Home Page Leadership In Yacht Stabilization  The Theory Behind Sea Legs T-Foil Yacht Stabilizers. As experienced boaters know, the motion generated by rolling seas will ruin an otherwise perfect day. Sea Legs transom-mounted yacht stabilizers, are designed to create a lifting force within the outboard section of the transom. Each of the two hydrofoils produces a rolling motion opposite that created by the sea, thereby counteracting the rolling sea. The key to this design is based on modern aircraft technology combined with marine hydrofoil technology. Sea Legs control the motion of your boat through the water the same way an airplane tail section controls aircraft pitch and yaw, using the two T-foils mounted on the transom. Roll is controlled like ailerons on an aircraft, except Sea Legs controls roll from the yacht's transom. Complete Yacht Motion Control Conventional Roll-Fin stabilizers only control roll. With Sea Legs yacht stabilizers, -all motion- is controlled. Each of the two T-foils induce a lever action at the transom by utilizing lift forces generated by their own aerodynamic shape. Sea Legs stop uncomfortable yacht movement around the pitch, roll and yaw axes. This provides total motion dampening | The Difference is in The Design  Conventional Yacht Roll-Fin Stabilizers only control boat roll. Sea Legs Yacht Stabilizers control all yacht motion underway and .....roll at anchor!
The vertical surfaces of Sea Legs T-foils generate lift, which dampens boat roll and ...improves steerage in following seas. The horizontal surface produces lift which dampens boat roll and ...pitch buffeting.
With this design, the entire T-foil works to reduce uncomfortable boat motion, with or without hydraulic control. In active mode, the amount of yacht roll generated by sea conditions is measured by a solid-state roll-motion sensor. This sensor sends a signal to the Sea Legs digital hydraulic control system. The system directs hydraulic foil-actuators to move in opposing directions, like aircraft ailerons, at just the right angle and velocity to counteract yacht roll. Simultaneously, the engineered shape of the T-foils passively controls your boat's pitch buffering, and yaw in following seas. This continuous process produces the smooth comfortable ride you experience on a Sea Legs-equipped yacht. Competitive Roll fin stabilization, -by design- only controls boat roll .
Roll Control at ...Anchor?  Today's yacht owners are commanding the ultimate in comfort. From interior accomodations, to comfort at anchor. The market demands it! We supply it. In addition to Sea Legs roll control at anchor, and ... total motion control underway; CME offers optional computerized thruster control, to automatically maintain vessel direction into the swell at anchor or at low speeds. Used in conjuction with the Sea Legs T-foils, yacht comfort is increased to a level never experianced before...at Anchor! |
