    The Genoa sail originated from that port in the middle ages and was originally a single equilateral triangle attached at the foot to the bow , the peak (head) then taken to the masthead by a rope called a halliard , and the clew ; = the corner where the controlling sheet rope is tied on , secured to the quarter (one side of the ship's back-end ) = the stern .

    Used on the single masted small trading ships of the 1400s it was a powerful sail , good on all points of sailing except downwind , where it needed booming out ( a spar attached to the corner where the sheet was attached to hold it out sideways ) .

    It was rather a " man-killer " when you came to tack however , as the sheet had to be taken forward and around the mast .

    Used again during the late 1800s on big racing yachts because of it's splendid driving power , as with many racing fashions it became a standard feature of cruising yacht's rig , where damn-fool owners thought it made them look modern , fashionable , smart and sporty .

    As many smaller family cruising boats are crewed by just Mum and Dad however , its size and unhandiness when tacking make it hard work and often positively hazardous when compared with a twin headsail rig .

    Also the constant rubbing of the sail against the wire rigging is only good news for the sailmakers .

    The word Jib has now come to mean any triangular sail set in front of the mast , but this is technically incorrect . the sail most people call a jib is in fact a fore-staysail , being hanked onto the forestay , and filling the triangle between that and the mast .

    In a twin headsail rig the jib is set further forward than the staysail , often to a bowsprit .

    If the staysail is made self-tacking ( i.e. a small spar is set along the foot of the sail which is sheeted down onto a sliding track , so that it requires no handling at all when tacking ) then Mum is left to handle only the jibsheets , on a sail a third to a quarter the size of the genoa ; - much easier and much safer !

    And if the wind gets up and you have to reduce sail , then you simply drop the jib altogether , leaving the staysail up to draw .

    Because of this difference in weather conditions usage , staysails are usually made in heavier sail cloth and cut less full ( = less baggy ) than the jib .

    Technically the twin headsail and mainsail rig is a cutter , while the single headsail and mainsail is a sloop rig .

    Of course the single headsail rig cannot possibly suit very many different wind conditions , therefore requiring the changing the headsail to suit the conditions ; many long distance boats might carry as many as five in various sizes and weights of sailcloth , viz - Storm-jib ( or spitfire ) ; Working jib ; Cruising Jib ( or no1 Genoa ) ; no2 Genoa (previously called a Yankee ) ; and cruising Chute ( previously known as a balloon jib ) .

    Pity poor mum , sent to wrestle with those on the foredeck .

    Forestay roller reefing headsails ameliorate the problem somewhat , but you still have a compromise in sailcloth weight , which generally means the fully extended sail is marginally too heavy for efficient " ghosting " in light airs , while the close-reefed remnant triangle is far too light and baggy for anything like heavier weather .

    Plus , God help you if you get caught out in a blow and the thing unwraps , or the roller gear snags .

    Genoa - headsail of greater than 100% the mainsail area when hard sheeted the clew is astern of the mast at least. Bermudan rig very powerful upwind, typically 130% of main, can be much larger. normally mast head rig. Yankee - high footed head sail. Seen on schooners and cutters that may have multiple head sails and jibs. May be three quarter rig. Offshore sail brilliant for reaching. Mizzen - generally smaller sail cut similar to the main mounted to mast and boom mounted to stern of boat. Typical Ketch rig has these - with a genoa and mizzen only a yacht is self steering so beloved in the cruising community. Stay sail - smaller headsail hanked to Jack stay (about half way between mast and forestay.) storm conditions or additional power inside head sail. Spinnaker, large unstayed sail streamed ahead of boat down wind or on a shy reach, prodded out with a pole, some are cut like an immense headsail and used on reaching for planing type hulls. Mostly streamed from the masthead.

    A jib is a generic term for a triangular foresail. A genoa is a particular kind of fairly large jib that overlaps the main mast.

    1. The numbers that come on a sail with the boat tell what model it is and the order in which it came out of the mold. Boats are not purchased or registered at the time these numbers are put on, though it's certainly possible a club could change this themselves. 2. There are numerous differences in sailboats. Mono hulls have one hull, catamarans two, trimarans, three. Sloops have a certain rig with one mast, ketches and yawls have 2 masts. A dingy has a centerboard which is not ballasted. Keel boats have weight in the keel to help keep the boat upright. One could go on.. 3 There are hundreds if not thousands or uniquely named parts to a sailboat. I'm sure a simple google search will bring up a schematic with many of them labeled. Some parts that come to mind: Stern, Bow, Mast, Boom, fore stay, side stays, back stays, spreaders, chain plates, tabernacle, boom vang, cunningham, main sheet, mainsail, foresail, jib sheets, main halyard, jib halyard, roller furling, lazy-jacks, sail cover, down haul, out haul, shackles, fair leed blocks, traveler, cockpit, grab rail, toe rail, scuppers, life lines, bow pulpit, stern pulpit, companionway, galley, salon, birth, settee, anchor, rode, windless, winch, binnacle, helm, tiller, wheel, lazarette, through-hulls, sea cocks, head, holding tank, fuel tank, water tank, deck fills, transom, keel, centerboard, bilge, bilge pump, deck, foredeck, hatch, nav. lights, steaming light, anchor light, engine, propeller, propellar shaft, stuffing box, engine bed. Each sail has a foot leach, luff, head, tack and clew. Again, one could go on and on...

    A Genoa sail was the invention of the pirates in the Mediterranean... it was really maneuverable. A jib is more of a ridged steering sail.

    I'd imagine they'd have pictures of them on the Net.
