Material strength 1100 vs 1670 dtx

SixtyNorth · 20 March 2014, 15:50

Afternoon all,

Is there much noticeable difference between Zodiac's 1100 dtx material, as used on their latest Grand Raid boats and their 1670 dtx material, as used on their workboats? I noticed the 4m Searider also uses the lighter material but the larger Seariders use 1670 dtx.

Having inspected a new Grand Raid last year I must say that the Hypalon didn't seem that heavy/ strong when compared to the RIBs I have operated. We are looking for a new SIB and just wondering if the 1670 dtx boats would be a better long term investment.

Cheers, John

Long term, hard use their is the difference. The maths alone is big.

If you're speccing a new boat, what's the price difference as a percentage of the whole cost?

Probably not a huge difference in the grand scheme of things, might be worth having the heavy stuff for peace of mind.

If it's good quality Hypalon there's a notorious price difference, besides fabric will hold more UV punishment, abrassions, scratches and achieve more tube rigidity. Usually the larger the inflatable, the tougher the fabric.

Thanks folks, I will inspect two boats with the different values and see how they look.

Had a look around an RNLI D Class lifeboat the other day. Anyone know what fabric is used for these boats?

Hypalon ,, except for the very first rfd made ones in the early 1960s that were different more like a rubberised canvas .

I was wondering more about the weight of the fabric? We have been looking at some different boats with a view to buying a new one. After a heavy duty boat, probably with 1670 dtx fabric. The D Class material seemed very good indeed, just wondered what weight it was. Is it made in house or do the RNLI buy it from a supplier?

1670 dtex Hypalon fabric used to be fabricated in 1300 & 1500 gr/square mt. Seems that have standarized it to 1500. From there you jump to 1880 dtex 2210 gr/square mt.

Usually everybody buys fabric from a supplier to make their own tubes or by a tube manufacturer with their tech specifications. Probably RNLI buys finished ribs from a manufacturer with its own specifications.

You could contact the brand rib Company and ask for a quote to build a 1670/1500 gr/sqmt Orca Hypalon rib for you in the lenght of your choice.

Happy Boating

Cheers. I have sent a request to a few manufacturers, it will be interesting to see the cost difference for a boat made with the heavier 1670 fabric. I will post back here when I get some replies.

If it's Orca Hypalon 1670 dtex is 866. Should be quite more expensive compared to Orca 828 which is about the standard use now a days for larger ribs. Post quotes to have an idea about prices.

Happy Boating
