"THE OLD TRADITIONAL DESIGNS - 'NOT ALWAYS THE BEST WAY! "
Ships and Rough Seas - Power Point
Hours and months are invested by marine architectural designers to stream-line the basic oceangoing mono-hull or multi-hull ship. But regardless of how the design is shaped, or how may luxury suites have an ocean view, a pointed mono-hull vessel continues to follow the ocean contours (waves) up and down, side to side (video link), and a bow wake by any name equals drag and hog & sag. The two photo's below demonstrates the tunnel plugs, ship stresses and bow-plows typical of catamarans, tri-marans, SWATH, SLICE, 'lifting bodies', mono-hull and hydrofoil ships in even mildly elevated sea states. Such vessels all ultimately obey and follow the rise and fall of ocean waves or contours. These vessels all must then slow to speeds of 6-12 Knots in only these modest sea states.

DANGEROUS CATAMARAN BOW-PLOW / TUNNEL SLAM HOG & SAG - Heave, Roll, Pitch, Yaw and Sway
The above photographs shows such real vessels in the real ocean world of the rough seas. These ships remain the "design by default" of modern marine architecture in 2007. Huge investments are made for design of variations of these failing designs, as exampled by the cancellation of the hugely expensive recent Coast Guard Cutter contract cancellation & the decommissioning of the said built vessels - and now the Navy's newer efforts of 'lifting-bodies' ships; seem destined to be effective only in relatively calm waters. The reality is that Trans-ocean transport waters are just not very kind or calm.
Why continue investing more new capital for the replication or modification of slower, safety compromised, ocean slamming ships that predictably, will suffer from pitching, heaving, plowing, rolling, yaw and sway? The known consequences will continue with structural, comfort, safety and sluggish speed challenges. The real world of all trans-ocean surface transport is mostly powered through other than, calm lake-type smooth waters.
Perhaps hesitation is the "sailor's tradition" for the love of pitch, roll, heave, yaw and sway, or perhaps the marine investment and banking communities may be just comfortable with the old concepts that are well understood, or just perhaps any change to the new is difficult. Whatever the reason, the 'new design revolution' is here now, and new ship decisions need to be made. There is now a new and very real choice to be considered; as the H.A.R.T.H. technology is ready now.
New and Better Way ...
Hydro Lance means no roll, no pitch, no heave, no yaw, no sway and no sea sickness with smooth speeds to over 100 Knots in and through calm or though elevated sea states. All other conventional ship speeds are established in calm water only, but Hydro Lance rates it's vessels cruising speeds in and through the elevated sea-state design rating of that vessel design . The reason for more conventional ship's speed-ratings to always be in calm water, is because of wave height, wave frequency and wind forces, associated with elevated sea-states slow all of these vessels to very slow speeds, perhaps of only 6-10 Knots or less. As Sea-states elevate, conventional ships must go up and over waves and swells - and down into the trough.
HYDRO LANCE HARTH 'STATE-OF-THE ART' SHIPS are FAST, Ultra-Stable & SAFER ...
HARTH Heavy-Lift Container Ship HARTH Matched-Speed Aircraft Yacht Carriers HARTH FAST-FERRIES
HARTH TECHNOLOGY Means stability and Speed
NO ROLL, PITCH, HEAVE, YAW or SWAY - within HIGH SPEEDS and with Lower Drag
Up to Seven Times the Fuel Economy Per Ton / Passenger Mile!
Ships built utilizing the Hydro Lance HARTH technology do not follow the ocean waves and contours, but rather averages their forces to an approximate zero force influence, with the vessel remaining level and stable in and through elevated sea states. Bow wake generation is eliminated to negligible levels, obviating a great portion of Froude drag calculations. Other technologies employed are combined to reduce overall drag up to 83% - having up to seven times the fuel economy.
This results in three to six times the cruising speed capabilities vs. the conventional ship. The HARTH built vessel is a very fast, ultra-stable platform in either low or elevated sea-states - at any selected speed. Further, vessel safety is improved having reserve buoyancy throughout the ship and sophisticated electronics. Over a quarter of either or both hulls can be smashed, severed or flooded, while having the vessel still maintaining it's integrity. Safety now has risen to a new standard for the maritime industry consideration.
