The big difference is the comfort onboard, you feel practically no declereration in a stuffing incident as the bow simply cuts into the oncoming wave!
...Much like a traditional deep vee hard boat then!

OK, I know you'll expecting this, but what the heck!

You must be expecting this!

But who would actually want a hard boat?

Hard nose only or tube just not attached very well ?

Well I dont think we realy have looked into things fully yet and I am still on the fence.


Ask yourselves this question.Is this bow tube fixing strong enough for the stresses, with a 5 ton offshore Cabin rib attached.

If the conclusion is it looks like a little skimpy and the flange/tube seems to have no real bow/side support or carrier for the tubes,Isnt it a little to soon to put this one to bed in favour of a hard nose only unless your selling the concept ?

Could it just be a weekness in the tube attachment to the hull design for Mikes Cabin rib,that when sorted will be fine in the future ?

Just an observation?

front end look,Should there be some support /cradle

Surly if you stuff this with a 5 ton boat at 30 knts, the tube is likely to come off? IMHO

Should there be some sort of support/cradle for the tube.?

here in canada most of the larger ribs are fastened with a bolting flange. the tubes being ripped off is human error. NOT KNOWING HOW TO OPERATE. sure you can get poor quality here and there. If you are doing more with your boat than it was designed for r you not asking for trouble?

Tube Design

Rather than think of boat design or hard nose design did anyone stop to think about the tube design or capabilities? I would doubt very much if a Hypalon tube whether bolted or glued onto flanges was designed to take the force of a 5 ton 30+knots rib being stuffed into a solid wall of water.
When tubes started getting put onto hulls it was about 30+ years ago and the boat were all under about 21' with small horsepower! Surely now that the ribs are getting bigger, faster and heavier starting to look at ways of protecting the tubes from unnecessary punishment is nothing more than progression in rib design rather than a marketing ploy!
The design of everything changes and evolves as the years go on and as the machinery and equipment they use gets better. Look at motor sport for example!

You are about to fall into Jon Fullers hands here. I can just see his comment “Overcome the tube issue in a big RIB by removing them" "....and now you have a hard boat"

Being no expert on anything what-so-ever is the sea-keeping capabilities of a tubed boat with a hard nose the best compromise or would you suggest other areas of the boat have the tubes reduced in profile or even removed.

Regards

Mark

Hard or Soft.

Fabio Buzzi would seem to know the answer to this question
