Maritime Journal news bulletin on the three new SAR classes for SSRS by Birger Kullmann Design Naval Architects (copy below): Just a quick note from the Naval Architect: The K9, K12 and K15 are very deep-v designs and you do not use "a conventional propeller shaft" on such hull designs! Furthermore the very reason for using waterjet is not that a "propeller shaft would be vulnerable", - it is simply that the people you aim to rescue are vulnerable! Anything other than waterjet propulsion on a true SAR vessel is a "No-No". See www.kullmann-design.eu and www.kullmann.no for more info.
The Swedish Sea Rescue Society (SSRS) is introducing three new classes of purpose-built rescue vessels designed by Birger Kullmann Design, strengthening its operations along Sweden's coastline and archipelagos with entirely new technical solutions.
