Rainbow Warrior 3 sets sail

[Deleted member 36384]

Its a strange design indeed. The hull is reminiscent of American style GOM / Mississippi Delta oil rig supply ships; stretched tugs where the back deck was lengthened for cargo handling. It also looks like a Great Lakes ship from the bow at least. It doesnt look like a very hydrodynamic shape for bashing to windward but apparently it is a very energy efficient hull. However, the latest seismic ships, designed to minimise noise (wasted energy) have bows that are very similar.

Anyway, good luck to them. From their web site: -

The new Rainbow Warrior’s eco-credentials include:

A hull shape designed specifically for superior energy efficiency
A-frame mast and sails - optimised for highly effective sailing
Electric drive system (10 knots on only 300kW)
Green ship class notation with Green Passport
Biological treatment of sewage and grey water
Central filling and venting system for fuel and oils to prevent spills
Environmentally friendly paint system
Re-use of engine heat to make hot water
