A method of operating a watercraft carrier includes activating a handle at an outboard end of a base of the watercraft carrier. The activating the handle releases a locking mechanism of an upright. The locking mechanism is disposed at a distal end of the base. The method further includes rotating the upright from a first position to a second position.

A rooftop mount device for connecting to a roof of a portable gym and for attaching exercise equipment is described. The portable gym is a portable container, such as a shipping container, having a top surface, or roof, to which the rooftop mount is attachable. The rooftop mount device includes connection members. The rooftop mount can also include one or more horizontal stabilization members and equipment attachment elements. The connection members are attached to a roof of the container. Exercise equipment is attached to the parts of the rooftop mount device. The rooftop mount provides proper height and stability for the bars, racks, stands, cages, rigs and riggings, and other exercise equipment that are attached to the container's roof so that the equipment does not move during use by an exerciser. Systems and kits are also described, which include a rooftop mount device, various exercise equipment, and a portable container.

A watercraft carrier includes a base, a hub, an upright, and an actuator. The base includes an outboard end, a distal end, and an upper surface. The hub is disposed at the distal end of the base. The upright is coupled to the hub and configured to rotate with respect to the base. The actuator is configured to release the upright from a locked configuration such that the upright can rotate from a first position to a second position. Displacing the actuator in an outboard direction releases the upright from the locked configuration.

A vehicle assembly includes, among other things, a tie-down bracket including a latch pivotably coupled to a body. A method includes, among other things, securing a tie-down line to a tie-down bracket of a vehicle. The method further includes monitoring a load applied to the tie-down bracket.

A rack for carrying cargo on top of a vehicle is disclosed, comprising a pair of longitudinal support assemblies. Each support assembly is configured for mounting on a crossbar secured across the roof of a vehicle, and includes a stationary base and an extendable rail. Each rail is moveable between a first position in which the rail is substantially coextensive with the base, a second position in which the rail extends significantly beyond the end of the base, and a third position in which the rail pivots downward adjacent a side of the vehicle. Each rail also has a proximal end portion and a distal end portion, with a loading arm pivotably connected to the distal end portion. The loading arm is moveable between a collapsed position parallel the rail and an extended loading position.

A watercraft carrier, for example, for carrying a kayak, includes a base having an outboard end, a distal end, and an upper surface. The watercraft carrier includes a hub disposed at the distal end of the base and an upright coupled to the hub and configured to rotate with respect to the base. The watercraft carrier includes a handle disposed at the outboard end of the base configured to release the upright from a locked configuration such that the upright can rotate from a first position to a second position. Displacing the handle in an outboard direction releases the upright from the locked configuration.
