Anyone who believes that its ok to travel any significant distance on a RIB sitting on the tubes is either.....
Young fit and stupid
just plain stupid
Crew comfort and reducing fatigue are imperative. The coxn has the best of all worlds, he usually has a nice jockey seat (unless he really wants to shag his back on a bench seat
), he is holding onto the steering wheel & throttle, he can see ahead, is reading the sea and bracing himself accordingly. Front seat passengers (assuming side by side seating) enjoy similar benefits although with a grab rail (if a well set up boat) rather than a wheel/throttle. As you go further back in the boat, passengers have less view of whats going on in front and rely on a good seat/grab rail. The exception to this is if you can stand behind a jockey holding on but even then this can be tiring on a long trip.
It is oh so easy to be enjoying the bangity, crash, whee isnt this fun bit as a driver/coxn and not be sensitive to the cold, tired, please god make it stop, passengers behind you. If those passengers are sitting on the tubes then they are not going to be having fun after the first 30mins.
To compare an Ocean Dynamics trip boat - big & heavy as Richard says, plus used for relatively short distance excursions to a smaller cruising rib merely demonstrates a certain persons lack of knowledge/experience of what it is actually like to go any signficant distance in a RIB.
Mind you with a 9m RIB Codders I am assuming you'll have jockey seats galore?
