The winch system (10) includes a winch (14) and a first arrangement (12) supporting the winch (14). A second arrangement (18) is provided for being mounted to a foundation structure in the form of a deck (20). The first arrangement (12) advantageously comprises a first low profile arrangement (16). The second arrangement (18) advantageously comprises a second low profile arrangement (24). The winch system (10) advantageously includes a low profile roller element bearing (26) connecting the first and second arrangements (12), (18) and allowing rotation of the winch (14) about the second arrangement (12), when the winch (14) is connected to the first arrangement (12) and the second arrangement (18) is mounted to the deck (20).
