Rainman Watermakers

Portable and modular water production aligned with real cruising routines.

Water production aboard a cruising yacht is less about capacity and more about consistency, simplicity, and how the system fits daily routines. Rainman systems are widely adopted because they allow owners to match water production to real cruising patterns. Portable configurations provide maximum flexibility and minimal installation complexity, while modular installations are typically chosen when continuous availability and operation while underway become priorities. Rainman is also recognised as one of the most cost‑effective commercially available high‑output watermakers on the market, combined with one of the most extensive global dealer and repair networks. Service and support are available throughout major cruising regions, including the Caribbean and Pacific destinations where long‑term reliability and parts access matter most. Bluewater Systems is the official importer and distributor for Denmark, providing local supply, integration support, and technical guidance.
