Sharpies are a rugged-type sailboat with a flat bottom, a very shallow draft, centered and straight, combustion side. They are believed to have originated in New Haven, the Connecticut region of Long Island Sound, USA. They are traditional fishing boats used for oysters, and then appear in other areas. With centerboards and their shallow balanced steering wheel is perfect for sailing in shallow tidal waters.

Sharpies New Haven
The first Sharpies became popular in New Haven, Connecticut, towards the end of the 19th century. They began to be used instead of wooden log ships and most likely came from sailboats. In the 1879 edition of Forest and Stream, a man named Goodsell claimed to have built his first Sharpie with his brother in 1848 and his claim was never contested. Sharpie is usually used to boil oysters and evolve to fit the job. They are getting popular because it's easy on the line, cheap to make, and fast under the screen.
Varies in length, the one-man craft of 24-28 feet usually has one screen, while the larger two-person boat that is about 35 feet is rigged with two screens, as cat-ketch. They have a leg-o-mutton screen with sprit blast on unkempt poles. Larger boats have three steps; one in the bow, one in the middle of the ship and one in between. Usually, in the summer, two poles will be trodden: one on the bow and in the middle of the ship. In winter, when a heavier wind is expected, a pole will be trampled. Their hulls are narrow with large and low freeboard. At the end you will find an upright arc with the heel of the rod sitting out of the water and a stern round. The long and shallow centerboard is like a balanced steering wheel.
Migration
The Sharpie type migrates south and west to other areas where shallow water prevents deep ships from operating, including Chesapeake Bay, Carolina, the Great Lakes (Ohio) and Florida.
Although most sharpening tools are rigged as foot-o-mutton foot paints with free-standing pole and sprit boom, larger versions - especially those found in Carolinas and Florida - use a fixed gaff schooner that includes jib.
Further developments and variations
Sharpies was introduced to Florida in 1881, when Commodore Ralph Munroe brought a 33-foot New Haven style sharpie, from his own design, Kingfish to Miami Florida area. Perhaps the most famous of the Sharpies is Commodore Egret design, now immortalized in the plan available from WoodenBoat magazine. Commodore Monroe designed Egret in 1886 and built it on Staten Island and sent to Key West.
Egret is unique because it has a higher and larger side than typical and double-ended. This means more stability as it loads and the ability to run in front of the ocean without waves splitting the stern. These attributes contribute to the behavior that causes the Commodore to call Egret a "sharpie-lifeboat".
Throughout the late 19th century, Commodore and others helped to develop this type. A variety of sharp yachts are designed by those who find interesting sharp lines. Thomas Clapham used the v-bottom in his "Nonpareil sharpies", and Larry Huntington introduced a curved bottom, which has been used by modern designers such as Bruce Kirby and Reuel Parker. Some people believe that the Chesapeake Bay chakra with its v-bottom may have evolved from an early spur. Whatever the case, the sharp Chesapeake boats are common, especially in smaller sizes, because of the easy and inexpensive construction.
Howard I. Chapelle, a naval architect and maritime history curator, writes several books on traditional boat work and shipbuilding, some of which include sharpen design and construction. He is a supporter of the pleasure boat based on a working boat model and designs many sharp sailboats, cruisers and cruise ships. For a typical example of his work, see the article on 14-foot sharp.

Modern sharpies
In recent years, sharpie, like many traditional American crafts, has enjoyed a renewed interest when designers and seafarers have searched for boats with superficial design and ease of construction. However, most are self-built or disposable construction. Exceptions include a series of Norwalk Islands, Bruce Kirby Islands, Catbird 24 by Chesapeake Marine design, Johns Sharpie by Chesapeake Light Craft, Ted Brewer's Mystic Sharpie, various designs by Parker Marine, and Phil Bolger's unique design.
Design considerations
As with any story, sharpie is at first gentle because they have a shallow draft without paying off. They need large quantities of ballasts stored on the central floor before they are accepted as ships: 600 to 900 pounds is normal in a 30 foot boat. Sharpies rely on high topside and light up to provide stability when leaning on range or upward wind. Unstable twin masts make rigging very easy and cost saving. An unstable bending column also allows spill winds from the screen to help with stability. The flat bottom, narrow water line and a work screen that simply means a fast boat down the wind where the flat bottom helps promote surfing or plan in stronger winds. Narrow beams, high center of gravity, low aspect ratio of middle board and longitudinal steering form do not help the wind performance, but most of these same features help in shallow water or where boats should frequently change direction, such as in tidal or rocky estuaries. Sharpies cabin is a sense acquired due to the space taken by a large central centerboard case and limited headroom. Even the traditional tapered 30 feet tall fit only for a maximum of 2 people while sailing for a week. A sharpie does not have a strong self-righting ability from a more conventional marine cruiser, making it best suited for sheltered waters. It takes an experienced captain who understands design flaws.
Newly developed Sharpie style hulls in New Zealand are made of plywood, using a water ballast in an empty bottom tank when a trailer, vertical (dagger) ballast board (about 80-100 Ã, Â £) type of centerboards (hoisted with 4: 1 block arrangement simple) is brought back to the cockpit) and usually around 20-24 feet LOA. They are not traditionally rigged, instead of having a conventional sloop fractional rig. They experienced a brief period of popularity in the 1980s and 1990s.
Designers such as Ian Oughtred have produced a modern version that incorporates many traditional features while overcoming some weaknesses, especially shallow, balanced steering (which has a tendency to lead to wild and erratic steering in the great ocean) with more transom-hung spinning axle blades conventional. The Haiku design also has a completely destroyed screen in an attempt to improve wind performance. Oughtred offers Haiku with one twin-swinged centreboard, which provides more interior space, at the expense of hydrodynamic efficiency, or a single central board, which takes up more space. At 30 feet long the Haiku is set up for small families to sail in sheltered waters.
Phil Bolger devised an incomplete solution to the hull problem of the ship at anchor, which affected the flat bottom ship, by making a 3-foot-long, oval-shaped anti-skid sheath with multiple layers of about 2 inches, then rounded to a shallow bow. It was the same as a chine slap familiar to the in-V powerboat owner at anchor. Other designers have made the front foot deeper so that it sinks in water at rest. Owners have found that putting an extra load on the bow and lowering the centreboard when anchored at night reduces the noise emphasized by the thinner and lighter construction as a whole.
