Revision as of 16:46, 11 April 2010
Information about "sustainability ships" -- sailing vessels that push the envelope of green technology, inspire innovation, and could become or inform the next Beam Reach research vessel. The focus here is on organization of practical engineering data, cost-benefit analyses, and equipment sources.
Case studies
Gato Verde, 1995 Fountaine Pajot Venezia 42' Catamaran (LOA 42’, LWL 40’+, beam 23’, dry weight 19000lbs, full capacity weight 23500lbs) Orignially powered by dual 27hp Yanmar inboard diesels, this 12.75m Fontaine-Pajot catamaran's saildrives are now connected to larger 3 blade 17”X15” props and dual 48V Lynch motors assisted by a 14kW biodiesel genset and custom "Enermatic" controller by Ample Power.
- Vessel system description (by Captain Todd Shuster)
- 2006 blog article with info on in-air noise reduction (old diesel vs new electric)
- 6/2009 note: The motors are Lynch LEM200 series rated at 9000 watts. When pushing the boat at cruising speed (6 knots) in calm conditions the motors draw approximately 10800 watts (2x5400 watts). The Lynch motors are coupled to Yanmar SD20 sail-drives which have an internal 2.64:1 gear reduction turning three blade 17”X15” props. I don't know the RPM of the props or the motors at cruising speed.
Largyalo Wharram Pahi 63, LOA 20m, beam 10m; Fischer Panda propulsion system; solar cells, SVO generator; wind generators?
- home page
- the ark of ideas (motivation for the ship and voyages)
- blog (mostly in German)
Derek M. Baylis 65' monohull with attention to energy efficiency; unstayed masts;
Sanderling ~10m Al Wharram-inspired catamaran (Reid Harbor, San Juan Islands, WA, USA) No bottom paint, wooden masts (from Stuart Island trees) stepped in gravel, and blue tarp sails ($60 each).
Aguita 50' Al catamaran Proven in Pacific, some solar
Oceana Ranger 23.5m Al catamaran Multiple transpacific voyages as hospital ship, sleeps 10-14, built 1986 in Oregon; rain catchment, redundant systems, 4-stoke outboards on inflatables, solar panels, wind generator.
