Why aren't offshore tunnel hulls using forward wings to control bow lift?

And flip they do, too. Pretty amazing.

You forgot to check that you were using hydroplane video from the era BEFORE they installed front wings. Look more closely, <removed>.

 

Sherlock? Well that is a major step up from the last post at least..the one you so quickly deleted. Thanks for that anyway.

 

You were wrong. You know, as in NOT RIGHT, as in MISTAKEN, as in INCORRECT.

GET OVER IT.

 

Wrong about what, exactly? I don't recall asserting anything recently...

You were too ignorant about hydroplanes to know that front wings are a comparatively recent innovation, but attempted to refute my point anyway by using old video as if the now obsolete designs shown represented the current state of the art.

Very first clip. U-7, 2009. And you can clearly see the canard being deflected hard over but far too late to affect the blow-over.

Amazing footage.

 

In case you hadn't noticed, Unlimited hydroplanes are STILL being built with wings installed.

 

There is no such thing as 100% safe.

If an offshore boat launches off a 3' wave or wake and catches air in the tunnel, how large would an aerodynamic control surface have to be? To counteract that in 1 second? And not stuff the bow then.

 

Bottom line is if it reaches a critical angle of attack an Unlimited hydroplane MIGHT blowover where as an offshore big tunnel hull WILL blowover, and there`s hardly a single poster who has demonstrated the slightest capacity to imagine that can be any different.

 

One simple thing you have overlooked Franklin, is that Offshore cat's have adjustable trim via the propshaft angles, hence trimming the angle of attack on the hull, simliar to formula one tunnel boats...... which also do not run a canard wing.............Hydroplanes don't adjustable prop trim

But of course you knew that right??

The offshore cat also weight a heap more than a Unlimited hydroplane, that WILL help stop it blowing over

But you also knew that too...........

 

What I know is. <removed>, even though blowovers use the stern as a pivot once a blowover has initiated there is not a f**king thing you can do at the stern to do a damn thing about it.

 

Unlimited hydroplanes are a lot heavier than Grand Prix/Formula One boats, but they still both blowover. Weight doesn`t do jacksquat to help.
