A number of offshore records don’t allow the use of stored power not generated by a human. It’s common to see electric winches and hydraulic controls on 100 footers, with the diesel running the whole race to power the winches and hydraulics, saves on bodies. However the 100 footers designed to beat ocean records have more people and more winches as they must be entirely human powered. See Comanche. After she broke a bunch of records her winches and grinding pedestals got pulled and hydraulics installed.
