Sunwater Marine Demonstrates Clean Energy Technology With Solar-Electric Catamaran Featuring Live Music On Board From Edge Of The West

The catamaran, Ramblin’ Rose, will demonstrate electric propulsion while powering a live band with solar energy at the Coronado Ferry Landing

San Diego, CA - April 13, 2021 -- Coronado-based Sunwater Marine, which designs and installs renewable energy systems for boats, will showcase the latest clean energy technologies they are offering with live music onboard their solar electric catamaran, Ramblin’ Rose. The performance by Edge Of The West, a 4 piece “Cosmic Honky Tonk” band from Santa Cruz, will be 100% powered by the sun using Sunflare solar panels. The boat will also be propelled by a silent, emissions-free electric system from Oceanvolt. This concert and demonstration will take place at the Ferry Landing in Coronado from 3:30 to 5:30, Friday, April 16.

“We thought this would be a great way to highlight what is possible in renewable energy systems for boats - using Sunflare solar panels, and Oceanvolt electric propulsion - and have some fun in the process! The great thing about this propulsion system is that it is clean and quiet, and will not interfere with the music. No noise, no diesel fumes, only music powered by the sun.” says James Richmond, President and Founder of Sunwater Marine.

Ramblin’ Rose, a 2015 Leopard 40 catamaran that is a full-time charter docked in Coronado, CA, has been re-fitted with the Oceanvolt ServoProp propulsion system, 1.8 kW of Sunflare solar PV cells, and 42 kWh of Lithium Iron Phosphate battery storage in two 48 V battery banks. It is available through Seaforth Boat Rental in Coronado.
