Hull type: Custom designed "boxy" hull made from 1/4" ply, sealed with epoxy resin and fibreglass taping on the seams.
Rig Design: Dacron sails and aluminium tubing for the mast.
Power source: 6V 4.5W solar panel and 4400mAh 3.7V lithium batteries.
Actuators: 0.5 RPM, 12 VDC motor from servocity controlling the sail. No rudder.
Sensors: Ublox GPS
Communications: Iridium Rockblock modem
Computers: Arduino Mini Pro
Other Interesting Things: The boat design is very simple, plywood with epoxy and some fiberglass taping. The key element is that the boat has no rudder. She will sail across the wind when there's enough to heel her, and gybe downwind to go directly downwind. This allows for very low power consumption.
