Patent number: 11945557Abstract: A suspension system for supporting a body relative to at least four points, including: a respective front left, front right, back left and back right support arrangement between the respective point and the body, each respective support arrangement including a respective resilience arrangement and a respective control ram, each respective control ram including a respective compression chamber forming at least part of a respective compression control volume; a control arrangement including a first and a second diagonal reversible pump for displacing fluid between diagonally opposite compression control volumes. Each respective resilience arrangement can include a respective damping arrangement to restrict and/or selectively prevent compression and/or expansion of at least a portion of the respective resilience arrangement. Each respective control ram can further include a respective rebound chamber, the front control rams being cross connected and the back control rams being cross connected.Type: GrantFiled: December 6, 2019Date of Patent: April 2, 2024Assignee: Nauti-Craft Pty LtdInventors: Laurence John Walker, Michael James Longman, Richard Monk, Ross McNab

Patent number: 11345442Abstract: A hull locating arrangement for a vessel is disclosed that has a body at least partially suspended above at least a first hull by at least one support. The hull locating arrangement includes for the first hull a forward locating linkage and a rearward locating linkage, each of the forward locating linkage and the rearward locating linkage being connected between the first hull and the body to together constrain said hull in the lateral, longitudinal, roll and yaw directions relative to the body. The forward locating linkage includes a forward radius arm and a drop link, the drop link being pivotally connected to the radius arm. The rearward locating linkage includes a rearward radius arm connected between the body and the first hull.Type: GrantFiled: December 7, 2018Date of Patent: May 31, 2022Assignee: Nanti-Craft Pty LtdInventors: Michael James Longman, Richard Monk

Patent number: 10556650Abstract: A suspension system for a water craft, the water craft including a chassis which is at least partially suspended above or relative to at least a first hull and a second hull. The suspension system includes a first hull locating arrangement for at least partially constraining the first hull in a lateral, a yaw, a roll and a longitudinal direction relative to the chassis, the first hull locating arrangement comprising a first, a second, a third and a fourth link arranged to directly or indirectly connect between the hull and the chassis. The first, second and third links each extend in at least a lateral direction relative to the chassis and contribute to a lateral constraint on the first hull relative to the chassis. The second link is longitudinally spaced from the first link relative to the chassis to contribute to a hull yaw constraint on the first hull relative to the chassis.Type: GrantFiled: March 3, 2017Date of Patent: February 11, 2020Assignee: Nauti-Craft Pty LtdInventors: Michael James Longman, Richard Monk

Patent number: 9849947Abstract: A control system for a suspension system of a multi-hulled vessel, the vessel including a chassis portion, at least two hulls moveable relative to the chassis portion. The suspension system of the vessel provides support of at least a portion of the chassis above the at least two hulls, and includes adjustable supports and at least one motor to enable adjustment of a support force and/or displacement of the adjustable supports. The control system includes a fender friction force input for receiving at least one signal indicative of a friction force on a fender portion between a fixed or floating object and the vessel chassis portion, and in response to the fender friction force input, the control system is to adjust the support force and/or displacement between the chassis portion and the at least two hulls to reduce or minimize the friction force on the fender portion.Type: GrantFiled: December 11, 2014Date of Patent: December 26, 2017Assignee: Nauti-Craft Pty LtdInventor: Michael James Longman
