tube length

[scubaqua]

Hello all,

I have bought me a new rib, based on a demo boat.
I received some pictures now of my coat and notice that the tubelength which stick out behind my transom, are about (as far i can guess from the photo) about 15cm longer.
Is this a advantage or more a disadvantage?

I can imagine when laying still the boat is more stable, and also when driving the boat?
Also i think the topspeed is less, but is for me not very important.
Is there more, I am wondering?

Thank you for any reply!

See attached pic for what I mean.

Plane's better and quicker. As in more stable at higher speeds in rougher seas. It helps anyways. I dont know if it affects top speed at all someone else can answer that!

Ok, thanks for your reply. Hadn't thought about that.
This off course because the rear of the boat can't be pressed down. (or at least it is more difficult)

Yes exactly the extension of tubes means the boat stays more level when accelerating rapidly. Of course downside is you catch the bloody things when turning off tight from a jetty. Wouldnt damage those tubes but mine has solid steps on the end which have had a few knocks!

That looks like a deep cut out in the transom for the engine, maybe the tubes are extended to increase the buoyancy & improve the freeboard.
