About SR-Endurance 8.0
SR-Endurance 8.0 is a self-righting aluminum monohull designed for extended uncrewed work beyond sheltered survey sites. Direct-drive electric propulsion provides a 5-knot survey cruise and speeds above 9 knots, while the vessel is described as operational in Beaufort 7 conditions and survivable in Beaufort 9.
A one-metre moon pool, hydrographic winch and A-frame support multibeam sonar, DVL, ADCP, USBL, acoustic modem and towed-instrument deployments. Published endurance figures vary with operating profile: the dedicated specification states up to nine days at survey speed, while the current class page advertises missions up to fourteen days. Payload capacity is listed at 300 lb.
