Abstract: A hull (1) for sailing craft enables water gliding performances to be enhanced. The hull (1) for a sailing craft includes a bottom (2) which has a particular profile. The bottom (2) includes a rail (3) shaped from the stem up to the transom, the rail (3) being formed by a flat axial sole (6) linking two parallel passageways of the stem to the transom, of similar width, of similar depth of the water inlet at the transom exit, the passageways derived from the sole (6) have a cross-sectional profile on either side of the sole (6) to form two V-shaped inclined planes (9, 10) and are terminated by two arcs of a quarter circle which are further extended by two other inclined parts (13, 14) forming another V-shape less inclined than the first and leading to the upper works (15, 16). The invention is applicable to boats.

Abstract: Abstract of the Disclosure A method and system for time stamping and authenticating packets of financial data, like orders to buy or sell and confirmations of such orders and resulting trades. The packets are stamped and encrypted multiple times as they enter and leave communications networks and during market processing. Market data, including information about all of the orders and trades generated at the market, is likewise time stamped and distributed to subscribers. This resulting timing data can be used in an algorithmic trading application to make trading decisions. When multiple markets are so equipped, an accurate time-aligned database of market activity may be utilized to develop algorithmic trading applications or for forensic purposes. Packets can also be rerouted or switched to a private network for multicasting to subscribers. The packets are processed to preserve proper handling by downstream routers and switches even though timing data is added to the application layer.
