What did a keel boat do?
Keel boats were and are used for transporting cargo, mainly inshore and on navigable rivers. They are powered barges in effect.
Why was the keel boat invented?
The keel boat was invented to provide stability and maneuverability to boats, especially in rough waters. The addition of a keel helps prevent capsizing and allows for better control over the boat's direction.
Who makes swing and retractable keel sailboats?
Two manufacturers of this type of boats are: Hake Yachts, 4550 SE Hampton Court, Stuart FL 34997 * (772) 287-3200 http://www.seawardyachts.com/ and Northshore Shipyard, Chichester Harbour U.K. http://www.northshore.co.uk
Can a 16 ft daysailer with a swing keel and a 6 ft beam and 21 ft mast tip over?
Yes, easily.
What is a flat plate keel?
In boats and ships, keel can refer to either of two parts: a structural element, or a hydrodynamic element. These parts overlap. As the laying down of the keel is the initial step in construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Only the ship's launching is considered more significant in its creation.
What figure of American folklore ran keel boats up and down the Ohio and Mississippi Rivers?

How far should your tiller rudder extend into the water for a 20' swing keel sloop?
There's no single right answer that will cover any 20' sloop, the size and shape of the keel the form of the hull and how the sails are ballanced will all affect what size rudder is needed, as well as the shape of it. Also the answer will depend on what handling characteristics are desired. As for just the depth of the rudder, usually it will go to slightly less depth than the keel when the keel is at it's deepest. Some lifting keel yachts, especially smaller ones, also have a lifting rudder.
How large of a sail boat can one person sail alone and what type of keel is best?
My father sails a 40 ft. sailboat, solo at times!Statistics have the majority of coastal solo-sailors in boats between 27 and 35 ft. However, with the advancements in sailing technology, several yachtsman are solo-racing boats to 60ft and some even larger.If you are considering a boat for yourself, I recommend you do a skills assessment, and step onto a few boats rigged for short-handed sailing, and see where you are comfortable.Good luck...happy sailing!As to the keel, I'm sort of a fan of wing keels in that they provide improved lateral resistance and yet don't draw as much. They also seem better able to withstand a grounding.It also depends on the type of boat if it is a cat then you can run lines back for solo and you usually have mini keels.Most sailboats have a swing not wing keel. Having a fixed keel makes beaching a boat very hard. Anyway on a trailer the fixed keel will be very high (The height of the boat AND the keel). With a swing keel JUST the height of the boat. Have fun and stay dry!Keels -- different approaches.My thinking goes like this:I don't expect to do a lot of portage personally, so highway transport of the boat isn't, for me, a factor. If it is for you, by all means include that into your calculations. I selected a wing keel in that the lateral resistance is quite high in ratio to the draft ... so you run less risk of unintentional grounding, and you can actually safely beach the boat on its keel under the right circumstances, although you wont be able to take up up on dry sand without an impressive tide.Two major factors, however, inform my selection. First is that dynamic or swing keels just aren't as strong as fixed keels. There's a movable joint involved, which weakens the keel, no matter how you work things out. On trailer, no problem. Far from land, however, and a loose or worse -- lost -- keel can be deadly, as it's VERY hard (and depending on the boat, potentially impossible) to sail without a keel. If you're a coaster and never far from shore, the risk is lessened. Blue water passages, however, are more risky.Second, it's difficult to add what I consider sufficient weight to a swing keel without making it unwieldy. Lower than ideal weight reduces righting moment, which in turn causes a cascade of unpleasant effects. Among these, knockdowns change from scary but usually harmless events to potential disasters, as the boat has a far greater chance of not righting. Also, you tend to heel more in higher winders, which makes for a wetter, more dangerous ride and the loss of a few points closer to weather that you can sail with deeper, heavier keels.So -- are you strictly weekending, trailering, coasting? Swing keels may be for you. However, if you're planning on being at sea for a while, rarely portaging, and doing more blue water passages, you might want to think harder about a fixed keel.
Who makes the largest swing keel sailboat?
The largest "swing" keel "production" yacht (ie. keel pivots/rotates into hull) is probably the Northshore Southerly 54rs. They have only just started construction, so if this does not count, then the next model down the 46rs is probably the biggest. Draught varies between 7 foot, to less than 3 foot with the keel up on the 46rs and it can be beached. In terms of "custom" designed yachts, the Bill Dixon Yacht Design Company have made a 100 foot yacht with a swing keel named Liara II (Liara II actually has a tubular keel, meaning the lower half of the keel with the bulb is lifted into the out keel casing. It works in the same way a telescope does. But large yachts can accommodate swing keels). Coincidently, Bill Dixon designed the (hull) Southerly 46rs as mentioned above. As for yachts with "lifting" keels (ie. keel moves vertically upwards) the biggest production may be the Hanse 630e which as the name suggest is 63 foot in lenght. Marten also producte a lifting keel yacht I belive. Wally have adjustable boards, as do products of many of the larger builders but it could be argued that these are custom, rather than production models as they all vary. As for custom yachts, adjsutable boards are fairly common, the biggest may be Mirabella V, her draught can vary between 32 feet and 13 feet. Mirabella V is 247 foot in lenght and set numerous records upon completion of construction in terms of size, sail area, mast height ect. The Southerly 57 is on the water at Southampton Boat Show and there is a 65 on the way.
Do you use a keel to determine a ships latitude?
A keel has nothing to do with the latitude.A keel does two things:structurally, it acts as the spine(or the breastbone) of the ship to tie the crosswise "ribs" together and provide strength.If the keel is seen on the outside of the hull as a fairly narrow ridge running fore-aft, it'll also help the boat stay on course. This is particularly important for sailing ships, for which the wind will try to push them sideways.Smaller yachts and sailboats can have a fin-like keel sticking straight down instead of a long ridge.Even smaller boats will have a daggerboard doing the same service
