Carbon fibre ribs video

Watch the movie. These boats are pretty cool

There was a writeup in RIB mag on tha boat a while back. They said it was a 9m hull that, with no engine, weighed about a quarter of a ton empty! Seem to remember they said the ride was spooky because of the energy absorbing properties of the carbon fibre hull (same reason the F1 drivers can plant a car into a wall at 100mph and walk away). Certainly looks good in that video.

Awesome boat - and awesome price - I think the test boat was about £100k with a Volvo D3 in it - but "when I win the lottery"

yeah I think that was the article of Paul Lemmer. It's on their web site.

About the hull weight, its true. The properties of autoclaved prepreg carbon fibre are truly amazing. The clear coated carbon fibre also gives a real sophisticated design look.

They have built some Yacht Tenders as well. Last is the 8.3M Xtender

And the net result of all that weight saving? The slightest hint of a wave and the bloody things airborne

A couple of times in the video the bow seemed to disappear underwater

The Atlantic 85's are carbon fibre not sure if it was done for weight saving or just to make them stronger?

One can use and apply carbon fibre the same way as using glas fibre.
Unique here is the construction technology to use prepreg carbon fibre and cure it in an autoclave.
It is a technique used to have the optmized fibre-resin ratio AND taking best advantage of the properties of carbon fibre. The technique is used in aerospace and formula 1 racing.

Carbon fibre does not know fatigue like glass fibre or aluminum.

Using this contruction technology, one can build everything as light and strong as technology allows us today.
The lighter in weight, the better the performance on the water. Lighter weight goes with significant savings on fuel cost, which also decreases carbon footprint.

It is simply interesting!
You can also watch a video of Marström. They are specialized using this technology, and build the hulls and interior assets of the eXtreme ribs.

Marström does not only build ribs, but also catamarans, masts, etc.
It's not that I want to promote them, but the technology they apply in the Marine industry is interesting.

I have heard crew lambast them as being much more flighty than the 75s. Unpredictable was the word used, IIRC.....

I bet it uses less fuel than yours

I didn't know that, no expense spared then! the new pac 24s are carbon as well, £400k's worth

By a fair margin too! I don't dispute that using a lighter, stronger material is a big advantage, if I had a carbon fibre rib I'd have huge fuel tanks which I could fill when I wanted ballast.

It seemed to be heading for a stop at 02:08, a proper stuffing perhaps.
