Day Sailer Operating and Rigging Instructions

CAUTION: DO NOT BEGIN OPERATING OR RIGGING YOUR BOAT UNTIL YOU HAVE READ ALL OF THE FOLLOWING OPERATING AND RIGGING INSTRUCTIONS THOROUGHLY.

Safety Information

The mast, the stays, and all other parts of O'Day sailboats under 26 feet, following the general boating industry practice, are not grounded. Should your O'Day sailboat be struck by lightning or make contact with electrical power lines, substantial injury may result to the occupants. We recommend that if you wish to be protected from an injury resulting from lightning, that you have your O'Day sailboat grounded by an authorized O'Day dealer or other reputable boat yard in the manner recommended by the American Boat and Yacht Council of New York, New York. Under all circumstances, whether or not your boat is grounded, when lightning is present in your boating area, contact with the mast, the stays, and other metallic objects should be avoided. We do not believe that grounding would be effective to avoid injury to occupants of your sailboat, if contact is made with electrical power lines. When operating your sailboat on waterways, charts should be regularly consulted, not only for normal hazards, but also for the presence of electrical power lines. In addition, a lookout should be maintained for the presence of overhead electrical power lines, particularly during launching and hauling.

The following is a list of standard equipment which comes with your boat.

1. A mast with two spreaders.

2. A boom with boom vang plate only.

3. Flat package containing rudder, tiller and boom crutch.

4. Sailbag containing mainsail and jib. The battens for the mainsail will be found in the sailbag.

5. Box of rigging containing main halyard jib halyard headstay, sidestays outhaul line, downhaul line, mainsheet spliced to single block with becket for mainsheet, jib sheet, boom vang assembly only less plate.

Suggested Equipment for Rigging Boat

You will need a medium sized screwdriver a pair of pliers, a small roll of tape to cover cottar pins.

Optional Equipment

See your dealer on what is available - comes complete with installation instructions where applicable.

Mast

The first step is to remove the two spreaders which are taped on to the mast. You will notice that these two aluminum tubes or spreaders have a hole in one end and a slot in the other end. These spreaders should be fastened with clevis pins on to the fittings on either side of the mast about one third up. Open ends of cotter pins after they are in place and tape. Into each of the slots place a sidestay. A small wire will be found in a hole at the slotted end of the spreader. Wrap the wire around the stay as many times as possible which prevents the stay from lumping out of the slot. This area should then be covered with tape to protect the mainsail. See fig. 1. Before you step the mast tie a figure 8 knot in the end of each halyard to prevent them from getting out of reach, and then pull the shackles on the other end of the halyards to the foot of the mast. This puts the shackles in reach when the mast is stepped.

Stepping the Mast

We recommend that you get assistance in stepping the mast until you are familiar with the stepping procedure. A "tabernacle" is a great help as it permits easy one person stepping. This is a slotted mast and the slot side faces the stern when in position to be stepped. The mast is stepped through an opening in the deck. Be sure the base of the mast is properly seated on mast step. Once accomplished, the mast will stay in place. Now fasten the sidestays to the chainplates on either side of the hull. Next fasten headstay to stemhead fitting. Turnbuckles, which permit adjustment, are provided on the lower ends of all stays See figs. 2 & 3. After all stays are attached, take the slack out of the rigging by tightening all stays taut, but no more than hand tight. If you find a stay too long or too short, check for proper length or possibly the mast step may have been positioned incorrectly. In the latter case, remove mast and then mast step. Next, step mast onto unattached mast step (be sure to hold mast at all times) and attach stays. When properly set up mark new position of mast step. Finally, unstep mast and screw step in place.

CAUTION: It is very important that you do not tighten the stays too much as this can cause damage to the hull.

CAUTION: Be sure all lock nuts are securely tightened by pliers or a wrench and then taped to prevent loosening. Attaching Boom To Mast Slip the gooseneck which is on the forward end of the boom into the slot on the mast and rest the other end in the boom crutch. See fig. 4.

Mainsheet

Attach the block to bail on the boom. Take the free end of the mainsheet, thread it through the upper sheave on the block on the aft end of the centerboard trunk, bring it up through the block on the boom then back down to the bottom sheave and thru the cam cleat. This type of mainsheet arrangement (as of January, 1974) frees up the cockpit considerably in that the lower end is attached to a stainless steel plate on the aft end of the centerboard trunk instead of the blocks on the port and starboard side of the stern of the boat. Tie a figure eight knot in the end of the mainsheet so you won't lose it. To Attach Rudder On the stern of the boat are two gudgeons into which are inserted the pintles on the rudder. The rudder blade will pivot back, should you hit an underwater object but the blade should be in the down position while sailing. If the blade works up while sailing, weather helm will increase thereby increasing drag and steering will become less efficient. Tighten the blade pivot bolt or wedge blade in down position. See fig. 5.

Centerboard

The fiberglass centerboard is held in the centerboard trunk with a stainless steel bolt on which it pivots. On the top of the centerboard there are two adjustment pendants, one running forward which exits at the forward end of the trunk and is used to raise the centerboard, and the second which exits on top of the forward end of the trunk and is used to lower the centerboard. *Watch these pendants for wear and replace when necessary by removing the centerboard bolt and lowering the centerboard out of the trunk. Cleat pendants to maintain proper centerboard position, except do not cleat aft pendant when sailing in shallow water. See fig. 6. *(As of August, 1975 a 10 1/2" piece of shock cord has been added to keep the forward c/b pendant tight while the c/b is down). Should the centerboard bolt leak it can be tightened if leaking still persists reseal with a substance like silicone sealant.

To Hoist or Raise Mainsail

To raise the mainsail, insert battens and then starting near the gooseneck, feed the foot of the sail, clew first into the slot on the boom. The pin in the gooseneck slips through the tack of the sail to hold it in place. Draw the foot of the sail out along the boom until the foot is tight. The outhaul line should be attached to the clew of the sail, then passed through hole in fitting on end of boom, then cleated on boom cleat which is located approximately two thirds of the way up on the right side of the boom. The cleat is located here to permit the crew to change the tension on the foot of the sail while sailing. A "block action outhaul" is a help here as it greatly reduces the friction on the outhaul line. Next, fasten the main halyard to the head of the mainsail and feed the luff of the sail into the mast slot cutout. Hoist the sail fully and cleat it. Tighten the luff of the sail by pulling down on the line attached to the gooseneck and then cleat it to the downhaul cleat. The position of this cleat on the mast may be changed by loosening the two screws, moving cleat, and then tightening screws again. See fig. 7.

To Hoist Jib

Fasten all the jib snaps on the luff of the jib to the headstay and attach fitting on the tack to the stemhead fitting. The jib halyard is then attached to the head of the jib just as the mainsail was. Tie the center of the jib sheet to the clew of the jib and run them aft on either side of the mast inside the stay wires, through the cam action cam cleats mounted on either side of the cockpit. Tie a figure 8 knot in the end of each sheet in order to prevent it from getting loose. See Figs. 8 & 9. The jib sheet cam action cam cleat on track is adjustable fore and aft positions it so that the tension on the foot and leech of the sail is about equal. Move lead forward to help stop leech flutter and aft to help stop foot flutter.

Outboard Motor

The transom is reinforced so an engine can be clamped directly to it on either side of rudder. We recommend a pad or transom plates which will prevent engine loss and scarring of fiberglass. Recommended horsepower, 8 maximum long shafts.

Roller Reefing

A "Roller Reefing Claw" is necessary. Your mainsail can be easily reefed, as the boat is equipped with a spring loaded gooseneck. First remove the block in the middle of the boom. Second, release the main halyard but keep it under tension. Third, pull the boom back from the mast so that you can turn it. Fourth, roll the boom either way as you or your crew lets off slowly on the halyard. The sail will roll on the boom. Fifth, when you have rolled about 5 or 6 times, you will have reduced your sail area by one third. Experience will teach you how much to reef under various conditions. Sixth, lock your boom back into place by letting the boom go forward and tighten up halyard. When reefed, the boom block for the mainsheet is attached to the roller reefing claw. To shake out, just reverse procedure. Flotation There is sufficient flotation material (in block form) located between the hull and deck to support the crew and normal gear, should the hull and deck compartment take on water through a leak or hull puncture. Be sure to check these areas prior to sailing and pump out any water. The Day Sailer cockpit is totally sealed and as long as it remains intact, no leaking should occur except possibly through inspection bailing hand hole covers in the cockpit floor or centerboard bolt. These can be easily resealed. A drain is provided in transom to drain any accumulated water from the lower bilge (under cockpit floor). This should only be opened while boat is beached or on trailer.

Self-bailer

Your boat is equipped with an automatic bailer located in the transom well. This enables spray or rainwater to be siphoned out while underway or at mooring with boat at rest. A check ball and rubber seal prevent water from entering while plunger is up in the open position. To open turn knurled knob counter clockwise. To close, reverse process

CAUTION undefined The DePersia bailer is of aluminum and the threads should be kept well lubricated to prevent corrosion. In salt water this should be done twice a season.

Capsizing Procedure

Should the boat capsize while sailing, there are a number of steps that should be taken to insure the safety of the boat and crew.

1. Make sure that each occupant has a life jacket on.

2. To prevent the boat from turning turtle (upside down), which can occur, put some weight on the centerboard which will help to right the boat.

3. Take down the sails, if sailing under severe conditions.

4. Bail out any water in cockpit.

5. Remember your boat is equipped with flotation material and it can act as a life preserver.

Boating Safety Act A new Federal Boating Safety Act was passed in 1971 to further encourage safety in boating O'Day endorses the general nature of this Act and certifies that it reasonably complies with requirements of the Act. There are several specific aspects of the Act new customers should understand.

1. Every O'Day boat has a special numbering system. Numbers are permanently molded into the transom on all models. The first three letters are our manufacturing serial number, the next letter represents the boat model code letter the first four numbers are the sail or class number and the last four digits represent the model year and the month the boat was built.

2. Customers are required to provide approved life saving devices for each crew member on board.

3. Availability of approved fire extinguishers is required on many boats. Customers should consider having an extinguisher even when not required.

4. Recommended horsepower for engine is included in O'Day's catalog and should be complied with for safety and warranty reasons.

5. After dark boats must be lit in an approved fashion undefined customers must make provision for this

6. O'Day is obligated to inform customers of manufacturing defects which may exist in specific boats. O'Day must describe the defect, evaluate the hazards involved, and state the action it is taking to eliminate the defect. Obviously O'Day cannot do this readily without record of each boat's owner, which is supplied by return of the Warranty Card. The Company strongly urges this Card be returned promptly. General

Information

The following information is to be used as a general guide and if you are unclear or need more help, do not hesitate to call upon us or our dealer. Tuning Do not over tighten stays as mainsheet tension will dictate tension on headstay While sailing, the leeward stays will always go slack due to mast bend, stretching, etc. , so under no circumstances should you tighten them under sail undefined all adjustments should be made while at rest with the sails down.

Maintenance

Fiberglass Repairs although fiberglass is a relatively simple material to work with, we urge that you familiarize yourself with the proper procedures in order to insure good results. The surface color (gel coat) should be cleaned and waxed at least twice a year in order to maintain its luster. The color may fade due to weathering and if ordinary cleaning will not bring the color back try a regular automotive compound followed up by waxing. Sails Dry and fold carefully after each use and if used on salt water, wash with fresh water every so often. Fold by stretching out the sail on the lawn or clear surface and starting at foot with person at clew and tack make one foot to two foot folds by bringing the head down toward you gradually and evenly. Finally fold from clew to tack or vice versa.

Preventive Maintenance

Be sure if you have a tabernacle, the screws and bolts are periodically checked. Woodwork - Varnish at least once a year using any good marine varnish. Teak can be either oiled or varnished. Bottom Paint recommended in both fresh and salt water. Follow directions on can be sure to paint centerboard as well as bottom. Leaking Should any leaks develop through hardware fastenings, hull and deck joints, etc., these can be easily fixed by applying a good marine sealant. Trailer Normally any good marine boat trailer is sufficient that will support the complete boat's weight plus say 20 percent which will cover weight of normal gear. A "trailing package" is a great help as it keeps mast and boom off the boat and makes tying down easier. For The Racer The rake of the mast can be changed by adjusting the headstay turnbuckle and then re-adjusting the sidestays. In general, a boat will perform better while sailing to windward with some aft rake and better downwind with the mast plumb or slightly raked forward. Races are usually won to weather, so favor more aft rake, if anything.

Sail Set the jib halyard should be taken up so that the tension on the luff while under sail is the same as on the headstay. The tension on the foot and luff of the mainsail should be such that there are no stress lines or wrinkles in the sail. Apply more tension as the wind increases, which will move the draft forward and decrease heeling moment, etc. In general, the outhaul should be slacked while sailing off the wind in order to create more draft in sail. Tell Tales are an invaluable aid in determining wind direction undefined 8 inch pieces of yarn tied to sidestays 2 ft to 4 ft up from chainplate and a wind pennant on top of mast. 6 inch to 8 inch pieces of yarn taped to luff of jib on both sides every 3 feet or so on bottom half of sail 8 inches back from luff wire are excellent wind flow guides. If you point too high, weather yarn flutters and if pointing too low, leeward yarn flutters. Both should flow back evenly undefined remember this only tells you flow pattern for a given jib trim, so trim must be correct for sailing angle.
