New Rib

Adam Younger · 26 July 2004, 18:06

After much rough / choppy weather boating with our new demo RIB we have at last had a chance to play in some better weather and get some photo's. Taken off of Yarmouth last week.

The boat is a 6.5M K4+ RIB with a 140 Hp Suzuki. It is an all new stepped hull design - but purpose designed as a RIB and also to perform and handle throughout the speed range. This is the first boat but we are now building boat number 4.

good pics..... and Fantastic rib,

well happy with the demo the other week, I was really impressed with the handling and performance of the hull. Excellent design and good work.....

Just curious.. just by looking at the pictures I have one question.. Do the tubes form any practical purpose on this boat, other than fendering?..

Just look at the picture on this thread

Surprising as it seems from these pictures, it looks like the tubes do touch the water at rest!

Hi Jono

'Do the tubes form any practical purpose on this boat'

If you count buoyancy, stability and handling - then the answer is yes!

Hi Tim
Will definately arrange something soon - just about to go to Sweden for a week - will be in touch when I get back

Cheers

Good pics, look forward to have a go on her one day.

All the best and good luck

Adam, it gets up high, is it particularly light?

Jono · 27 July 2004, 08:19

I knew that

..but seriously? From the latest picture I can now see that at displacement speeds the tubes touch the water so can understand the tubes providing stability at those speeds/rest, but how do they affect the handling at speed? I know my tubes do, 'cause they're great big heavy things on a big heavy hull and so "dig in" during turning at speed. Do the tubes on this boat "work" the same way? Am I digging a hole here? Shall I shut up before everyone else realises how ignorant I am?........I'll get me coat!.. TAXI!

Jono come back from the photo I would have thought the same thing especially in photo 1!
But then we have photo 4 to make things clear.

..........TAXI for Jono

p.s I wondered the same thing but decided not to put my head above the parapet.

Great-looking RIB Adam. Another head-turner.

Every good wish.

Do they ever?

Feck off Nobba! You know toobs make a boat faster and the helmsman more virile......

Think we know a certain ex-hardboater who will be daydreamin when he sees this...

Really a 'horses for courses' thing - and what we have created in this version is a sports RIB. The tubes do come into play in terms of handling when pushing hard in turns and of course provide large amounts of buoyancy in rough weather (and we have had plenty of that recently).

The boat is built fairly light - without going to extremes - and as such the performance is very good - which very much goes with the whole lay-out, hull design and tube design.

However we are looking at producing a 'cruising' version from the same hull. This would mean the tube diametre going up by about 50mm and with the tubes mounted slightly further outboard and canted outboard in the main body of the boat. This would also then lead to an increase of approx. 75mm in internal beam and approx. 45mm of internal freeboard. Again back to 'horses for courses'. Performance would drop of a bit but the hull we have created is efficient and the idea is that it does not need massive horsepower to obtain good speeds.

Hi Adam,

That is a great looking sports rib you have produced.

Apologies if I am reopening an old can of worms here, but can you please explain the advantages of the stepped hull? As I understand the principle, the craft will be more efficient when on the plane, but what effect does this design have during high speed cornering?

Cheers.
