Solander 38Solander 38

Solander 38 is a self-sufficient, solar-electric, coastal cruising power catamaran.

This website is an effort to document and share designs, processes, and research from Solander 38, the first vessel reference design by Rising Tide Research Foundation. We’ve made this site to celebrate the work of those involved and to openly share the ongoing successes, failures, and lessons learned from the first build of the designs, Catalyst, and its real-world use over time.
