	Daggerboard - Wikipedia, the free encyclopedia
		A daggerboard is a type of centreboard used by various sailing craft.
		The shape of the daggerboard converts the forward motion into a windward lift, countering the leeward push of the sail.
		Daggerboards are usually found in small craft such as day sailers, where their size is easily handled by a single person.

	Rigging Small Sailboats - Chapter 10 (Site not responding. Last check: 2007-11-06)
		A daggerboard or centerboard is a thin vertical plate sticking out the bottom of the boat that gives the boat a "grip" on the water thereby preventing or at least minimizing leeward movement.
		While daggerboards and centerboards are not strictly a part of the rigging in terms of its "transmission" function, they do help greatly in converting the power of the wind in the sails to forward motion.
		One drawback of daggerboards is that should the boat sail into shallow waters or accidentally come up onto a beach, the daggerboard will not pivot back and up into the trunk as will a centerboard.

	Articles - Daggerboards
		Daggerboard catamarans have several advantages over their keel counterparts, some of which are well known and others that are more subtle and sometimes only recognized by people who have used them.
		Usually catamaran daggerboards have a higher aspect ratio and are deeper than the equivalent length monohull, since they have the ability to retract them and therefore have no draft considerations.
		Daggerboards, their surrounding structures and systems are more expensive to build, so builders prefer to stay away from them given the choice.

	Twin Rotating Foils on Multihulls/No Daggerboard - Boat Design Forums
		Banana boards are daggerboards that are curved so as to form a vertical lifting surface towards the bottom of the foil-not necessarily relevant to twin foils; they're used to partialy lift the boat.
		You could steer with either the rudders or the daggerboards, but he mosly envisioned being able to gybe set a positive angle of attack on the daggerboards, there were tillers and a cross arm with a comb.
		The daggerboards and rudders dropped through cylindrical cassettes, the only difference being that the cassettes were smaller than the 100% chord of the foil.

	RANT - leading edge of daggerboard trunk - The Laser Sailboat Forum (Site not responding. Last check: 2007-11-06)
		What I'm ranting about is how the daggerboard and trunk wear each other down due to the forward pull of the shockcord and the raising and lowering of the board.
		The problem with the daggerboard popping up an inch at every tack is now aggrevated even more than before with the high-standing camcleat fairleads on the new deck cleat base.
		The wear on the leading edge of the daggerboard and of its well causes the foil to rotate (trim forward) and does affect performance.

	Daggerboard sloop? - Boat Design Forums
		I have the opportunity to buy a 38 feet racing sloop, with a daggerboard (sliding up and down, not a pivoting centerboard) from which the deck has been repaced (!!!) from a flush deck to a cruiser/racer one.
		The daggerboard only weights 400 pounds but goes down 11', so there is no real weight down at the bottom.
		In a survival situation, with the daggerboard up, the boat will slide on the side (having very litlle "grip" in the water) so it's unlikely that the wind or sea will roll it over.

	ISCA CLASS RULES Amended March 1, 2003
		Anti-chafe material may be added in the daggerboard trunk solely to protect the construction and finish of the daggerboard.
		Any material may be added to the sides of the daggerboard trunk to improve the fit of the daggerboard.
		In the event of damage to hull, deck, daggerboard, rudder, mast or spars, necessary repairs may be made in a manner as close as possible to the methods and materials used by the Builder(s), and in such a way that the essential shape or other characteristics are not materially affected.

	Rigging Your Banshee
		The addition of a cam cleat for the main, preferably with a ratchet block, is essential to managing the boat in a blow.
		You should affix a layer of sponge rubber or thick carpet to the rear of the daggerboard well to protect the board’s trailing edge from crushing when you touch bottom.
		A piece of shock cord is provided which wraps around the daggerboard and well, and keeps the board in a raised position.

		Lateral resistance is provided by the fin, the daggerboard, and also by the underwater portion of the rail of the board.
		Turning a sailboard with a daggerboard relies more on the movement of the sail, than on the actions of your feet.
		A shortboard (without a daggerboard) turns more like a water-ski: as you tip the board with your feet, you turn.

	Learn About Optimist Blades (Foils, Rudder, Daggerboard)
		Because it is so technically difficult and labor intensive, only the most expensive daggerboards will be perfectly straight, most will have minor waves or a slight hook to one side, on the order of 2-5mm.
		In such cases, you may be better off with a less expensive blade as long as you pick a fair and straight daggerboard.
		As a coach, I often had very light sailors raise their daggerboard about a hand's width upwind in heavy air.

		I might use it later, but a kickup rudder bracket is available from Glen-L. This is where I got the gudgeon/pintle set for a small boat rudder used on my project.

	F-82 Daggerboard Rudder
		The drawings are now complete and available for the new F-82 daggerboard rudder.
		A daggerboard rudder can be deeper, offers better control, has less surface area, and the ability to lift rudder up for enjoyable shallow water sailing, without the heavy helm associated with kick up rudders.
		The traditional tiller is standard, a remote steering linkage to move tiller forward is optional.

		I built the daggerboard and its ballast component before the daggerboard case because then the case can be built to fit the board.
		Bulkheads, daggerboard case, and planking I chose marine-grade Okoume plywood for all bulkheads, the daggerboard case, and planking.
		Making the daggerboard case Once the daggerboard was completed, I built the daggerboard case wide enough to allow for clearance.

		The center of effort of your sail plan has to be slightly forward of the center of effort of the lateral resistance of the boat.
		The daggerboard is the main cause of lateral resistance.

	Sailing
		- Centerboard or Daggerboard designed boats are good because they allow you to sail in shallow water and can be pulled up for better performance when sailing with the wind behind you.
		Leeboards are designed for the same purpose but are fussier because they have to be changed with each tack.

		The crew was surprised to find late on Wednesday that the daggerboard, which optimises upwind performance, was damaged by the collision.
		The crew had to replace the damaged daggerboard, 4m high and weighing 700 kilograms, with the undamaged daggerboard from the other hull of the catamaran.

		Above and below: These are the first photos of the main hulls construction, gel coat,Tri axle glass cloth,windows and beam reinforcements and vac bagging the tomentoe foam on the sides of the hull.
		The daggerboard is origenal it is made of cedar wood with mohogany on the front and back edges to take the knocks and bumps, it was then routered out in the centre section and reinforced with 750g glass tape and epoxy resin and glassed with two layers of 75g cloth and epoxy resin.
		The daggerboard case was then moulded around the board with 2 slots on either side of the case, I found that the weight of the board sat in the case on it's own bouyancy and only pushed it down level with the deck when going to windwards.

		Most splits in the daggerboard well area usually occur along the trailing radius and the bottom of the hull.
		The hot air welder can be used to repair daggerboard wells, mast-steps, skeg boxes, and replace large hull sections that have been damaged.
		When replacing hull sections, mast-steps, and daggerboard wells, it is best to cut out the sections with 2-3" deep of foam attached.

	Re: Daggerboard Holder
		My FJ has 2 cross-wise thwarts, near the forward and aft end of the centerboard trunk (look for "Sliver", the wooden FJ with sail 4271 in photos from 2004 Eastern Regionals on the website, and maybe you can see it).
		The advantage of thwarts, is that the aft thwart makes a great seat for the crew in light air (sitting on a daggerboard trunk is uncomfortable, and it is harder to keep out of the way of mainsheet and vang when tacking).
		I believe that the old Vanguard I-FJs had a thwart at the aft end, and that in the front had some kind of combination thwart/knees/mast partner [??].
