Tornado rib seems a good only 9 years old 5.8 with good engine
but have been told tornado ribs are PVC tubes and not Hyperion does this decreases there value

yes if all else is the same. hypalon is heavier and harder wearing but also more expensive and having used both it would depend on what i am using the boat for and how often. there is a lot of negative a pvc but wear patches for key places and they are more than fine. as pvc is lighter it means less hp required and in some cases can mean unbraked and not a braked trailer. Condition of both though is the key as both cost a lot to replace!!!

That's something I'd not considered previously! In your experience, what would the typical weight savings be on a 6m RIB?

Thought tornado were PU not PVC

Hi

sorry others will know on here but the 5.8 with a 100 suzki (new engine) came in with no fuel a some basic electrics and bits at 520kg so depending on your engine the tornado 6m it says is the same weight see https://tornado-boats.com/ribs/ so when we sold a trailer he was ok to be unbraked ie we can go to 590kg unbraked so he just loaded his boot with extra fuel and the anchor. unbraked = a lot cheaper and easier to look after so it can make a difference.

Er thanks. Reading between the many lines, could I be forgiven for assuming that you have no idea? It's just that you seemed very sure when you were advising the OP of your professional opinion...

That sounds like a job involving pi so I am duly summonsed!

As far as I can see Hypalon comes in quite a wide range of densities, from as low as 880g/m2 to 2210g/m2 whilst PVC seems to be typically 980g/m2 (other ranges may be possible). So theoretically some Hypalon boats could lighter! But I believe 1500g/m2 is the most you would find on “normal” boats.

Assuming the tubes are a total of 12m long (total), and 0.5m diam you are looking at less than 10kg difference between 1500g/m2 and 980g/m2 ...

(The only data I could find for PU was the same density as Hypalon and more puncture and abrasion resistant).

Ribcraft standard commercial spec Hypalon is 1300 gsm. The heavy duty is 1500gsm.

You'd save nearly 3kg by leaving them deflated.

The thought of pie sparked my interest.

I am 100 pecent sure it lighter. my job is to get trailers for my clients for the least amount of money and there is often just a few kg between braked and unbraked, single and twin axle. Do I need to know the spec differnece lol .... no. I just need to make sure its legal and safe.

KG's on trailers count. we often get cases where losing 10Kg or so can mean the difference between unbraked or braked or single to to twin axle.

so if your working to a 10 kg tolerance on braked and unbraked just a couple of gallon of petrol extra for instance will push an unbraked trailer over the limit bit fine that for me IMO

ashtonmarine · 26 February 2019, 10:04

Clients often would prefer to take things out of the boat to save a lot of money and nothave brakes or twin axle. its not our money and as long as its legal and they know the limits then that is a choice they need to make not us. this happens even more on big boats as they are often just over the boat capacity of the trailer so the only way they can do it is go go and check the weight and see what can be taken out to make it legal. we have this with a cheetah at the moment boat is 2900kg and we can go to 2850kg and it needs to be on a road legal trailer. the client is working out how do to this as we speak!!

if you get in touch with KRAKEN RIBS on here they will tell you all you need to know about tornado one of the lads dad was the owner of tornado and as far back as i can remember they were PU fabric and stand up well to use.

cheers

Tornado certainly used to be PU tubes. It's a good fabric - very hard wearing, easy to keep clean.

As for working to 10kg tolerances for trailers etc - 10kg on on a 750kg trailer would be too close for my comfort. If it rained and you forgot to pull the bung out/you left some bottles of water in a locker etc etc you could push yourself over into the illegal bracket if you had the very unlikely misfortune to get pulled over right at the wrong moment.

vernon57 · 27 February 2019, 07:54

I actually still have my Tornado 5.8m rib which I bought new in 1994. It originally had PU tubes which I had replaced when it was about 15 years old mainly because I neglected it and left uncovered outdoors for years. The tubes were very hard wearing seeing mine was used for diving all around the uk. It is a great rib and handles beautifully even in rough seas. I haven’t followed the thread in great detail but I tow mine on a 750kg trailer sometimes loaded with diving kit with no problems. It is not a heavy rib in my experience and has travelled all around the coast. Cheers Martin

vernon57 · 27 February 2019, 07:59

I forgot to add that mine is a braked trailer which actually is a pain being constantly immersed in sea water for launching. I normally dismantle and clean twice per year although I have not yet fitted hub wash connections to my drums. Cheers Martin
