Embodiments of the disclosure are drawn to apparatuses and methods for packaging and distributing a marine energy storage system. Battery packs including one or more battery cells and a compliant layer enclosed in a sealed housing are disclosed. Vessel hulls with battery packs structurally integrated are disclosed. Vessel hulls with battery packs mounted to an inner surface of an outer hull are disclosed. Vessel hulls including compartments for inserting battery packs are disclosed. Vessel hulls including battery packs mounted in a ballast of the hull are disclosed.

A method of assembling a watercraft of a family of watercraft includes, when assembling a first watercraft, attaching a front hull panel to a rear hull panel such that the front hull panel extends forwardly of the rear hull panel. The front hull panel and the rear hull panel form a hull of the first watercraft. The method also includes, when assembling the second watercraft: attaching a hull extension panel to the rear hull panel such that the hull extension panel extends forwardly of the rear hull panel; and attaching the front hull panel to the hull extension panel such that the front hull panel extends forwardly of the hull extension panel. The front hull panel, the hull extension panel and the rear hull panel form a hull of the second watercraft. The second watercraft has a second hull length greater than a first hull length of the first watercraft.

A hybrid personal watercraft combines features of pontoon boats and deck boats, in a cost-effective and versatile package. The watercraft includes port and starboard sponsons which combine a pair of outboard flotation cavities. A space below the deck and above the hull bottom creates at least one, and potentially up to three additional flotation cavities, which may also be used as storage areas accessible by an access door in the bow of the watercraft and/or a set of hatches in the deck. The watercraft may be efficiently produced assembled from polymer materials, such as thermoplastic polyolefin (TPO).

A method of monitoring wave slam on a vessel includes measuring acceleration forces from mechanical shocks on the vessel using one or more sensors communicatively coupled to a computing unit. Generating real-time acceleration information representative of the wave slam based at least in part on the data obtained from the sensors. Generating acceleration prediction information representative of a predicted wave slam based at least in part on the generated real-time acceleration information. Presenting at least one of the generated real-time acceleration information or acceleration prediction information to an intended recipient.

This disclosure describes hybrid chine hulls, marine vessels including hybrid chine hulls and methods of manufacturing and using hybrid chine hulls. An exemplary hybrid chine hull includes a keel, a single chine section, and a double chine section distinct from the single chine section with respect to a longitudinal direction of the keel and positioned aft of the single chine section.

A hull for low drag boats has, from bow to stern, a deep V-shaped keel (10) whose dead-rise angle decreases up to a flattened bottom (30) in the stern, and sides (20) comprising side chines (200) protruding downward from the flattened bottom that is not inclined upwards.

A pontoon boat includes port and starboard pontoons and cross members connecting the pontoons. A shock absorber may be installed at each point of connection of the pontoons to the cross members. A cross member may be embodied as a double-webbed beam having first and second parallel flanges and first and second webs disposed between and connected to the flanges. Each pontoon may include a two-stage lifting strake having a first surface and a second surface inclined from the first surface.
