Offshore
Maybe it would be useful to define "Offshore" before we all roll out of the pram?
I can't - but clearly miles offshore isn't the defining quality - I've accompanied an SR4 from Donegal to Islay (return trip in a day) but I wouldn't call it an offshore RIB. I was in a 6.5m Redbay and I'd say the same about it!
Range, seakeeping, reliability, nav & comms, safety gear, crew seating all have to contribute something.
I'd lean towards "A RIB capable of making a long passage in worse than expected conditions while keeping crew safe and (reasonably) comfortable, yet making useful progress"
