The present disclosure includes recreational watercraft including a drop down boarding point. One example includes a hull, an open platform passenger deck, and a plurality of sides, continuous from the hull. The watercraft includes a panel drop down boarding point, hingedly attached horizontally to the hull, for ingress and egress of persons to the watercraft. The panel drop down boarding point includes a first surface interior to the watercraft when the panel drop down boarding point is closed, a second surface, opposite to the first surface and exterior to the watercraft when the panel drop down boarding point is closed, and an aperture formed between the first surface and the second surface and having an opening in an end surface of the panel drop down boarding point. The aperture is sized and shaped to house a retractable ladder and for the ladder to extend out through the opening.

The present invention relates to a hybrid dynamically installed anchor with a folding shank and a control method to keep the verticality of the hybrid anchor during free fall in the seawater, which can be applied to the field of offshore engineering. The hybrid anchor comprises a folding-shank plate anchor, a ballast shaft, an extension rod, a plurality of rear fins, and a recovery hole from the front to the tail. The folding shank is not only useful in reducing the water and soil resistance during installation, but also beneficial in improving the directional stability of the hybrid anchor during free fall in the seawater. The re-used shaft can significantly increase the penetration depth of the folding-shank plate anchor and reduce the installation cost at the same time. The control method keeping the verticality of the hybrid anchor can improve the success rate during anchor installation.

Examples of systems and methods for matching a base mesh to a target mesh for a virtual avatar or object are disclosed. The systems and methods may be configured to automatically match a base mesh of an animation rig to a target mesh, which may represent a particular pose of the virtual avatar or object. Base meshes may be obtained by manipulating an avatar or object into a particular pose, while target meshes may be obtain by scanning, photographing, or otherwise obtaining information about a person or object in the particular pose. The systems and methods may automatically match a base mesh to a target mesh using rigid transformations in regions of higher error and non-rigid deformations in regions of lower error.

A portable marine anchoring device maximizes holding capacity while anchored into the ground. The device is fabricated from lightweight aluminum.

The present invention provides for a method of marine construction. Said marine construction is based on an external perimeter and inner area and comprises seabed lying elements and floating elements. The marine construction of the present invention comprising fixed elements that are placed on the defined perimeter of said marine construction. Said fixed elements are lying on the seabed. And further comprising floating elements that are placed in the inner area the marine construction, defined by said external perimeter. The marine construction is capable of being deployed at a variety of distances from shore, at a differential nature of sea bed, and to be able to carry out different tasks and destinations, such as but not limited to airport, residency, army base, power station, port, marina, other infrastructures, etc. and any combination thereof.

An anchor system including an anchor having a body member and a first arm pivotally coupled to the body member. The first arm is movable between a closed position wherein the first arm is positioned adjacent to the body member and an open position wherein at least part of the first arm is spaced away from the body member. The system further includes a second arm pivotally coupled to the body member and movable between a closed position wherein the second arm is positioned adjacent to the body member and an open position wherein at least part of the second arm is spaced away from the body member. At least one of the first or second arms has a cavity that is exposed when the at least one of the first or second arms is in the open position. The at least one of the first or second arms includes a protrusion extending therefrom.
