RIB or not?

SDGANDER · 24 August 2005, 18:09

Not sure if this has been done before but...

When is a RIB not a RIB... when does it simply become a speedboat with tubes stuck on?

DGR · 24 August 2005, 19:35

I dunno, but maybe when the tubes aren't in the water when it is at rest? Then (I would have thought), it's a speedboat with an air bag......

...I stand to be corrected......

Does it matter as long as it gets your Juices flowing then it has gota be cool!

Surly by definition a RIB is simply a boat with a rigid inflatable part on it (normally a tube). Does it matter if the tubes arn't in the water.

Jizm · 24 August 2005, 19:53

Don't really think it affects the name if the tubes aren't in the water mere the satbility. Some say it's bad design.

RIGID - the hull / deck
INFLATABLE - the tubes / sponsons
BOAT - what it is.....

surely?

didn't this convosation come up before , - if a rib with tubes out of the water is a GOOD rib ?

My view is , most bigger ribs i've seen has its tubes out of the water , it's only smaller ribs that have it's tubes half in the water ,so my question is- wouldn't tubes hangin the water slow the rib down a bit

SDGANDER · 24 August 2005, 19:59

DGR - yep that was my feeling too.

Rogue Wave - the missus does that but not sure she is a RIB!

Tim M/Jizm - so if I put tubes around the Wightlink Ferries does that make them a RIB?

My definition is that if you rely on the tubes to stop your boat from sinking whilst going about your boating....It's a RIB!! Simple as that.

I asked the RIBCRAFT guy and the boat can float and run just fine without relying on the tubes

do to the fact that they're called RIBcraft i am assuming that the tubes dont need to be in the water they just need to have a general purpose....or maybe i should og back and tell the guy to change his companies name.

So if you stuff a wave it won't capsize and sink then?

Hannah, I consider my RIB to be reasonably large and at rest it sits with a goodly proportion of its tubes in the water. Under power its just the rear end that kisses the water... it's not the fastest RIB in the world, so your assumption that the drag of tubes will create an issue at speed would appear correct. On the flip side, it's pretty damned stable and can be thrown about with gay abandon... and yes, as Rogue points out.. it's gotta look cool..

If you are somehow able to burst all 5 tubes and then try to get back to the dock you deserve to have your boat stuffed and capsized for being such an idiot. ive never heard of an instance where all the tubes on a RIB have popped...

Yeh but read your your post again!

The RIBCRAFT guy has told you that his RIB's can float and operate without the need for tubes......So if you belive him ask him to demonstrate this fact in normal Sea conditions by deflating the tubes 3 miles offshore. If it's a true RIB it won't get far, but if its a hard boat with "GENERAL PURPOSE" tubes like you seem to belive, you'll get home.

Eh? I don't think anyone would say that tubes are unnnecessary on a RIB for them to operate effectively!! All Ribcraft are saying is that there is sufficient built in bouyancy in the hull for it to float if the tubes all deflate - which is very unlikley!!

I've also been told that my RIBcraft will still float with all the tubes deflated, but that doesn't mean I'm going to try it. The guys who coded my RIB have tried it (not on mine, but as part of the type approval) - and apparently it still floated.

And it's still a RIB...

The tubes on mine are pretty much always in the water - see attached pictures......we were doing 25-30 kts in most of the pictures, in some reasonable swell - although it doesn't look like it......

Chopppywaters · 26 August 2005, 13:34

wasnt an arguement of wheter the boat will sink or not it was whether its a RIB depending on the Tube Characteristics.....so i think you should read the post again

OK, I'll agree that bouyancy in Hulls will stop the main boat from sinking and is a safety measure, but we're not talking about that....Are we?

But what I said is that my definition of a RIB is a Boat that relys on the tubes to operate normaly. In your statement above, Mr Choppywaters. Was to suggest that a Ribcraft can RUN ie: operate normaly with tubes deflated.

Where in the States do you live, I'm going over there next weekend and you can buy me a pint and we can continue our conversation.
