I really can't understand how this could happen. Obviously the so-called helmsman didin't have a clue about the RIB and hadn't the slightest clue about passenger safety. Please do name and shame, if only to ensure it doesn't happen to anybody else on here.

Something similar happened last yr at RIBEX with a RIB not flying level and being poorly driven: RIB-X/Falcon 700

Agree there - he should have checked but I know for a fact if I was suffering that much I would have spoken up - or just pulled the kill cord out!!!!

I agree too many people don't have a clue about balancing a boat - they just don't seem to understand c of g or lateral balance - God help them if they were ever involved in light aviation!!!

All the more reason for the policy of all PAX vls plus others where possible should have the helm aft and all pax in front. Thus anyone with discomfort or concern simply has to raise their arms in the air. Our policy is always to fit out aft consol.

For some vls this can cause a problem as the tanks are also fitted aft and with an aft consol etc this affects balance in the longitunal. Cod Prawn ... sorry to but in but this is balance ie. during construction, whilst trim ( not to be confused with outboard trim) is transverse and longit. trim using cargo (pax).

A shame about the incident but unforunately they do occur in all environs. If at sea then such needs to be reported to MAIB.

Cheers

Couldn't agree more John - obviously a true commercial RIB is going to be very stern heavy until carrying it's full pax load which is the way it should be. Conversely most leisure RIBS have their consoles too far aft which combined with the engines and passengers also at the back make them very stern heavy ALL the time!!!

Oh dear Codders, you're talking bollox again. You really should try and think before putting finger to keyboard. most leisure ribs, come off it. some leisure ribs sure but most no i dont think so. In fact I cant recall personally being on a leisure rib where I would say the console is too far aft. And I've been on a few ribs. Mebbe we're talking about your virtual ribbing world again eh?

Am I really??? Apart from Humber just LOOK at most leisure RIBS!!! Console amidships - engine at the back - passengers at the back - why not move the console further forward???

Notice I said MOST - not ALL!!!!

Depends on a lot more factors - where is the fuel tank? Where is the hull's C of G? How is the RIB loaded?

Many small RIBs need weight up front for pitch stability, hence the console further forwards, but the further back you sit, the less you move, so it's desirable from a comfort point if view to sit as far back as possible, and put the fuel and luggage up front. Bigger (ie longer) RIBs are easier to balance, and I've found that as I get to know the handling of our RIB better I have been able to lighten the bow and gain the advantage of running the boat lighter, hence faster, and benefit from better engine trim control.

Very true Rich BUT if you start to take off from big waves you will find that the bow tends to flip up and the stern crashes down - a classic example of why bow ballast tanks were invented I suppose!!!
