The present invention affords a regenerative electric drive refrigerated unit for a conveyance vessel, thereby providing temperature cooling in a compartment of the conveyance vessel. The ramp assembly includes a counterbalance comprising a lug associated with the ramp portion so that movement of the ramp portion toward the deployed position moves the lug along an arcuate path in a first direction, and movement of the ramp portion toward the stowed position moves the lug along the arcuate path in a second direction. The image file is transmitted, together with at least one of the sender identifier, the subject identifier and the scan condition, through the network to one of the external stations indicated by the stored destination identifier. The ventilating fan box may be located within the hull or the cowling of the outboard motor. The middle wall has two middle bars and a middle board connecting the middle bars. A determination is made, in response to the processing, that the second data associated with particular first entity is not stored in the local cache.
