enough length and width to the seats to allow adults room to stretch out for a nap. Six plus adults, or the whole family can relax in comfort and electric motor can be easily deployed.

STABILITY & SINGLEHANDED EASE – By placing a significant amount (900 lbs.) of lead ballast down low, in a bulb, on a seaworthy hull, Shock has achieved an unusually steady craft with no bad habits. All lines are set up to lead to the cockpit so that one person can handle everything. The furling jib is self tacking and self vanging with the patented Hoyt Free Standing Boom. The fully battened mainsail is non flapping and powerful, and stacks itself safely between the lazy jacks. A special reefing set up allows one person to reef the main in less than 20 seconds – without leaving the cockpit. The Harbor 20 can handle a crowd comfortably – but it can also be a very satisfying single hander, so you don’t have to line up crew for what should be the simple matter of “going sailing.” These features are incorporated in one design class which is ideal for yacht club use because the need for skilled crew (or any crew) will be minimized.

PERFORMANCE UPWIND & DOWNWIND – You’d expect a modern sloop to sail well to windward, and the HARBOR 20 does not disappoint, pointing high and footing as fast as any similar sized day sailer on the market, without any need for hiking. This boat has a beautifully balanced feel that makes it pleasurably responsive and supremely easy to steer and maneuver. Downwind – where most sloops suffer the slows from non-functioning jibs – is where this boat comes alive. The jib boom keeps the jib out on all courses, and acts as an automatic whisker pole to wing out the jib. So while other jibs slat uselessly about off wind, the HARBOR 20 jib is an easily controlled, fully active drive unit on all courses – giving you full sail power, on all points of sail. You’ll be surprised how making the jib work full time adds to sailing pleasure and performance, and obviates any need for genoa or spinnaker.

TOP QUALITY CONSTRUCTION by W.D. Schock

For over 55 years the W.D Schock Corp. has set the standard for quality high performance sailboats. During their long history in the boat business, Schock has built over 70 different designs, including the Santanas Schocks, Thistles and numerous other popular one design sailboats. Like all Schock sailboats, the Harbor 20 is 100% hand laid up fiberglass and are engineered and built to yield maximum strength and rigidity. Their reputation for quality and service is well established.

A SMALLER BOAT THE WHOLE FAMILY CAN ENJOY – Today, most families can’t afford a large, one purpose racing boat that only one member really enjoys. And many older couples find they no longer need the trouble and expense of a large cruiser that sits idly at the mooring most of the summer for lack of crew. So here’s a boat that’s ready to go in minutes, suitable for one person or six, and it doesn’t require a major commitment of time or money. After all, the fun of sailing is more related to the ease and frequency of use than the size or expense of the boat. The Harbor 20 represents a new alternative, a classy day sailer that allows sailing to fit sensibly into modern lifestyles. Here is a boat whose stability and responsiveness will encourage you and your family to sail more often, and the One Design feature opens up simple, friendly, class competition on the race course. Safe enough to take along the kids, and simple enough to teach them to sail, the nimble Harbor 20 will please all ages.

LOA 20′ BEAM 7′ LWL DRAFT 3’6″ DISPL. 1800 LBS. BALLAST 900 LBS. SAIL AREA 232 S.F.

FEATURES AND BENEFITS OF THE HARBOR 20

Sailing Characteristics – The bow of the Harbor 20 has a fine entry for slicing through waves. The stern carries enough beam that the boat rides down waves nicely. The lead in the keel is concentrated in the lower half of the keel. The low center of gravity, with a 50% ballast-to-displacement ratio, combines with the ample beam to make an incredibly stiff and stable boat.

Construction – The hull is hand laid up mat and roving fiberglass. The resin is applied by brushes, rollers, and squeegees and is carried through hoses. Schock does not use a wet-out system, which sprays the resin into the fiberglass. They feel this system opens the door to potential osmotic blistering.

All bulkheads are tabbed into the hull for maximum strength. The bow is strengthened by a liner that is bonded to the hull on all surfaces. The bow structural support system includes an air tank, two bulkheads, and two platforms for ice chests. The keel grid is made of fiberglass and is bonded on all surfaces to the hull, spreading loads evenly. The keel grid incorporates two platforms for battery storage. This provides a place, both port and starboard, that is low and out to the sides, to strap down batteries, making the best use of their weight.

The hand laid up balsa-cored deck is bonded to the hull with a “shoebox” hull-to-deck joint. The deck is light and all one piece.

Cockpit – In the cockpit, at the forward end of each bench seat are two hatches that provide access to the batteries for the electrical system and extra storage. The cockpit floor holds three hatches to allow access to the sump, the electric bilge pump, the keel bolts, and the lifting eyes. The motor control panel for the electric motor is located halfway aft in the cockpit on the starboard side. This is the perfect location to reach the throttle while sitting at the tiller. The seat backs meet the seat bottoms, closing off the gap that is often found between the coaming and the seat. The seats are deep and wrap all the way around the aft section of the cockpit. The cockpit easily seats seven adults, while actually sailing . . . not just while tied to the dock. The aft lazarette contains the electric motor. The motor is mounted on an arm that rotates out and over the starboard gunwale. The deployment and retraction is assisted by blocks and line. Stowing the motor in this way keeps the prop from dragging in the water. The motor will push the Harbor 20 at about five knots without noise or smelly fumes. A charger is built into the cuddy on the port side. Just plug the boat in when done for the day. No more fuel docks, no noise, and no more rocking the boat when the wind dies.

Rig – The Harbor 20 rig comes with a roller furler for the jib, a Hoyt self-tacking jib boom, and lazy jacks for the main. The self-tacking jib makes single-handed sailing much easier, especially in tight quarters. It also allows for a much less experienced crew.

The sails that have been designed for the Harbor 20 are made of durable 6 oz. sailcloth. The main is equipped with full battens to further extend its life. The roller furling system on the jib and the lazy jacks make rigging and sail stowage a snap. Most owners leave their sails rigged and ready to go for the duration of the sailing season. Additionally, the lazy jacks prevent the boom and sails from falling all over everyone in the cockpit. When the sails can be put away so quickly, docking is amazingly easy.

The shrouds and stays are “Rigger’s Choice” 1 x 19, the highest quality stainless available. The running rigging is color-coded New England Rope Sta-Set. All hardware is Harken. The sail controls are led under deck to a shelf located on the aft edge of the cuddy and are labeled for easy identification. The contents of the shelf include the following: jib sheets, jib sock halyard, jib furling line, jib winger, jib outhaul, cunningham, main halyard, reef, and lazy jacks. Above the shelf is an 8:1 boom vang. The boom contains an internal outhaul. The backstay adjuster is lead under deck and into the cockpit. The mainsheet is adjusted from a cam swivel with a ratchet block located on a barney post. This leaves the access fore and aft in the cockpit clear. The traveler is located on the aft coaming of the cockpit. The mast is deck-stepped and can be equipped with a mast hinge. The rig is extremely simple, yet at the same time gives the trimmers a great deal of control over sail shape.

Strictly One-Design – When the Harbor 20 was used for the Championship of Champions, the competitors remarked over and over again that they had never competed in a round-robin with such undeniably equal boats. The competitors ranged in age from14 to 70. Class rules do not allow hiking, or even sitting on the rail. Greg Fisher, chairman of the event, called the Harbor 20 “a strict one-design that is both well balanced and simple to sail.” This places the emphasis on good boat handling and superior tactics rather than on athletic ability.

How the Harbor 20 came to be…..

On a beautiful Thursday evening about fifteen years ago, a group of seven salty sailors at the Newport Harbor Yacht Club in Southern California were sitting in the bar wondering why so few of the yacht club members were sailing. This got them to dreaming about the perfect boat. One that would get husbands and wives, families and friends back on the water.

After many more discussions on this topic, the salty seven came up with the perfect solution. A brand new 20-foot keel boat now known as the Harbor 20.

Each of the guys in the group had been an extremely competitive sailor in his day, but found himself sailing less each season. They had raced boats like the International 14, Star, Thistle, Etchells, Santana 20, Snipe, and Lido 14 but at 50+, they were no longer up to the physical requirements of these boats. And the hassle of racing larger boats had become a huge obstacle. The whole scenario of making twelve calls to get a crew of eight or nine together for a weekend race had definitely lost its appeal.

The more the guys talked, the more they realized how much they missed sailing and one-design racing. Surely there was a sailboat out there that could get the older sailors back on the water racing competitively and also get sailors of all ages out sailing with their families.

In the “good old days”, sailing had been a lifestyle. Generations of families had focused their summertime activities around yacht club events. But all of this had changed as dozens of new leisure-time activities emerged to divert their attention. The number of entries in the racing events was dwindling, and many of the boats in the boatyard sat idle for most of the year.

The group that met at the bar that day set out to change this. The man with the vision was Arthur Strock, a renowned architect with a passion for detail. He had a beautiful power boat but hadn’t entered a sailboat race in years. Recognizing that there were a lot of other sailors just like him, he set out to find a sailboat that would get Newport Harbor Yacht Club members back into sailing. He spent two years going from builder to builder, and he looked at daysailers and small racing sailboats all over the world.

In the end, he decided that the perfect boat simply did not exist. He kept detailed records of his search and compiled a 30-page document describing the boat that would be perfect for the job.

As Arthur did his homework, he continued to meet with the guys from that casual meeting at the bar. They were all staff commodores with outstanding racing credentials who definitely understood the importance of getting the members back into sailboats.

One of the members of that group was Tom Schock, past NHYC commodore, avid sailor, and owner of W. D. Schock Corp. Tom recognized the challenge faced by the yacht club, and he knew that it was a problem being faced by many other yacht clubs. He also knew that the future of sailing depended on finding new ways of making the sport more attractive. Junior programs were being enhanced to attract children to the sport, and exciting new high performance racing sailboats were being designed to entice young athletes, but nothing was being done to keep older sailors and busy young executives from abandoning the sport.

Based on Arthur’s study, the group zeroed in on the Criteria for their new design. They knew that the boat would need to be . . .

  • A beautiful, timeless design
  • Comfortable & efficient
  • Easy to sail whether sailing single-handed, double-handed, or with the whole family
  • Hassle-free
  • Fast & competitive
  • Fun for one-design racing
  • Perfect for daysailing with the family
  • And really easy to maintain

The Answer –The Harbor 20 – A 20-foot keel boat with a large cockpit and a self-tacking jib.

Another important member of the group was Steven Schock, a professional Engineer and Naval Architect with a lifetime of sailing experience. Steve designed the boat, focusing completely on the Criteria.

As a result, the Harbor 20 has a thoroughly modern and fast hull shape. The cockpit is huge. And the boat is equipped with things like cushions and the roller furling self-tacking Hoyt jib boom that makes it comfortable, efficient, and easy to sail.

The first Harbor 20 was launched in April of 1998. Within twelve years there were about 150 Harbor 20s sailing in Newport Beach. About 35 of these Harbor 20 owners actively race their boats, which means 115 Newport sailors love to daysail. Most of these daysailers join the class association so they can enjoy the parties, seminars, and lots of other special non-race sailing events. And the racers find the competition exciting enough to entice them onto the racecourse for Twilight racing five evenings a week during the spring and summer months.

There are now over 325 Harbor 20s sailing throughout the United States, Canada, Chile, and Australia. The Harbor 20 has definitely put families back on the water. It has also gotten husbands and wives back into the same boat. Young dads are racing with their children, and grandparents are sailing with their grandchildren. During this year’s annual Baldwin Cup Team Race at Newport Harbor Yacht Club, Jon Pinckney, one of Newport Harbor’s finest sailors, commented that “the Harbor 20 saved sailing at Newport. It has brought hundreds of sailors back into sailing.” Though certainly not in the 50+ category, Jon and his wife Gale are regulars on the Harbor 20 racecourse.

The boat is fun and easy to sail but definitely competitive. The design eliminates any advantage where crew weight and strength are concerned. Winning a Harbor 20 regatta depends entirely on the skill of the skipper. The Harbor 20 is perfect for teaching our children to sail. It is also perfect for taking friends for a delightful afternoon sail. All of the sail control lines are lead under deck to a console in the cockpit, so the lines are within easy reach for the skipper and crew. There isn’t a winch on the boat – there is no need for one.

The cockpit is 9 feet long, and you sit inside the cockpit – not on the deck. The boat comes equipped with two ice chests, and the class rules require that you race with cockpit cushions. It takes just five minutes to get the boat ready to sail. You just remove the cover and jib sock, raise the main, and unfurl the jib. At the end of the day, a clever custom-built electric motor will get you back to the dock. The motor pushes the boat along at about 4 knots. It is clean and quiet and is mounted on a special bracket that rotates out of the lazarette.

Plenty of options are provided to make the Harbor 20 fit any sailing style, and the boat is definitely easy maintenance. The Harbor 20s are generally kept in the water, and the only piece of wood is the tiller. The forepeak is a one-piece fiberglass liner. The floorboards, hatches, etc. are fiberglass. Even the floor timbers are fiberglass – no wood to decay over time. The keel is a fiberglass shell with lead and epoxy poured into the shell.

At the end of a day of sailing, you just roll up the jib, fold the main onto the boom, plug in the electrical power, and put the covers on. The boat sits ready and waiting for the next time you have a few minutes to spend sailing.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The Harbor 20 is a great alternative to the Lido 14 for beginning students who prefer the stability and comfort of a keelboat. The Harbor 20’s cockpit easily accommodates three students and an instructor and no one needs to sit on the rail to balance the boat, or duck under the boom when tacking. Deep coamings provide comfortable back support.

All halyards and lines are let below the deck where they lead to hardware mounted on a shelf at the aft edge of the cuddy cabin. This design keeps everyone in the cockpit, the deck clean, simplifies sail control, and allows sailing to become second nature.

The Harbor 20 was designed with simplicity in mind and a competitive spirit at heart, whether you’re sailing upwind or downwind.

  The Lido 14 Sailboat

The Lido 14 sailboat is exclusively manufactured by W.D. Schock Corp. 

Lido 14 history begins with Barney Lehman, boat builder and designer. Barney, best known for his Lehman series of dinghies, had been in development of a 14 foot version of his successful Lehman 10 when he sold his business to W.D. "Bill" Schock. Bill, a successful small boat builder, completed the work that Barney had started by creating a fractional sloop rig, increasing the boat's beam for stability, adding internal seat tanks for comfort and buoyancy, and providing a foredeck and a deck stepped rig rather than the Lehman's traditional keel stepping.

The year was 1958 and the location was Newport Beach, California. Newport Beach is one of the sailing centers of the nation, due primarily to the mild weather and the extensive sailing environs of Newport Bay. The bay, naturally created by the void between coastal bluff and a peninsula running along the Pacific Coast, was originally nothing more than sandbars and silt from estuaries. Dredging and development led to a navigable harbor containing eight islands, thirteen yacht clubs and boating associations, thousands of "cottages" large and small, nearly an equal number of boats, and 26 miles of shoreline. It is an ideal location for family sailing and served as the impetus to build a simple, fun, and comfortable sailing dinghy.

What followed is nothing short of spectacular. Within three short years, almost 1000 boats had been built. By 1970, with the total approaching 3000. Of these, a very large percentage involved in competitive racing around the nation. It was common for relatively minor regattas to have 60 or more boat and major regattas having limits of 100. As with all one-design boats of the era, the popularity of the Lido 14 peaked in the mid-70's. By 1980, the total number of boats constructed had risen to nearly 5000 but the number of new boats was quickly decreasing. A testament to the quality of the construction is that boats built in 1960 are still actively racing and will continue to sail many years to come given a little maintenance and loving care. Perhaps to the chagrin of W.D. Schock Corp., the availability of quality used boats sustains the popularity of the Lido 14, providing an unmatched entry into the wonderful world of small boat sailing! Reference: Lido14.0rg

    A fine entry with firm bilges and a long run aft give the Harbor 20 high speed potential, high stability and the ability to move smoothly through choppy water. The rudder is placed well aft, and the 900 lb. bulb keel keeps the weight low. This keel design gives the boat plenty of stability without slowing the boat down in light air.

  5. The Harbor 20

    The Harbor 20 was designed with simplicity in mind and a competitive spirit at heart, whether you're sailing upwind or downwind. For example, a roller-furling fractional headsail and self-tacking club boom help the Harbor 20 practically sail itself upwind. When running wing-and-wing, the club boom acts as a vang, effortlessly holding out the jib.
