New wave piercing RIB

[John Kennett]

How about this for an interesting design! The Very Slender RIB marketed by Venom RIBs -- the first production wave piercing RIB.

Betcha it bow steers when going down hill.

I dont often coment on other designs but this one is maverick.

JW agree with you 100%.

Also may be ok in a short chop but not in a big sea. Would go dam well astern though !!

I have no racing experience whatsoever but I guess it may have an application (ish) there.

I remind that with the case of bigger and bigger RHIBS or ones with fancy designs ..... are we trying to make something better than possible out of a fundamental product.

If you want a 20m boat sitting proud of the water then what is the use of tubes... if it is stability then look at the hull design rather than the tubes. Same applies to fancy racing hulls.

Suggestion is go back , define what a RHIB is along with its intended use. OK make it pretty or useful but do not try and make it something that the ethos of a RHIB is not.

I guess the point is that novelty and inovation are a mile apart. The RHIB 40 years ago was the inovation.....................

Hear hear Quinquamarine,

What is the point of tubes on a big boat.

I think some of these company's lose sight of what they are building. Or add tubes because it is the in thing, and means they can charge over the odds for their boat.

The basic RIB design is the saviour of small boats. Make the boat large and most of the time it can handle anything thrown at it. It doesn't need tubes to lift it out of the waves its already above them.

Nothing compared to the one I saw at Ribex - the long black thing!!!

Having said that this wave piercing concept is not exactly new!!!

With regards the Turbinia,

The Navy have two boats similar in looks and design under development/testing at the moment.

However they ain't RIBS and they have an open back. So if they are too efficient and cut through a large wave then they will take on rather a lot of water.

Even if they have a means of clearing the water it will still slow the boat down for a while whilst its clearing.

That was the first thing that I thought too!

Given their background as coaching boats for dinghy sailors, they may well be brilliant at relatively low speeds in a short chop. I'm not sure I'd be too keen on going very fast in one though, or any speed at all in a big sea.

Has anyone seen one in the UK?

and what would you have said 40 years ago john?? probably novelty and innovation are a mile apart. A sports boat does not need tubes, a sports boat nth years ago was the innovation......


good on em for trying, i personally dont think its innovative enough, the black one at ribex (where is that now??) was more innovative and inventive.

Without new ideas and designs where would our world be now?? let alone our boats!!!

Now pass the matches as edison hasnt invented the light bulb yet as we are to scared of change. what you mean we dont have matches neither!!!!

Actually Edison did NOT invent the light bulb - if was a British bloke called Joseph Swan - that one ALWAYS annoys me!!!!

Turbinia was just ONE example - what I was trying to show was that back in those days there were many boats shaped like that - long and thin meant higher speeds and better fuel economey.
