Desalinator

Properly a reverse osmosis desalinator. This machine takes salt water, forces at extremely high pressure through a special membrane which traps the salt and only allows fresh water through. It tastes horrible, but it is clean water eminently suitable for mixing with power drinks, protein shakes and freeze dried food. By making only just enough water for immediate use, the boats save the deadweight of carrying the tankage that would otherwise be needed.

Doldrums

Downhaul

Any rope or line that pulls something downwards. Often used to hold a spinnaker pole down or to tension the tack of a sail

Drysuit

Clothing made from waterproof often Gore-Tex, breathable - material and using waterproof zips and wrist and neck seals from soft latex rubber; generally with built in boots or latex socks, to prevent the majority of water ingress. Used in severe conditions to enable crew to work in heavy spray or on-deck waves without suffering too severely from cold or hypothermia. Some foredeck crew wear dry-tops which have neck and wrist seals and waist seals of soft neoprene to give greater protection than conventional foul weather gear without the difficulty of getting into a drysuit
