Dotan Maritime Enterprise (DME) is a Latvian sailing-tech company founded in 1992 by Dr Leonid Chernin, maritime engineer (PhD) and active sailor. Since day one, we’ve been dedicated to developing and producing innovative kick-up rudder systems for dinghies and catamarans — improving performance, safety, and ease of handling.
Our rudders are known for their patented kick-up mechanism — no ropes, no springs, no rubber bands — and have earned a reputation for durability and simplicity across generations of sailors.
Over the past 30+ years, we’ve delivered to more than 50 countries — from New Zealand to Norway. Many customers return to us after 15–20 years for spare parts or replacements — a clear sign of long-term trust and product longevity.
Launched new catamaran rudder set with eco‑friendly packaging and compact shipping design.
Introduced budget plywood rudder blades for Optimist — ideal for sailing schools and training centers.
