Abstract: A swimming ladder system can include a ladder configured to be mounted to a support surface, and a pivot connected to the ladder for anchoring the ladder to the support surface. The pivot can include at least one detent for arresting movement of the ladder at a lowered or operative orientation, a raised or stowed orientation, an intermediate orientation between the lowered or operative orientation and the raised or stowed orientation, and so forth. In some embodiments, the swimming ladder system includes a ratchet lock with a latch, where the latch can be moved between a first orientation for arresting movement of the ladder in a first direction and a second orientation for arresting movement of the ladder in a second direction.

Abstract: The cover delivery device (e.g., for use in selectably covering a watercraft) can include a first mobile support assembly, a second mobile support assembly, a drive shaft, and a cover carrier mechanism. The first mobile support assembly is mounted to and configured for movement along a first rail. The second mobile support assembly is mounted to and configured for movement along a second rail, which is generally parallel to the first rail. The drive shaft extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism is configured for selectably deploying a cover carried thereby, with the cover carrier mechanism being configured to respectively roll and unroll the cover relative thereto.
